Welcome!
The Ryukyu Astronomy Club (RAC) was founded 23 February 2002.
Located in
Okinawa, Japan, RAC members enjoy subtropical weather (no cold weather gear here!) and a view of more southerly objects from a vantage point of 26 degrees North latitude.
Here on our web site you will find copies of our newsletter, articles written by members, resources for download, and more.
Click
here to join our online discussions at Yahoo Groups. All meeting and
special announcements are sent via this discussion group. Check out the
RAC Online Store for hats, shirts and more.
Please provide comments to our
Organizing Committee and thank you for visiting!
