[vsnet-alert 2204] Rapid fading of V592 Her

Rapid fading of V592 Her

   A preliminary analysis of Sep. 20 images of V592 Her, taken at Ouda team
rooftop station (K. Matsumoto) has shown the star entered a rapidly fading
stage.  Dwarf novae of the similar type may show early recovery to "second
superoutbursts" (AL Com and USNO 1425.09823278), or repetitive rebrightenings
(EG Cnc).

   Observers with CCDs and suitable telescopes are strongly urged to continue
monitoring the object's behavior after this stage.
