Announcements:

Our September meeting will be a Zoom meeting at 7pm on Monday the 7th (Labor Day). Dr. Kaitchuck will give a presentation entitled "Next Month's Mars opposition".

Using Zoom is a learning process for all of us, and I'm making some minor changes for our next meeting that should make things go a little more smoothly. The main change that you'll likely notice is that you will no longer need to wait in the lobby and be let in. Instead, clicking the meeting link will take you directly into the meeting.

Here's the info for joining the meeting:
