Tohban report, 2005/07/25 to 2005/08/01 Pascal Saint-Hilaire (shilaire@ssl.berkeley.edu) 1) Pointing Precession to the sun was started on the 2005/07/25 23:04 UT pass. RHESSI was pointing towards the sun by the 2005/07/26 03:56 UT pass. 2) Solar Activity: Activity has picked up shortly after resuming sun-pointing. Proton flux increased also. We had several M-flares near the eastern limb where AR 0792 appeared. This AR also later produced an X-flare (2005/07/30 06:17 06:35 07:01 X1.3 2B N12E61). (RHESSI was exiting the SAA at the start of the impulsive phase.) GOES baseline level is now about B3. How many GOES flares occurred? Flares above B, C, M, X class were 21 6 3 1 And how many of these are listed in the RHESSI flare list? Flares above B, C, M, X class were 3 4 3 1 And how many had EXCELLENT coverage? Flares above B, C, M, X class were 1 2 1 0 3) Memory Management: As AR 0792 was threatening to be prolific, and given the fact that the memory was 64% full, the read pointer was moved from 2005/07/28 12:35 to 20:00 UT last Friday (those 7.5 hours of data are hence lost -- no flares higher than B5 occured during that time interval). The X-flare occured on Saturday. The SSR fill level is presently 57%, and with several active regions currently on the near-side of the Sun, another memory deletion has been proposed. 4) Data Gaps: GAP START TIME GAP END TIME GAP (SEC) 2005-07-25T22:50:00.000 -- 2005-07-25T22:55:00.000 300.00000 2005-07-28T12:35:00.000 -- 2005-07-28T20:00:00.000 26700.000 (Corresponds to the requested deletion). 5) Decimation. We're in the NORMAL/VIGOROUS mode. Front segment data are not being taken during S/C night. 6) Other issues: DECIMATION record: The following page has not been updated for some time: http://sprg.ssl.berkeley.edu/~dsmith/hessi/decimationrecord.html SOH: The following files do not exist: http://sprg.ssl.berkeley.edu/~hessiops/state-of-health/2005/016/index.html http://sprg.ssl.berkeley.edu/~hessiops/state-of-health/2005/201/index.html ...and 203 to 207, 209. 7) Next week's Tohban is: Steven Christe
