(cba:news) V2491 Cyg (Joe Patterson) [2008-06-05T19:49:14Z]



Dear CBAers,

There's quite an interesting new nova in the morning sky this month (and last): V2491 Cyg, at 19h 43m 2.1s +32d 19m 12.8s. It has become a supersoft source, and my guess is that it's powering a nice orbital signal around now (or perhaps in a few weeks)... from reprocessing in the atmosphere of the orbiting secondary. Let's have a look and see! A few nights of light curve will suffice... and if the answer's no, try again in a month. Nice experiment - the WD-facing hemisphere of the secondary acts as a "bolometer" for the hot WD.

GW Lib and SDSS1627+12 continue to be excellent targets, too!
