February 12, 2018: Dr. Koji Mukai (NASA Goddard Space Flight Center) and colleagues have requested AAVSO observations of the WZ Sge type dwarf nova GW Lib in support of observations with the ESA XMM-Newton spaceobservatory scheduled for
2018 February 17 05:46:41 - 21:36:41 UT
December 1, 2017: Dr. Mark Kennedy (Jodrell Bank Centre for Astrophysics, University of Manchester) requests AAVSO observers' assistance in providing optical coverage of the polar MASTER OT J132104.04+560957.8 in support of observations with the XMM-Newton satellite scheduled for this Sunday, 2017 December 3, 08:35:31 UT - 16:38:51 UT.
The XMM-Newton observations themselves will not include an optical component, so photometry provided by AAVSO observers is essential for the interpretation of the X-ray data.
October 10, 2017: Dr. Hauke Wörpel (Leibniz-Institut für Astrophysik Potsdam (AIP)) has requested AAVSO assistance in obtaining observations of the eclipsing intermediate polar (IP) candidate V902 Mon in support of an XMM-Newton observation scheduled for 2017 October 14, 14:42 UT (duration 43,000s).
April 6, 2017 : Dr. Nicolas Grosso (CNRS, Observatoire Astronomique de Strasbourg) has requested AAVSO assistance in monitoring the young eruptive star (FUOR type) V2492 Cyg from the optical to the infrared in support of X-ray observations with XMM-Newton scheduled for 2017 April 18 UT.
The XMM observations will take place: 2017-04-18 03:27:07 UT - 2017-04-18 14:17:07 UT.
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.
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.
