AAVSO Alert Notice 371

Support for XMM-Newton Observations of SS Aurigae
March 6, 2008

Dr. Patrick Godon (Villanova University / STScI) requests observations
of the dwarf nova SS Aurigae (AAVSO Designation 0605+47) during the next
several weeks in support of XMM-Newton X-ray observations.  They request
nightly visual and instrumental observations to determine whether the
star was in outburst or quiescence during the observation scheduled for
2008 March 22/23 UT.  Observations before, during, and after the
scheduled X-ray observations will be used in their final analysis. 
Please begin observing now, and continue until at least April 5.

SS Aurigae is a well-observed dwarf nova, though it is faint in
quiescence at around m(vis) = 16.  Visual positive and fainter-than
observations, and all instrumental photometry will be useful to
determine whether or not the star is in outburst.  Time-series are *not*
required; if you are observing with a CCD, please use filters if
available and obtain a S/N of 50 or higher if you can do so in
reasonable time. Please report all observations promptly via WebObs if
possible, particularly during XMM-Newton's observing window on March
22/23 UT (JD 2454548.5).


SS Aurigae is located at RA: 06 13 22.50 , Dec: +47 44 26.0 (J2000)
