AAVSO Alert Notice 373

Support for XMM-Newton Observations of SS Aurigae
March 28, 2008

(Note: This Alert Notice supercedes AAVSO Alert Notice #371, issued
March 06, 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 April 07 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 21.

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 April 07 
UT (JD 2454564 +/- 1 day).


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