Outburst of FS Aurigae

February 14, 2011: Further to AAVSO Alert Notice 428 (2010 Nov 30), the dwarf nova FS Aurigae appears to be in outburst.  The current outburst was detected simultaneously by P. Lake (Wonga Park, Victoria, Australia) at m(vis)=14.5 on 2011 Feb 14.0969 (JD 2455606.5969), and confirmed shortly after by G. Lubcke (Middleton, WI, USA) at around V=14.4 in time-series observations made simultaneously to the observation of Lake.  Follow-up photometry of this star is encouraged. Any and all filters may be used for time-series including clear, but V filter is preferred.  Please continue to follow FS Aur throughout its outburst until it returns to quiesence.  We have been notified by the campaign PI, Vitaly Neustroev (U. of Oulu, Finland), that the campaign goals have been successfully met; following this outburst, nightly monitoring of the star through the end of the observing season is encouraged.  No further Special Notices will be issued for this object.

FS Aur is located at the following (J2000) coordinates:

    RA: 05 47 48.32 , Dec: +28 35 11.6
