The Sky for August 2024

The Sky for August 2024

August brings the return of some planets to the evening sky, the most famous meteor shower of the year, and longer nights than we’ve seen for a couple of months. The Milky Way is on full display, offering an unforgettable view from a dark, moonless sky. Unfortunately all of these benefits will likely be offset by smoke in the air from forest fires across Canada, which has become a fixture of summertime observing for the last several years.

The Perseid Meteor Shower

The annual Perseid meteor shower is the most famous meteor shower of the year, although it is not the best one of the year. Its occurrence in August during summer vacation likely makes it more accessible than the much better Geminids, which occur in mid-December. For a complete rundown on the Perseid meteor shower, check out this blog post.

2024 is a good year for the Perseids, since the peak time occurs with the Moon out of the sky. The thing about meteor showers is, they peak in the few hours before dawn for any given location. So to see the Perseids at their best, you want to observe from about 1:30 a.m. to dawn. There will be almost no meteors before midnight – you might see one or two, and the ones you do see will likely be bright ones, but it won’t be much of a “shower” unless you stay up all night.

To observe the Perseids, get away from city lights. Light pollution will wash out the fainter meteors, and there are a lot more faint meteors than bright ones. Bring a reclining lawn chair and blanket to ward off the early-morning chill, and set up facing the darkest part of the sky (or straight up, if you’re in a nice dark spot). Turn off your electronic devices and your car’s lights – any stray light will make it hard to see the meteors for you and anyone near you. The meteors only last a second or two, so you need to watch the sky continuously – literally, don’t blink or you’ll miss it.

You can also try and take pictures of meteors – set up your camera on a tripod and take a bunch of time exposures of the sky. If you’re lucky, a meteor will happen while you’re taking a picture.

We’d love to show your Perseid pics on Dome@Home, our online astronomy show. Send them to space@manitobamuseum.ca and then tune in to our August 28th show at 7 p.m. Central on the Museum’s Facebook and YouTube channels.

The Solar System

Finally, some planets are visible in the evening sky! Barely…

Mercury is still on the evening side of the sky, but in August it sets just after the Sun and so isn’t visible for Canadian viewers. Folks farther south still have have a chance to catch it early in the month, low in the west just after sunset.

Venus has appeared in the evening sky, although like Mercury it is still low in the sky; only its great brightness allows it to be spotted very low soon after sunset. The thin crescent moon is nearby on August 5th.

Mars rises about 2 a.m. local time in the northeast, inconspicuous compared to nearby Jupiter and both the Pleaides and Hyades star clusters. Mars and Jupiter pass less than half a degree apart on the morning of August 14th; see the Sky Calendar entry below for details.

A simulated view of Saturn and its rings.

Jupiter is the brightest “star” in the eastern sky after midnight, outshining all the visible stars as it cruises through the stars of Taurus. The waning crescent Moon is nearby on the morning of August 27.

Saturn rises about 11 p.m. local time early in the month, and moves into the south by dawn. The ringed planet reaches opposition on September 8, so it’s coming into its best viewing position for the year. The rings are only tilted about 4 degrees to our line of sight, making them appear very thin from our point of view. The nearly-full Moon is to Saturn’s left on the evening of the 21st.

Aug 4: New Moon

Aug 11 – Aug 12 (morning sky): Best viewing for the annual Perseids meteor shower; see featured article above. Decent rates should occur the morning before and after as well.

Aug 12 (evening sky): First Quarter Moon

Aug 14 (morning sky): Jupiter and Mars are close together in the morning sky, separated by less than the size of the Full Moon. They’re still pretty close the morning before and after this date.

Aug 19: Full Moon

Aug 20-21 (after midnight into morning sky): The waxing gibbous Moon is to the left of and slightly above Saturn. The two are only about 3 degrees (6 Full Moon diameters) apart, fitting easily into the same binocular field-of-view.

Aug 26: Last Quarter Moon

Aug 27 (morning sky): The waning crescent Moon is above Jupiter, rising together in the morning sky about 1 a.m. local time in the morning sky. Mars is below and to the left, forming a not-quite-right triangle. The red supergiant star Aldebaran is to Jupiter’s right along with the Hyades star cluster, with the Pleaides above them all. The morning rising of these star clusters remind us that winter is coming.

