Schedule of monitoring observations in the X-rays (PI: Wijnands, unless
otherwise noted):
Chandra HRC on the inner 1.7 square degrees. Status: already taken 2005 June 5.
Chandra HRC on the inner 1.7 square degrees. Taken 2005 October 17-24. Reduction is in progress.
XMM Newton on the inner 1.7 square degrees. Taken February 27, 2006.
XMM Newton on the inner 1.7 square degrees. Scheduled for early April 2006.
Chandra ACIS on the inner 10 arcminutes around Sgr A*: 10 ks snapshots planned to occur every few months throughout 2006 (PI: Baganoff). Tentative schedule:
Week of 2006 May 1 (35 ks)
Week of 2006 May 29 (5 ks)
Week of 2006 July 3 (5 ks)
Week of 2006 July 24 (5 ks)
Week of 2006 Septermber 25 (5 ks)
Week of 2006 October 23 (5 ks)
Chandra ACIS large project. Should be taken in summer 2006. We will distribute
a catalog of new point sources within a week of receiving the data.

Allen Telescope Array: When not looking for Aliens, G. Bower will look for transients. It will operate at 0.5-11.2 GHz, and should come online in mid-2006.
Follow-up programs:
X-ray transient (2005): I think Rudy has a VLA and Chandra project for this. Rudy, can you remind me of the details?
X-ray transient (2006): Chandra on one transient, to monitor the flux with 5
observations of 5 ks each (PI: Wijnands).
X-ray transient (2006): VLA on one transient with a 2 hr observations to
establish a detection, and 5 observation of 2 hrs each if it is worth
following up (PI: Wijnands).
Radio transient (2006): Chandra on one radio transient for 50 ks, plus 4
observations of 5 ks each if it is detected (PI: Wijnands).
Radio transient (2006): A VLA proposal was submitted for Oct 1 to follow up
on GCRT J1745-3009 (PI: Hyman). They plan to submit further proposals.
X-ray transient (2005-2006): I am assuming that Z. Wang will continue to
obtain Magellan observations to look for infrared counterparts to transients.
