Planning week 29 Apr - 5 May 2023This was a regular planning week, taking place during the eclipse season. The week began with a complex of ARs 13285, 13286 and 13288 about midway towards the west limb. They were producing C-flares with an occasional M-flare, mainly related to 13288. AR 13289 was approaching the central meridian and showing some flare activity. AR 13293 appeared over east limb at the weekend, and produced several flares. AR 13288 was the default AR target for OP1, although I didn't schedule any observations. 13293 was the default AR target for OP2. A major flare watch on AR 13293 was declared prior to OP3, so this remained the default AR pointing for OP3. Saturday 29 April (OP1)The full Sun spectral scan began today at 10:59 UT. This consists of multiple pointings of DHB_007. Sunday 30 April (OP1)The full Sun spectral scan continued through Sunday. I inserted REGCAL081/082 (dark exposures) at 12:50 UT. Monday 1 May (OP1)The full Sun spectral scan completed at 05:00 UT. AR 13289 was crossing the central meridian, so I scheduled HPW021VEL260x512v2 at 23:40 UT. UPDATE: there were some small microflares during this period. Tuesday 2 May (OP1)AR 13289 was observed again with PRY_slot_context_v4, scheduled at 01:14 UT, followed by Atlas_60. UPDATE: may have a caught a smallish flare, especially the context raster. Tuesday 2 May (OP2)I scheduled HPW021_VEL001x512v2 for three orbits at 19:27, 21:04 and 22:41 UT. This is a sit-and-stare study intended for measuring abundances in flares and AR core loops. The target is AR 13293. Wednesday 3 May (OP2)The HPW021_VEL001x512v2 study was continued with another raster at 00:15 UT. HOP 401 (dynamics on an AR neutral line) was scheduled at 08:21 UT with HH_AR+FLR_RAST_N03J followed by 16 repeats of HH_Flare_60x152f. This was joint with IRIS and SST and the target was AR 13293. UPDATE: this may have a caught of burst of flaring activity in 13293. The EVE calibration rocket was due for launch at 18:10 UT and, as part of the support, HOP 130 was run between 18:00 UT and 02:00 UT. Thursday 4 May (OP2)HOP 130 was continued until 02:00 UT. The Hinode alignment program was run at 02:25 UT (north) and 06:02 UT (east). HOP 401 was run again on AR 13293 at 08:02, 08:56 and 09:18 UT. I had to break this up due to an eclipse and the EIS table upload. UPDATE: there was an M6 flare that peaked at about 08:40. Thursday 4 May (OP3)PRY_slot_context_v4 is a new version of the venerable slot context raster, and I scheduled it for 17 repeats for the orbit beginning 12:13 UT on AR 13293. The flare study HH_Flare_raster_v6 was run on AR 13293 for four orbits, beginning at 13:52 UT, 15:30 UT, 17:10 UT and 18:52 UT. Friday 5 May (OP3)HOP 401 was supported for two orbits, beginning at 07:54 UT and 09:32 UT. The target was AR 13293. UPDATE: there was an M-flare at about 08:00 UT, but from the nearby AR 13296. I supported the flare watch with Flare_SNS_v2 for four orbits beginning at 11:10 UT, 12:48 UT, 14:26 UT and 16:05 UT. For each orbit I began with PRY_slot_context_v4. UPDATE: there were some weak microflares during this time. Saturday 6 May (OP3)HOP 393 was scheduled between 0 and 4 UT. Fortuitously, the pointing coincided with transequatorial loops extending south from AR 13293 that could be seen nicely in AIA 171 on 3 May. I adjusted the pointing a little to the right to better capture them. I scheduled Large_CH_Map at 00:18 UT and 01:57 UT. HOP 401 was supported at 08:51 UT. Again, timing was affected by the time of the EIS table upload. Page maintained by Dr Peter R Young. |