Aug 28 (morning sky): The Moon, Mars, and Jupiter form a very squashed triangle pointing downwards in the eastern sky before dawn.

Aug: 29 (morning sky): By this morning the Moon has moved farther on, still forming a rough line with Mars and Jupiter in the early morning sky.

Meteor Showers in Summer (2024 Edition)

Meteors

A meteor (a.k.a. falling star, shooting star) looks like a bright streak across the starry sky that lasts for a second or two before fading away. Most people believe they are rare enough that you should make a wish when you see one, but they are surprisingly common if you watch the sky a lot. On any given night with no Moon, if you get away from city lights and watch the sky continuously, you’ll see up to a half-dozen meteors per hour. Any light sources – the Moon, city lights, you phone – will reduce that number to near zero.

Each meteor you see is actually a tiny piece of dust about the size of a grain of sand which is burning up in the Earth’s atmosphere. Space isn’t empty, you see – it’s dusty, with all the dust leftover from the big construction job that was the formation of the solar system. As the Earth orbit the Sun, it plows through the dust at over 100,000 kilometers per hour. It’s a one-sided collision, and the poor speck of dust disintegrates in a flash of light that we can see from the ground as a meteor.

Meteor Showers

So far, so good – you can see these little specks of dust as they vaporize, and they pretty much occur randomly all the time, we just don’t usually notice. But, it turns out that space isn’t evenly dusty. There are spots, just like in your house, that have more dust than others. In my house, these dust bunnies congregate under the furniture and anyplace the air vents push them; in the solar system these dust bunnies remain where they were shed, in the orbital paths of comets. The solar system is crisscrossed by trails of dust left behind by various comets (and a few asteroids). If the Earth’s orbit intersects one of those trails, we will fly through an interplanetary dust bunny every year around the same time. That’s a meteor shower.

The name “meteor shower” makes you think you can see a lot more meteors than on other nights. But here’s the thing: “a lot” can mean different things. Forty times the normal rate sounds like a lot, until you remember it’s forty times about one meteor per hour. There are over a hundred meteor showers catalogued, but there are only a couple of meteor showers a year that produce more than forty meteors an hour. Even during an official meteor “shower”, you can probably only expect to see a half-dozen meteors per hour, and that’s under perfect skies with your eyes watching the sky 100% of the time.

The Perseids for 2024

So, most meteor showers don’t produce many meteors; that’s the bad news. The good news is, the Perseids in August is one of them, which makes them probably the most famous meteor shower of all. And, in 2024 the Moon will be out of the sky during the crucial morning hours. If you can get away from city lights under a clear, dark sky, you might see up to 60 meteors an hour – one a minute – in the early morning hours of August 12.

That’s pretty specific timing, but luckily the Perseids “dust bunny” is more than one day wide. The Earth actually enters the outer edge of it in late July, and each morning the rates will increase until the peak on the 11th-12th. So, we have several chances to see a decent Perseids display this year.

The key point to remember is that all meteor showers are best between about 1:30 a.m. and 5 a.m. local time. Pre-midnight observing might be 1/10 or less of the morning rates. Really, you have to stay up all night to see this.

To get the best view, get as far away from city lights as practical, and set up a reclining lawn chair or blanket so you can lean back and see as much of the sky as possible. Keep all the lights around you off, especially if you are in a park of other spot with other observers. One peek at your phone will shut off the natural night vision of your eyes for up to ten minutes, so you really need to avoid looking at any lights. (If you need to keep your car running, cover the headlights with a blanket or something so you don’t blast the whole park with your lights!) If you have any lights nearby, put them behind you out of your view, and just watch the sky. You don’t need a telescope or binoculars – in fact, those instruments restrict your field of view so much that you probably won’t see any meteors through them at all. The meteors can appear anywhere in the sky, and they only last a second or two – literally, don’t blink or you can miss them.

Meteors and Cameras

You can take pictures of meteors, but it involves a little luck, and some understanding of your camera. If you have a DSLR or mirrorless camera, you can put it on a tripod and set your exposure manually for something like 5 or 10 seconds – you’ll get a lot of pictures of stars, but if you’re lucky a meteor will happen while you’re shooting, and it will show up in one picture.

