Tohban report, 6-Jul-2006 to 12-Jul-2006 Albert Y. Shih, ayshih@ssl.berkeley.edu 1. Solar Activity Active region 10898 produced an M-class flare that RHESSI observed with excellent coverage. Solar activity has otherwise been decreasing steadily. How many GOES flares occurred? Flares above B, C, M, X class were 39 5 1 0 And how many of these are listed in the RHESSI flare list? Flares above B, C, M, X class were 15 3 1 0 And how many had EXCELLENT coverage? Flares above B, C, M, X class were 9 1 1 0 There were RHESSI flares/GOES flares 49 / 45 over the time range 04-Jul-06 11-Jul-06 2. Memory Managment Due to the failure of the BGS "cross-elevation" system, RHESSI data could only be retrieved through Wallops and Weilheim. As a consequence, the decimation scheme was increased to active/vigorous on July 10 at 09:26:51 UT. The PMT collection was reduced to 2 Hz from 4 Hz. 3. Data Gaps Data seems to be somewhat "spiky" occasionally.

Spacecraft Operations It is presently unclear what the problem is with BGS. Stay tuned. In other news, the voltage on detector 8 was decreased by 6 counts. 5.
