RHESSI Tohban Report, July 21 to July 28, 2003 Martin Fivian, mfivian@ssl.berkeley.edu 1. Solar Activity Although there was low solar activity with a GOES baselevel going down to B2, about 40 C-class flares occured. Roughly two third has been observed by RHESSI. How many GOES flares occurred? Flares above C, M, X class were 39 0 0 And how many had good RHESSI coverage? Flares above C, M, X class were 23 0 0 And how many are listed in the RHESSI flare_list? Flares above C, M, X class were 24 0 0 Here "good coverage" means that the entire interval, start to end by GOES definitions, had neither SAA nor orbit night. The number of GOES flares with RHESSI coverage and the number of counted flares in the RHESSI flare list differs slightly due to a different flare detection algorithm. 2. Memory Management Starting the week with an end-of-day SSR level around 40%, the SSR level came gradually down to below 10%. Because of a blown fuse at the antenna, three passes were missed on Sun, July 27. These data will be replayed early this week adding an additional download of about 15%. 3. Decimation active/active for the full week. 4. Data Gaps None the tohban is aware of (see 2.) 5. Next Tohban Jim McTiernan
