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.

Database Errors Reported

Some observers in the chat room are reporting that their observations submitted since November 11, 2010 are not showing up in our online tools. Doc and Matt will investigate this first thing in the morning (eastern) and update this page when they know more information. We apologize for this inconvenience.

Update 2011Feb10 0620 ET (by Doc)

Well, its been a far longer day and  night than I thought it would be, and I'm sorry for that.

That being said the AID Database and webobs is back up and running.

Special Notice #233: Bright outburst of the cataclysmic variable SDSS J133941.11+484727.5

February 7, 2011: The star SDSS J133941.11+484727.5 has been reported in outburst by Jeremy Shears (Bunbury, UK).  Shears reports this star at magnitude 10.4 on 2011 February 7.919 (JD 2455600.419).  This is approximately 7 magnitudes above quiescence, which suggests a superoutburst of an SU UMa star or a WZ Sge-like outburst.  Gary Poyner (Birmingham, UK) confirms this outburst, estimating the star at 10.5 on February 7.959 (2455600.459).

New Sequence for SN2011B

There is now a sequence available for SN2011B. 

You will need to specify the coordinates (I used 08 55 48.50 +78 13 02.7 from the discovery telegram) to plot a chart, or you can simply download this E scale DSS image chart and print it.


Special Notice #231: T Pyx Observations Requested

February 1, 2011: Sumner Starrfield (Arizona State University) has informed us that Chandra is currently observing the cataclysmic variable T Pyx.  He and his colleagues would like supporting optical monitoring of the star during the visitation.  One visit is happening now; the next and final visit will occur on February 5 (UT).
