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.
