  This object may be an SU UMa-type dwarf nova.  During the 2007 July
long outburst, ASAS-3 recorded a fading rate compatible with
an SU UMa-type superoutburst.  Although the present outburst is much
fainter, it might evolve into a superoutburst assuming a supercycle
of a year or so.  Time-resolved photometry would be encouraged.

  Past information:

  [vsnet-campaign 388]

  Relatively rare outburst.  The last outburst occurred in 2000 March.
The 1999 December outburst looks like a superoutburst; time-resolved
photometry during long, bright outburst is encouraged.  Possible VSNET
campaign target star.

  Further brightening has been observed, reaching the brightest level in 
the past.  The object is at mag 18 in quiescence, so the present outburst
has a chance of a superoutburst (or a large-amplitude SS Cyg star).
Time-resolved photometry is strongly needed to clarify its nature.
