March 3 there will be (or was) a total lunar eclipse for the western edge of the United States and the western half of Canada. This will be a partial eclipse for the majority of the United States and the eastern half of Canada.
March 20 vernal equinox occurs. Yay, spring is straight ahead!
April 3 Mercury will be at its greatest western elongation.
April 22-23. The Lyrid meteor shower peaks the morning of the 23rd with a ZHR of 10-20. Comet C/1861 G1 Thatcher left behind the particles that make up this shower. The moon will set shortly after midnight, so this should be a better-than-sometimes show.
In early April, Comet C/2025 R3 (PanSTARRS) may be worth keeping an eye on. Currently, it is predicted to be magnitude 5. Look for it low in the eastern sky just before sunrise.
