AAVSO Special Notice #99: Campaign in support of SS Aurigae observations by XMM-Newton delayed

March 10, 2008: Further to AAVSO Alert Notice 371, we have been informed by Dr. Patrick Godon that XMM-Newton observations of the dwarf nova SS Aurigae have been delayed by the XMM-Newton Science Operations Center. They have not been issued a new date, and so the request for observations in Alert Notice 371 is now cancelled.
Please observe SS Aurigae as part of your normal observing program if you already do so, but increased coverage is not yet required.

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.
