Skywatch, our public observing program, is scheduled for 2-3 weekends each month. Each event is:

  • On a Friday or Saturday evening;
  • Starts 60-90 minutes after sunset (so the start time changes throughout the year);
  • And is scheduled to last for one hour.

And if it's on the calendar, you can expect it to happen, unless:

  • Weather (usually anything involving clouds, and sometimes low temperatures);
  • Staffing issues (rare, but it could be a thing).

So always check the calendar before you leave your house!

If you don't see the calendar below, rotate your device to landscape.

Because it's too much to include with the one above. The best graphical view is at the week level.
