Saturday Night Observing: Open 7pm-Midnight

Check our weather and the moon phase

Weather permitting, Saturday Night Observing is from 7pm to midnight where volunteer Staff provide guided tours of the sky. Another thing to consider when going to observe is the Phase of the Moon. Many amateur astronomers like the Clear Sky Chart which has a lot of helpful information.
