Alert Notice 414: Request for Observations of V405 Peg

December 17, 2009: Dr. Axel Schwope (Astrophysikalisches Institut Potsdam) requests time-series monitoring of the magnetic cataclysmic variable V405 Pegasi, beginning 2009 December 28 (JD 2455193.5) and continuing through 2009 December 30 (JD 2455196.5). These observations are requested in support of a planned XMM-Newton observation of V405 Peg on 2009 December 29 beginning at 18:51 UT (JD 2455195.2854) and continuing for 12.5 hours.

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.

Alert Notice 452: Simultaneous observations of SU Aur and AB Aur requested for XMM-Newton

8 February 2012:  Dr. Hans Moritz Guenther, Harvard-Smithsonian Center for Astrophysics, has requested bracketing and simultaneous observations in support of XMM-Newton x-ray observations of the classical T Tauri star SU Aur and the close-by Herbig Ae star AB Aur scheduled for February 15 - 17, 2012. The targets are too bright to use the XMM optical monitor for simultaneous monitoring, so your observing assistance is essential for correlation of the x-ray data.
