Tohban report, 20-Apr-2006 to 26-Apr-2006 Albert Y. Shih, ayshih@ssl.berkeley.edu 1. Solar Activity Active region 10875 has produced a number of C flares and one M flare (that we unfortunately missed due to eclipse). 2. Memory Managment Memory has been under control. 3.

Spacecraft Operations On April 25, the voltages were reduced on detectors 3 (by 6 steps), 5 (by 2 steps), and 6 (by 4 steps). All detectors remain segmented, although the situation with detector 3 will probably degrade significantly as time progresses. Annealing of the detectors will be postponed until after observation of the Crab Nebula to take advantage of a segmented detector 2. 5. Next Week's Tohban: Amir Caspi (cepheid@ssl.berkeley.edu)
