RHESSI Tohban report, 29-dec-2003 to 5-jan-2004 J.McTiernan, jimm@ssl.berkeley.edu Happy New Year 1. Solar Activity: The first two days were very quiet, the background GOES level at approximately B3. Activity picked up with the arrival of NOAA 0536, includng an M6.9 flare at approx. 0250 UT on 5-jan 2004. RHESSI should have seen at least the first 25-27 minutes of this one. How many GOES flares occurred? Flares above B, C, M, X class were 28 23 1 0 And how many had good RHESSI coverage? Flares above B, C, M, X class were 9 7 1 0 And how many are listed in the RHESSI flare_list? Flares above B, C, M, X class were 10 7 1 0 How many RHESSI flares: 62 These data are incomplete; the flare list after 1-jan-2004 has not yet been processed. 2. Memory Managment: Decimation was normal/normal (IDPU version 12) for the entire week. (You can obtain the IDPU version using the hsi_obs_summ_flag object: e.g., o = obj_new('hsi_obs_summ_flag') oti = anytim(['29-dec-2003 0:00','5-jan-2004 0:00']) d = o -> getdata(obs_time_i = oti) ppp = o -> get(flag_name = 'idpu_control') Or to plot o -> plot, flag_name = 'idpu_control' Then see http://sprg.ssl.berkeley.edu/~tohban/conversion.txt for the conversion.) The SSR fill level was 65% at the start of today's passes, due to the M flare, so it might be a good idea to increase decimation. Average SSR fill %: 2003/12/29 9.32068 2003/12/30 12.8398 2003/12/31 12.0777 2004/01/01 35.7968 2004/01/02 35.2682 2004/01/03 31.2025 3. Data Gaps: VC3 Gaps ============================================================================== Start Time (GMT) End Time Duration (sec) ------------------------------------------------------------------------------ 2003-12-30 18:30:00.000 2003-12-30 19:50:00.000 4800.0000 2004-01-01 18:35:00.000 2004-01-01 20:20:00.000 6300.0000 2004-01-02 00:45:00.000 2004-01-02 00:50:00.000 <300.00000 2004-01-02 03:00:00.000 2004-01-02 03:05:00.000 <300.00000 ------------------------------------------------------------------------------ The first is between a BGS and WPS contact. The second is almost certainly due to sunny being down during the first BGS contact on 2-jan-2004. this will be recovered later today. The last two represent the loss of 3 monitor rate packets, due to noisy data. VC1 Gaps ============================================================================== Start Time (GMT) End Time Duration (sec) ------------------------------------------------------------------------------ 2004-01-02 05:00:00.000 2004-01-02T20:35:00.000 56100.000 2004-01-02 22:15:00.000 2004-01-02T22:30:00.000 900.00000 ------------------------------------------------------------------------------ The first gap is due to the missing contact from 2-jan-2004, this will be reprocessed. The second is between two BGS contacts, files vc1_20040102220514.0 and vc1_20040102234604.0. 4. Cryocooler: ICP1T, the cold plate monitor #1 temperature, is now hovering in the 85 K range.
