Special Notice #425: FO Aqr XMM-Newton observations scheduled

November 9, 2016: Further to AAVSO Alert Notice 545, time series observations of the intermediate polar cataclysmic variable FO Aqr are requested to provide simultaneous coverage of XMM-Newton observations scheduled for 2016 November 13 19:43 UTC to November 14 8:13 UTC.

Special Notice #401: AM Her NuSTAR observations April 5

April 3, 2015: Further to AAVSO Alert Notice 517 (www.aavso.org/aavso-alert-notice-517), Dr. Axel Schwope (Leibniz Institute for Astrophysics Potsdam, Germany) informs us that the NuSTAR X-ray observations of AM Her will take place on

2015 April 5  15:35 UTC - April 6 19:15 UTC

These NuSTAR observations overlap with the XMM-Newton observations scheduled for April 6.

Filtered photometry with standard filter (BVRI) is requested using the cadence given in Alert Notice 517.  

Alert Notice 517: Monitoring of AM Her urgently requested in support of XMM-Newton and NuSTAR observations

April 2, 2015: Dr. Axel Schwope (Leibniz Institute for Astrophysics Potsdam, Germany) has requested AAVSO observers' assistance in monitoring the magnetic variable AM Her in support of upcoming XMM-Newton plus NuSTAR (Nuclear Spectroscopic Telescope Array) observations.

The XMM-Newton observations are scheduled for 2015 April 06 02:37:02-15:07:02 UT. The NuSTAR observations have not been made final yet but are expected to run longer. A Special Notice will be issued when the NuSTAR schedule is known.

Special Notice #197: Request for time-series photometry of U Sco

March 2, 2010: Dr. Bradley Schaefer (LSU) requests intensive time-series observations of U Scorpii beginning immediately and continuing through 2010 March 4 08:00 UT (JD 2455259.83). These observations are requested in support of coincident X-ray photometry by the XMM-Newton satellite. The XMM-Newton observations, requested by Dr. Jan-Uwe Ness (ESA), will investigate the X-ray behavior of U Sco during its transition from outburst back to quiescence.

Alert Notice 493: Request to monitor BP Tau in support of Chandra X-ray observations

December 18, 2013: Dr. Hans Moritz Guenther (Harvard-Smithsonian Center for Astrophysics) has requested nightly observations of the classical T Tauri star BP Tau in support of upcoming Chandra X-ray observations in his study of the accretion processes underway in this star.

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)
