SUBJECT: REQUEST TO MONITOR V426 OPH FOR XMM-NEWTON OBSERVATIONS
Dr. Darren Baskill, University of Leicester, has requested optical observations of the cataclysmic variable star V426 Oph to coincide with upcoming XMM-Newton observations.
1803+05 V426 Oph is located at RA: 18:07:51.7 and Decl.: +05:51:48. (J2000)
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.
