Alert Notice 750: T CrB photometry and spectroscopy requested for HST and XMM-Newton observations
Note: Ongoing observations of T CrB are extremely important as the eruption predicted for 2024 draws closer. See HERE for more information. - Elizabeth O. Waagen, July 5, 2023
Please continue to monitor T CrB until further notice. - Elizabeth O Waagen, February 9, 2023
Alert Notice 716: XMM-Newton observing five T Tau stars

Alert Notice 614 : Monitoring of GW Lib to support XMM-Newton observation
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
Alert Notice 607: MASTER OT J132104.04+560957.8 photometry urgently needed for XMM observations
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.
Alert Notice 601: V902 Mon observations needed to support XMM-Newton observation
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).
