Black Hills Astronomical Society

Rapid City, South Dakota, USA


The Black Hills Astronomical Society (BHAS) meets on the third Monday of every month (September through May), 7:00 p.m., at the Journey Museum, 222 New York Street.  Our meetings begin with a program to which the public is invited free of charge.  Following the program, we have a business meeting which is open to all who are interested.
Our "Star Parties" are held on scheduled Friday evenings in the summer at the Hidden Valley Observatory starting at dusk unless the sky is cloudy or the moon is too near to full.  There is no charge, but donations are welcome.
