RHESSI Tohban report, 02-Feb-2006 to 08-Feb-2006 Iain Hannah, hannah@ssl.berkeley.edu Firstly, Happy Birthday RHESSI. 1. Solar Activity Activity was extremely low all week with the background flatlining about A0.3 level most of the time, which was good since we were offpointing for part of the week (see below). From about 04-Feb some big hot loops came around the east limb which have resulted in 6 little flares of which we caught 2 of them: 04-Feb-2006 20:00 A6 (during offpoint) 08-Feb-2006 21:15 B1 Unlikely to get much more than these hiccups for the next week unless something emerges onto the disk. 2. Memory Management: Memory held steady ending the week at 24%: started the week at 24%, dropping to 16% before starting the offpointing/SAS. 3. Data gaps Only appears to be 2 of merit/concern, one on the 3rd and 4th: 2006-02-03T13:45:00.000 -- 2006-02-03T15:35:00.000 6600.0000 2006-02-04T01:35:00.000 -- 2006-02-04T01:50:00.000 900.00000 4. Decimation Decimation stayed at Quiet/Vigorous during the offpointing and was changed to Normal/Vigorous when we "returned" to the Sun (about 16:00UT 06-Feb) 5. Offpoiinting/SAS & then Spun Up Started offpointing (deimation change,increased SAS, shutter logic disabled) 19:26UT on 1-Feb and then command to return to the sun was sent 15:54UT 6-Feb. However due to the low spin rate, went into idle mode. After an initial spin up the sun was re-aquired and back to normal pointing. This occured 16:40UT on 7-Feb. Plus another spin up at 7:52UT 8-Feb to get us up to 15rpm. 6. Other things MOSES launched at 18:44 UT 8-Feb but RHESSI was in night. 6. Next Tohban: Cyril Dauphin
