RHESSI Tohban report, 08-Feb-2006 to 15-Feb-2006 Cyril Dauphin, cyril.dauphin@obspm.fr Firstly, thanks to Pascal Saint-Hilaire for useful comments on RHESSI. 1. Solar Activity Activity has been extremely low with a background about A0 level most of the time. The flare-counting software hsi_tohban_flare_counter.pro does not work for this week. Region 10853 produced a B1 flare observed by RHESSI on the 8th. 2. Memory Management: Memory has not been a problem due to low activity. SSR fill level hovered the whole week around 20-25%, which is relatively high in respect to decimation state (see below) and solar activity. 3. Data gaps Only a small gap appears on the 8th: 2006-02-08T07:35:00.000 -- 2006-02-08T07:40:00.000 300.00000 4. Decimation, Shutter issue Decimation stayed at Normal/Vigorous. Attenuator stayed at A0 almost all week except some changes to state A1 might be due to RHESSI transit through the regions of high geomagnetic latitudes or to the proximity of the SAA. An unexplained switch to A1 occured on the 9th around 20:40 UT, and lasted several hours. 5. Next Tohban: Martin Fivian
