Here comes one of the largest coronal holes of Solar Cycle 25 so far! The time lapse spans the past 5 days of coronal hole(s) CH34+CH37 rotating into Earth-facing position. The CIR (Corotating Interaction Region) ahead of the fast solar wind stream is beginning to affect the Earth. The fast solar wind will be here in 1-2 days. SWPC has issued a G2 geomagnetic storm watch for Tuesday, April 22nd.

On April 21st, at 27.4 degrees from the Sun, Mercury reaches its maximum western elongation. Mercury will be at its maximum point above the horizon in the early sky at this hour, making it the ideal time to see it. Just before sunrise, look for the planet low in the eastern sky.

From April 9–12, Mars will align with the twin stars of Gemini (Castor and Pollux), creating a line that looks like Orion’s Belt. This rare event lets you see two “belts” in the night sky at once, an unusual and beautiful sight.
Gemini’s Twins: Castor and Pollux are the brightest stars in Gemini and usually appear side by side. Mars passing between or near them in a straight line is uncommon.
Orion’s Belt: Made of three bright stars (Alnitak, Alnilam, Mintaka), it's one of the most recognizable features in the sky.
Viewing Tips: Look east shortly after sunset. Mars has a reddish hue, which makes it stand out. Binoculars help, but it’s visible with the naked eye.

A European conference on the status of space debris had experts calling for immediate action to not just prevent but actively clean up the problem.

This is what a Picket Fence Aurora looks like, and is almost always associated with a SAID event.

🌓 5 April: First Quarter Moon at 2:16 UT (now).
The days around First Quarter Moon are the best time to view craters and many other lunar features. Use binoculars or, better still, a telescope for some incredible views. 🔭

One thing went right today! The skies have cleared sufficiently to see tonight's lunar eclipse. Still in its partial phase right now. Got this pic thru the 7-inch telescope at the @RASC Observatory at @TWoSEdm
Step outside & see for yourself!
Eclipse will become total at 0026 MDT

The entire inner Solay System is clustered in the WSW sky just now in the clear Edmonton sky. Venus & 2 day old crescent Moon are obvious, Mercury is much lower but quite bright just now, drop straight down from Venus & a bit to the right.

Planetary Parade: there's still time to see it!
The planetary parade lasts several weeks, not just one night. The information below is based on the view in southern Ontario, so check Stellarium to see what your view will be wherever you are.

Comets can be huge. When far from the Sun, a comet's size usually refers to its hard nucleus of ice and rock, which typically spans a few kilometers -- smaller than even a small moon. When nearing the Sun, however, this nucleus can eject dust and gas and leave a thin tail that can spread to an enormous length -- even greater than the distance between the Earth and the Sun. Pictured, C/2024 G3 (ATLAS) sports a tail of sunlight-reflecting dust and glowing gas that spans several times the apparent size of a full moon, appearing even larger on long duration camera images than to the unaided eye. The featured image shows impressive Comet ATLAS over trees and a grass field in Sierras de Mahoma, San Jose, Uruguay about a week ago. After being prominent in the sunset skies of Earth's southern hemisphere, Comet G3 ATLAS is now fading as it moves away from the Sun, making its impressive tails increasingly hard to see.
