RHESSI Tohban report, 6-Jun-06 to 13-Jun-06 Hugh Hudson, hhudson@ssl.berkeley.edu 1. Solar Activity Activity was low: How many GOES flares occurred? Flares above B, C, M, X class were 20 0 0 0 And how many of these are listed in the RHESSI flare list? Flares above B, C, M, X class were 5 0 0 0 And how many had EXCELLENT coverage? Flares above B, C, M, X class were 5 0 0 0 There were RHESSI flares/GOES flares 25 / 20 over the time range 06-Jun-06 13-Jun-06 2. Memory management SSR at 0% after the BGS passes, rising to about 10-15% 3. Data gaps No significant gaps 4. QL survey * A couple of G4 glitches, e.g. 9-jun 02:42 * A spike not appearing in the monitor rates, 9-jun 08:01 * Flare seen while offpointed: 10-jun 16:35 * Egregious flare-finder failure: 11-jun 18:31 (cf 13-jun 16:45) 5. Crab Nebula Crab offpointing started 9-Jun and we got to within half a degree of the target in four days. It was a smooth operation; the Hurford and Fivian software worked excellently. Bryna Hazelton (UCSC) served as lead observer. Two erroneous commands resulting from the observers not really understanding the software occurred; this probably slowed us down by one day. RHESSI at best can only slowly go faster than the Sun does, at least in our one-orbit-at-a-time commanding mode. The unexplained overnight drifts of RHESSI pointing are large now (about half a degree and consistent in direction) and we will probably have to be touching up the pointing in fugure days. For the offpoint the special Crab decimation table is being used. The shutters are disabled and front segments are taking data at night. The SAS limb data is off. 6. Next Tohban: H. Hudson
