In middle of split (by perigee passage) TOO observation of 'SS CYG' (obsid's 2307-pre-perigee and 648-post-perigee). The perigee passage is, as usual, bounded by ACIS CTI measurements plus a bias measurement in squeegy mode prior to the inbound CTI.

Bill's message from the morning still true: ACE proton levels are in the 2000-6000 range now and another CME is expected to reach earth tomorrow. However, HETG is in and should protect us from all but the most severe storms.
