Special Notice #235: Request for archival data: V1647 Ori and McNeil's Nebula

February 15, 2011: Dr. Colin Aspin (U. Hawaii) has requested archival images and other observations of the FU Orionis variable V1647 Ori and the surrounding field over the previous 10 years in support of a study of this star.  Aspin writes that he is hoping to obtain more data with which to create a multi-year light curve of this star to put present-day observations in context of its past behavior.

Special Notice #234: 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.
