RHESSI Tohban Report, 29-Oct-2004 to 04-Nov-2004 by Albert Shih (ayshih@ssl.berkeley.edu) 1) Solar Activity Activity has been relatively high due to active region 0691, which produced many C flares, some M flares, and one (short) X flare. Unfortunately, RHESSI was in the SAA during the X flare. AR0691 is rotating off the disk, but AR0696 has produced multiple M flares and still has a week on the disk, so activity might stay elevated for a while. How many GOES flares occurred? Flares above B, C, M, X class were 35 48 7 1 And how many of these are listed in the RHESSI flare list? Flares above B, C, M, X class were 18 32 4 0 And how many had EXCELLENT coverage? Flares above B, C, M, X class were 10 20 3 0 There were RHESSI flares/GOES flares 165 / 91 over the time range 27-Oct-04 03-Nov-04 2) Memory Management The increased solar activity filled the SSR fill level quickly, so the decimation scheme was changed on Wednesday to normal/active. (Previously, the front segments were using the modified decimation table where decimation did not begin until the fill level reached 50% as opposed to the usual 30%.) 3) Next Week's Tohban: Sam Krucker
