There were several radiation alerts issued on Aug 12, 2001.
On-board stored command sequence 107 ran at 228:0208.
These were high evegy protons following a flare on the limb.
The low energy particles arrived steadily after. ACE threshold
was violated ~229:0930.
Loads are currently stopped. Expect to restart near today's perigee
passage (229:16:12). Restart Science ~230:04 if all clear.
Average of ACIS-I CCDs (MnKa) slope 1.560e-8 CTI/day
