This is the week for the Messier Marathon. As described at the link above, "Messier marathon is an attempt undertaken by amateur astronomers to find as many Messier objects as possible during one night. The Messier catalogue consists of 110 relatively bright deep space objects (galaxies, nebulae, and star clusters)". All 110 objects can only be seen on nights near the new moon closest to the equinox.
We plan to go to our local observatory, Bruneau Dunes State Park, to see at least the first few hours worth of objects.
Here is the Bruneau Sky Clock if you are interested:
The clock shows the forecasted viewing conditions. Darker colors are better. Click on the clock to get instructions for reading it.
