DFAC EVENTS

These are our currently scheduled club events. Older events remain listed just to show the types of things we’ve been up to. For potential DFAC members, browsing this list of events is a great way to find out if DFAC is the right club for you. You’ll always find this list retroactive by at least one year. Observing events tend to follow a schedule dictated by our (normally) July through September cloudy monsoon season. We have good years and bad years for weather cancellations.

We don’t do much during the Summer monsoon season. We’ve had Summer Socials at members’ homes many times, enjoyed astronomy related movies as a group with casual dining after, and attended scientific conferences and special lectures at other venues. Our Summer season is as variable as the monsoon.

For weather-dependent events, NWS forecast updates and event status will be posted daily starting 5 days prior to the event.

Our most recent events are at the top.
