Request for observations of FS Aurigae


December 4, 2010: Further to AAVSO Alert Notice 428, the star FS Aurigae appears to be entering outburst.  The star was in quiescence on 2010 December 3.22 (JD 2455533.72; V = 16.3, G. Lubcke) but had risen to V=14.9 on 2010 December 4.23 (JD 2455534.73; R. Campbell).  Subsequent observations by H. McGee and A. Novichonok have confirmed that FS Aur is rising.  Time series observations of FS Aurigae are encouraged at this time; any and all filters may be used including clear, but V filter is preferred. Please continue to follow FS Aurigae throughout outburst until it returns to quiesence.

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

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