Special Notice #377: Reported outburst of the WZ Sge star AL Comae

The membership database is currently undergoing upgrading/testing. Web functions that involve an interface with the member database (webobs, etc.) may experience intermittent problems. We hope to have this issue resolved within 24 hours (by 5pm Eastern Time on October 1st or 12:00 UT). Thank you for your patience.

December 6, 2013: Observer Carlo Gualdoni reports via the cvnet-outburst mailing list that the WZ Sge-type dwarf nova AL Comae is in outburst, with a magnitude of V=12.74 on 2013 December 6.185 (JD 2456633.1185).  Gary Poyner notes on the BAAVSS mailing list that this is the first observed outburst of AL Com since October 2007.  Both visual observations and CCD time series are encouraged.

AL Comae has typically faded quickly during past outbursts, but will exhibit rebrightenings during the event.  Unfiltered time-series observations may be useful to detect any periodic behavior; photometry of the overall outburst is also useful.  The star is fainter than V=20 at quiescence.

AL Com is located at the following (J2000) coordinates:

RA: 12 32 25.9 , Decl: +14 20 43.5

Please report all observations to the AAVSO with the name "AL COM".