If you’re using your phone camera, you might need to download a better camera app than the one your phone came with – check out the app store for one that is designed for night or sky photography. The same tactic applies – take lots of pictures, and hope you catch one. Make sure the light from your camera doesn’t interfere with your vision, though – just take the pictures now, and look at them later.

One thing to watch for: satellites. There are piles of satellites that will show up in your images as streaks of light. You can tell satellites by the trail being the same brightness and thickness throughout; meteors tend to start faint and narrow, get brighter and wider, and then trail out again.

Other Summer Meteor Showers

While technically there are other meteor showers in July and August, in practice these are not noticeable to the average observer and are scientific designations only. They’re named after the constellation or star that the meteors appear to radiate from, but most of them produce a meteor every couple of hours or so – not even a spritzing, let alone a shower. Even the bigger South Delta Aquariid meteor shower, which peaks in late July, only produces about 5 meteors an hour at best. If you are interested in these minor meteor showers, there is backyard science that can be done by tracking them with a camera, though; visit the International Meteor Organization for some great information on getting deeper into the science of meteor observing.

tl;dr: The morning of August 12th between 1:30 a.m. and 4:30 a.m. you will probably see quite a few meteors. The morning before and after, you’ll still see a good number. The rest of the summer, you’ll hardly see any, but you might see one anytime you are looking at the stars.

The Sky for July 2024

The Visible Planets

For planets, early morning is the time to observe. Although Saturn rises shortly after midnight, it stays low until the early morning hours. For unaided eye viewing you can catch it anytime after midnight, but telescope viewers should wait until it rises out of the thick murky (and probably smoky) air near the horizon for the clearest views.

Mercury moves into the evening sky this month, but the geometry keeps it very low to the horizon. It will be very difficult to catch even with binoculars, probably lost in the bright twilight after sunset. The best time to try for it is on the evening of July 7, when the thin crescent Moon will act as a pointer (see Sky Calendar below).

Venus reaches perihelion, the closest point to the Sun in its orbit, on July 10, but the same geometry keeps it very low in the west after sunset. What is the first day you can spot it with the unaided eye?

Earth reaches aphelion, the farthest point to the Sun in its orbit, on July 5. The slight change in the Earth-Sun distance doesn’t cause the seasons, but it does influence how long they are – this is why northern hemisphere summer weather (which occurs in July and August) is less pronounced than southern hemisphere summer weather (which occurs in January, when the Earth is closest to the Sun).

Mars spends the month in the morning sky, edging closer to the famous Pleiades star cluster and the planet Jupiter. It rises about 2:30 a.m. local time at the beginning of July and by 1:30 a.m. local time by month’s end. Still distant, it appears too small in a telescope for very good views.

Jupiter rises about 3:30 a.m. in the east-southeast, the brightest object in this part of the sky and just above the V-shaped star cluster that marks the face of Taurus the Bull. By month’s end it rises before 2 a.m. and forms a pretty triangle with Mars and the bright star Aldebaran.

Saturn is getting high enough this month for decent telescopic views, but you’ll have to get up early. The ringed planet rises shortly after midnight in early July and by 10:30 p.m. at the end of the month, but it will be at its best telescopic view when at its highest, in the early morning sky a couple of hours before dawn. Saturn’s 29.5-year orbit around the Sun gives us a differing angle to views the amazing rings of Saturn, and this year we see them almost edge-on. While this makes it less impressive than other years, they are still an amazing sight in any telescope. This geometry also opens up a series of events for Saturn’s 146 moons, several of which will transit across the planet’s disk or cast their shadow onto the cloud-tops.

The Outer Planets

All of these objects require binoculars or a telescope to spot. Due to their distance, they appear as tiny spots or star-like points, and will require a good star atlas or app to positively identify them. Try Stellarium’s web version or the free Stellarium program for PC.

