The Sky for March 2024

The Sky for March 2024

March hosts the “first day of spring”, although someone forgot to tell that to the weather. Astronomically, spring begins when the Earth reaches a specific point in its orbit around the Sun – it’s an easily-measurable instant in time when the Sun rises due east, sets due west, and is in the sky for 12 hours a day. Usually, the weather takes several weeks to catch up to that, but so far Manitoba has had three “winters”, two “autumns” and a “spring” since January 1, so the equinox is becoming less useful as an indicator.

March is also when we “spring ahead”, moving our clocks forward one hour to the poorly-named “Daylight Savings Time”. (Spoiler: no daylight is saved, we just alter our schedule so that people who work 9-5 see a bit more of it after their work day is done.) The official change happens in the morning of March 10th: 1:59 a.m. Central Standard Time is followed by 3:00 a.m. Central Daylight Time. We lose an hour of sleep that night, so expect inattentive drivers, cranky coworkers, and other symptoms of poor sleep to crop up in your life for the following week or so.

 

The Solar System

The planets are described in the order they are most visible in this month’s Manitoba skies. 

Solar System Highlights 

There is a penumbral lunar eclipse on March 24-25 which is visible across Canada. See the Calendar entry below.

Mercury is at its best evening visibility of the year for Canadians, peeking up above the western horizon in evening twilight about the 12th and rising higher each night until greatest elongation from the Sun with occurs on the 19th. It will probably easiest to see on the few days around March 16 when it is as its brightest and near its highest above the horizon. 

Jupiter is visible in the west-southwest after sunset, and sets before midnight local time. Telescopic observers will want to catch it early before it sinks into the turbulent air near the horizon.

Uranus sits above Jupiter in the evening sky, in the direction of the Pleaides star cluster. Only easily spotted in binoculars or a telescope, Uranus looks just like a faint dot of light indistinguishable from any other star.

Mars is higher than Venus in the pre-dawn sky but much fainter, making it difficult to observe until near the end of the month. Mars will return to prominence in the second half of 2024 but until then it remains a less-than-impressive object.

Venus remains very low in the south-southeast just before sunrise,  only visible because of its great brilliance. It passes very close to Saturn on the mornings of March 21 and 22, but the low altitude above the horizon makes this event probably unobservable for Manitobans.

Saturn is invisible for most of the month after its February 28 conjunction with the Sun. It reappears in the morning sky towards the end of the month, very low in the southeast before sunrise.

Neptune reaches solar conjunction on the 17th, and is unobservable for the month.

Celestial Calendar for March 2024

Sun Mar. 3 (evening): A celestial event on Earth – Bill Nye “the Science Guy” will be speaking live at the Manitoba Centennial Concert Hall on his “The End is Nye” tour. Planetarium Astronomer Scott Young will introduce Bill and moderate the Q&A session. Showtime is 7:30 pm.

Fri Mar. 8 (morning): The razor-thin waning crescent Moon is very low below Venus and Mars just before sunset, but all three are very low in the sky and likely invisible unless you have a very clear atmosphere and flat horizon to the southeast.

Fri Mar. 8 (evening): The monthly meeting of the RASC Winnipeg Centre, the Manitoba chapter of Canada’s largest astronomy club. Meetings are open to the public, and details can be found here.

Sat Mar. 9 to Sun Mar 10: Daylight Savings Time begins: Remember to set your non-internet clocks forward 1 hour late on Saturday March 9 or after midnight on Sunday, March 10, to ensure your circadian rhythms are as messed up as everyone else’s. 

Wed Mar. 13 (evening): The waxing crescent Moon is to the right of Jupiter in the evening.

Wed Mar. 14 (evening): The waxing crescent Moon is close to the Pleiades star cluster, with those farther west seeing a closer approach. 

Sat Mar.23: Spring Break begins at the Manitoba Museum! 10 days of programming, exhibits, and hands-on science, plus the premiere of a new planetarium show!

Sun Mar. 24 to Mon Mar. 25 (morning): A minor lunar eclipse occurs in the wee hours of the 25th. Not the “blood moon” of a total lunar eclipse, the moon only passes through the outer part of Earth’s shadow. These penumbral lunar eclipses are easy to miss if you aren’t watching for them, since the bright Moon doesn’t look too different minute to minute and there are no major colour changes. Still, they are interesting to watch, and the Planetarium’s Dome@Home astronomy show will host a live-stream of the event beginning at 11:30 pm on the 24th.

Thu Mar. 28 (evening): Dome@Home, the Manitoba Museum’s award-winning online astronomy show, runs at 7 pm. Central time on the last Thursday of every month on the Museum’s Facebook page and YouTube channel. This episode will feature the April 8 solar eclipse, including how you can safely watch the event as it unfolds from anywhere in Manitoba.

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.
