Alert Notice 322: Multicolor CCD campaign for AM Her to support XMM Newton observations AND BP Hyi eclipsing binary campaign

July 14, 2005

SUBJECT:
1. MULTICOLOR CCD CAMPAIGN FOR AM HER TO SUPPORT XMM NEWTON OBSERVATIONS
2. BP HYI ECLIPSING BINARY CAMPAIGN


1. MULTICOLOR CCD CAMPAIGN FOR AM HER TO SUPPORT XMM NEWTON OBSERVATIONS

Summary
The polar AM Her is going to be observed with the XMM Newton satellite observatory later this month. We have been asked to coordinate multicolor CCD ground based photometry during the observing periods.

Alert Notice 332: Request to monitor V426 Oph for XMM Newton observations

January 18, 2006

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)

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.

Alert Notice 488: Observations of AA Tau requested to schedule XMM-Newton

August 1, 2013: Dr. Hans Moritz Guenther (Harvard-Smithsonian Center for Astrophysics) has requested nightly observations of the classical T Tauri star AA Tau in order to schedule x-ray observations with XMM-Newton that have been planned for between 2013 August 15 and September 15.
