[vsnet-alert 1303] Possible superoutburst of FO And

[Taichi Kato <tkato>]

Possible superoutburst of FO And

  The light curve is rather complex, suggesting the presence of a precursor.
The brightness and duration suggest a superoutburst.  The latest superoutburst
of FO And occurred in 1997 July, reaching mv=13.6 (Poyner).  The present
supercycle length (~100 d) is one of the shortest among usual SU UMa-type
dwarf novae.
