[vsnet-alert 7446] V2276 Sgr (rare?) outburst

V2276 Sgr (rare?) outburst

   Rod Stubbings has reported that the dwarf nova V2276 Sgr is undergoing
a outburst.  The last reported outburst dates back to 1998, suggesting
a low freqency of outbursts.  Judging from the outburst amplitude (using
the proposed quiescent candidate), the object may be a short-period system
such as an SU UMa-type star.  Close time-series CCD observations are very
strongly encouraged.  Please also send selected CCD images (FITS format)
to Yamaoka-san (yamaoka@rc.kyushu-u.ac.jp) to make accurate outburst
astrometry and quiescent identification.  Good luck!