Uranus is near Mars in the morning sky, but you’ll need binoculars to see it as a tiny faint “star” among a sea of other stars. Your best chance will be in mid-July, when the two planets pass within a degree of each other – that’s about twice the apparent size of the Moon int he sky. See the Sky Calendar entry for July 15th for details.
Neptune is near Saturn in our sky, but you’ll need large binoculars or a telescope plus a good star chart or app to track it down.
Dwarf planet Pluto reaches opposition on July 23, whicvh usually means a planet is at its brightest and most visible. That’s true in this case, however for Pluto, “best” is relative. It’s so small and distant that you’ll need a good-sized telescope to be able to identify it.

Comets

In July there is one comet within the range of binoculars. Comet 13P/Olbers was last visible from Earth in 1956, and takes 69 years to orbit the Sun. On this pass through the inner solar system (called the comet’s “apparition”), Comet Olbers passed closest to the Sun on June 30th and is now slowly swinging back into the depths of space. It is visible in July in the evening sky low in the northwest after darkness falls, travelling slowly through the little-known constellations of Lynx and Leo Minor (down below the feet of Ursa major the Great Bear).

Comet Olbers is probably visible in binoculars only from a dark sky as a faint fuzzy spot without a tail. Recent images of the comet show a detailed blue ion tail and a wide diffuse dust tail, but these will only be visible in long-exposure telescope images. Still, spotting one of these celestial interlopers on their uncommon passes through the solar system reminds us of how many small bodies in the solar system are out there, just below the limit of our visibility.

Sky Calendar for July 2024

3 Jul 2024 (morning sky): The crescent Moon sits to the upper left of Jupiter in the east-north-east, both fitting comfortably into a binocular field of view. The two form the base of a triangle with the Pleaides at its apex. Mars is farther east and higher.

5 Jul 2024: New Moon occurs at 5:57 p.m. CDT.

7 Jul 2024 (evening sky): The crescent Moon and Mercury are in the same binocular field. Mercury is to the lower right of the Moon, but sets soon after the Sun so you’ll need a very clear horizon and good timing to spot them.

13 Jul 2024: First Quarter Moon occurs at 5:49 p.m. CDT.

15 Jul 2024 (morning sky): Bright Mars passes close to distant Uranus, so close that they’ll be visible in the same field of view of most telescopes for several days centered on the 15th.

17 Jul 2024 (evening sky): The waxing gibbous Moon is to the left of the bright red star Antares, very low in the south. The Moon actually passed in front of (or occulted) the star about 2pm this afternoon, but it wasn’t visible on this side of the Earth.

21 Jul 2024: Full Moon occurs at 5:17 a.m. CDT.

23 Jul 2024: The dwarf planet Pluto reaches opposition, the point when it is opposite the Sun and visible all night. Unfortunately, its position in the southern sky makes Pluto a difficult observation from Canada this year without electronic imaging or travel.

24 Jul 2024 (morning sky): The waning gibbous Moon is to the right of Saturn this evening, but far enough away that they won’t both fit into the field of view of typical binoculars. The Moon will occult (pass in front of) Saturn later today, but it is not visible from Manitoba.

27 Jul 2024: Last Quarter Moon occurs at 9:51 p.m. CDT.

28 Jul 2024 (morning sky): Technically the peak of the Pisces Australis meteor shower, but it is not really a northern hemisphere event.

30 July 2024 (morning sky): The South Delta Aquariids peaks in the pre-dawn hours this morning. See “Meteor Showers” below.

Other Events

Meteor Showers

This month there are two meteor showers (although neither is a “big” one). The one perhaps worth watching is the South Delta Aquariid meteor shower, which is slowly building throughout July to a peak on the morning of July 30. Patient observers may spot a dozen or more meteors per hour from this shower in the pre-dawn hours of the 30th. (Compare this to the typical 2 or 3 so meteors per hour you can see on any summer night.)

Technically, the Piscid Australis meteor shower also peaks in July, and you’ll see it listed in several sky calendars, but it will contribute less than 1 meteor per hour to Manitoba skies at best, so it is mentioned here only so you don’t get too hyped up over a listing elsewhere.

