Final Week of Astro-April: SEVEN more online talks!

The AASVO's Citizen Sky Project has been producing a series of online talks as a part of a month-long celebration called Astro-April.

In the last couple of weeks we have presented 5 online talks on various astronomical subjects.  (If you missed any of them, recordings are posted on the main Astro-April page.)  The speakers have been engaging, the questions have been thoughtful, and we've given away $250 in "door" prizes!
