The Center for Basement Astrophysics (CBA) was founded by David Skillman in the 1970s as a sort of counter-culture version of the perhaps better-known institute in Cambridge, Massachusetts. The single product of the CBA was, and still is, light curves of variable stars.

Runs monthly campaigns on southern (also northern) cataclysmic variables. See website for current targets, observing and data submission requirements.

It’s kept as simple as can be so that anyone with a CCD can contribute.

Join their CBA-Chat and CBA-news e-groups – very valuable.
