Variable Star Organisations


American Association of Variable Star Observers: Easily the biggest, most important and most internationalised variable star orginisation in the world. You don't have to be a member to make use of its extensive facilities, information, and databases - and you really have to if you are serious about variables. More about AAVSO.

AAVSO have several alert lists and email groups.


British Astronomical Association, Variable Star Section: World's oldest (and some would say highest-quality) amateur-based variable star organisation. Their website is worth a thorough investigation.


Center for Backyard Astrophysics 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 - but don't expect any feedback. Join their CBA-Chat and CBA-news e-groups - very valuable.
