[Aavso-photometry] Shortest period Variables..

[Canopus56]

The VSX database method described upthread is the current 2008 state of the art procedure.  Here's a list of 423 short-period variables that I developed in 2005 from a former AAVSO and Varobs list:

Of 423 short-period variables, 112 have periods of less than 1 day. 

Of interest for your purposes is the tab delimited file that can be imported into astronomical planning software like Rodman's Astroplanner:

Once in Astroplanner, it becomes easy to determine which of the short period variables is currently transiting, are suitable for observation and can be found using a Astoplanner directed GOTO. 

At the time, I was using Patrick Chevalley's VAROBS freeware to predict the best times to observe the lightcurve.
