March is usually filled with many atmospheric-related events. The Vernal (Spring) Equinox, where there is equal day and night time, occurs in March. The first day of Spring is in March. This year there will be a penumbral lunar eclipse on 25th March, paving the way to a solar eclipse in April.
For me, March always signals the return of the Milky Way Galactic Core after it disappears from view in November; at least from my vantage point. The core can be seen in the wee hours of the morning in dark areas, under clear skies, and with no excessive moonlight.
Here is my season opener of the Milky Way, which is about 15 mins of 30-sec data right before sunrise, captured with a Canon 77D + 50mm lens, tracked on an iOptron Skyguider Pro; @ f/2, ISO 1600. I was so excited to see clear skies, which is an endangered species in these times, I quickly set up my gear, and even snapped a few shots with an iPhone 15 Pro (see below). For me, this is definitely a positive start to the season, hoping that there will be many more nights of clear skies. This will give even better opportunities to look up and experience an amazing Universe!
