Tohban Report - 8 - 14 December 2003 Andre Csillaghy Solar Activity -------------- Solar activity was very low this week. Only two flares occurred above the C-level. How many GOES flares occurred? Flares above B, C, M, X class were 27, 2, 0, 0 And how many had good RHESSI coverage? Flares above B, C, M, X class were 9, 2, 0, 0 And how many are listed in the RHESSI flare_list? Flares above B, C, M, X class were 10, 2, 0, 0 How many RHESSI flares: 47 The most quiet period was Dec 11, 18:00 to Dec 12, 7:00, as AR #513 turned behind the limb and ARs #520,521 were still not visible on the east side. Thus it left only two active regions, 516, 517 on the west. During this period of time, there are extended periods of quiet-sun observations (GOES A7), although they were sorthened by the day-time passage through the SAA. Check for instance 11-dec, 17:55 - 18:20, 19:30-19:55, 21:05-21:30, and 22:45-23:20. Operations ---------- - Only one shutter motion. - SSR levels not an issue; under 50% most of the time; dec15 the ssr was empty (1%) - Cooler operating at ~63 watts as last week. Temperature on cold plate 1 and 2 climbing to ~82 and ~83 K, respectively. - Accelerometer average higher than 20mG, some measurements are over 25mG for longer periods of time. - One data gap: 2003-12-13T18:00:00.000 -- 2003-12-13T20:00:00.000 7200.0000
