Current Observing Conditions
As you may have noticed, the sky is getting brighter. This is not good for our research and it is not good for your nighttime environment. We will soon be posting more info on how you can help. In the meantime, please turn off unecessary lighting at night. Thanks!

What's Up?

Pardon the construction! We're undergoing renovations. No tours scheduled for winter 2025/2026.
