[vsnet-alert 9165] FO And superoutburst

[Arai Akira]

We confirmed the outburst of FO And as reported by Jose Ripero in vsnet-obs 56750.
FO And is now probably in superoutburst.

We are observing this object in tonight,and the magnitude of this object is now very bright at 13.4C.
We have observed this object over 130 days from the previous superoutburst with a 25-cm and 1.5m telescopes at Higashi-Hiroshima Observatory.
If this outburst is a superoutburst, this is the 2nd superoutburst in this year.
The last superoutburst was in Augest.

Based on our observation, this system has very high frequency of normal outbursts whose cycle is about a week.Such a short cycle is the one of the shortest cycle, like YZ Cnc, in normal SU UMa dwarf novae(except for ER UMa stars).

We prepared a light curve summary page for this object:

Time series observations are encoraged in order to study superhumps in detail.