“The Blaze Star”

A note that T Corona Borealis, the so-called “Blaze Star”, is expected to go nova sometime this summer, brightening to about 2nd magnitude (about the brightness of the stars in the Big Dipper). It is located just beside the “crown” or Corona Borealis, and is normally too faint to find without a telescope. It is a double star system that has a massive eruption in brightness every 80 years or so, and observations indicate it could go at any moment. Watch for an upcoming blog detailing how you can see this rare event, and how simple observations anyone can do can contribute to our scientific understanding of this amazing star system.

Manitoba Skies for December 2023

December provides long winter nights for observing and features the best meteor shower of the year as well as the return of the winter constellations to early evening prominence. Colder temperatures can make observing more difficult, since astronomy is not an aerobic activity! Dress in layers, and plan for a temperature at least 10 degrees colder than the forecast. Good boots and a warm hat are the most important accessories. 

Visible Solar System 

Saturn is nearly gone, low in the southwest after darkness falls. This hasn’t been a great year for observing the ringed planet since it has been so low in the sky from Manitoba.  

Jupiter is already fairly high in the east-southeast as darkness falls, and rises into the south by mid-evening, providing clear views for Canadian observers. Binoculars show several of its four largest moons, and a telescope will reveal cloud bands and structure in the gas giant planet’s atmosphere. 

Venus rises about 4 a.m. local time at the beginning of December. It stands about 20 degrees up in the southeast before dawn but rises later and loses altitude throughout the month.   

Mercury begins to creep above the eastern horizon at dawn towards the end of the month but is more easily visible in the first week of January. Even so, Manitobans will have a tough time spotting it in the bright twilight just before sunrise. We’ll have a better chance in March when Mercury is visible in the evening sky. 

Mars is on the far side of the Sun this month, too close to the Sun to be visible in the morning sky. 

Calendar of Celestial Events

(All event dates and times are local times for Manitoba – Central Standard Time. Almost all events are visible across Canada, though – just use your local time instead. The exception is an event like the Solstice or a specific phase of the Moon, which happens at a specific time and date. In those cases, you have to adjust to your local time by adding or subtracting time zones.)

Mon 4 Dec 2023: Last Quarter Moon occurs just before midnight Manitoba time tonight, so many calendars that use Eastern Time or Universal/Greenwich Time will show it on Dec 5th instead. 

Sat 9 Dec 2023 (morning): The waning crescent Moon is 4° to Venus’ lower right. 

Tue 12 Dec 2023: New Moon 

Wed 13 Dec 2023 (evening) through Thu 14 Dec 2023 (Thu): The annual Geminid meteor shower peaks overnight, with the nearly new Moon providing dark skies. With a theoretical rate of over a hundred meteors per hour for most of Canada, this is the meteor shower to see. You’ll want to get to dark rural skies and be well-prepared for a long night of winter observing. Pay particular attention to your vehicle if the temperatures are low, as being stuck in the middle of nowhere on a cold December night can be dangerous. 

The Geminids are also one of the few meteor showers that are active before midnight, making them a bit more accessible than other showers such as the Perseids in August, which are at their best in the few hours before dawn. For details on how to turn your meteor watching into scientifically useful data, visit the International Meteor Organization’s Geminid page.

Sun 17 Dec 2023 (evening): The waxing crescent Moon is about 3° below Saturn. 

Tue 19 Dec 2023: First Quarter Moon 

Thu 21 Dec 2023 (evening): The waxing gibbous Moon is far to Jupiter’s right.  

Thu 21 Dec 2023: Also tonight, the winter solstice occurs at 9:27 p.m. CST, marking the sun’s farthest movement south in our skies. This translates into the late sunsets and long winter nights of winter. After this date, the sun will rise earlier each day, and the number of daylight hours will begin to increase. 

Fri 22 Dec 2023 (evening): The waxing gibbous Moon is far to Jupiter’s left. 

Tue 26 Dec 2023: Full Moon 

Thu 28 Dec 2023 (evening): The Manitoba Museum’s award-winning online astronomy show Dome@Home airs at 7 p.m. CST, live on the Museum’s Facebook and YouTube pages. Dome@Home covers the celestial sights and events visible in the coming month, and highlights some of the cool space stuff that’s happened in recent weeks.  

Sun 31 Dec 2023: The last day of the Gregorian calendar which is used in most parts of the world including Canada.
