The X-ray luminosity of SgrA* is expected to increase significantly at this period and the fragmentation of this cloud should lead to an enhanced activity period over several months/years. Therefore, we propose a large program to monitor SgrA* during the course of the G2 cloud near its pericenter passage and after this event, combining the XMM-Newton high-throughput with several multi-wavelength observations with ground-based telescopes and satellites. This will offer us an unique opportunity to study accretion events on a dormant SMBH and its (re-)activation process. ------------------------------------------------------------------------------------ Observations Description ------------------------ Our XMM observations will occur in 3 blocks of 53 ksec each, on Feb 27, Mar 15, and Apr 04, 2014 with the observation starts matching the VLT visibility windows of Sgr A* in Chile. Our plan is to use the 5-6 consecutive SAA-free orbits that are available each day to obtain observations over a time span of 8 hours, interrupted only by Earth occultation. We plan to obtain the WFC3/IR observations with the F153M filter. We will use the SPARS25 readout sequence, which gives us stable, equally-spaced readout intervals of 25 secs, and a total time per exposure of 5-6 minutes, which is long enough to perform WFC3 buffer dumps in parallel with the exposures, thus maximizing our on-source time. We will embed the exposures within a dither pattern in order to mitigate the effects of bad pixels, flat-field uncertainties, and persistence from bright stars. A total of 8 such exposures can be obtained in each orbit, giving us nearly constant coverage of Sgr A* over a span of about 50 minutes per orbit.
