Planning week 30 March - 6 April 2024This is a standard planning week, with three OPs. The week includes a PSP perihelion pass on 30 March and a Solar Orbiter perihelion pass during 27 March to 10 April (remote sensing window 14). PSP is on the Earth-Sun line on 30 March for the perihelion pass. Solar Orbiter begins at an angle of 45 degrees (i.e., solar-west from Earth-Sun line) on 30 March and moves to an angle of 90 degrees on 7 April. At the beginning of the week the default target was AR 13615, which had produced a lot of flares but was at the west limb. In OP2 the default AR was switched to AR13622 although there wasn't much activity. For OP3 a large sunspot was just appearing over the east limb and this became the default target. There are multiple HOPs this week due to PSP and Solar Orbiter coordination.
Saturday 30 Mar [OP1]The plan began with HOP 393 (Large_CH_Map) at 11:26 UT. HOP 409 (joint with PSP) was supported with FlareResponse01 at 14:37 UT (20 repeats) and 18:10 UT (35 repeats). I then scheduled Flare266_Hunter01 at 23:50 UT for four hours with the XRT flare flag and the response was FlareResponse01. (I did this because I didn't have enough telemetry to run FlareResponse01 continuously). The target is AR 13615, and I off-pointed to be mostly off-limb. [UPDATE: an X-flare occurred at about 21:10 UT! This should be captured by EIS.] Sunday 31 Mar [OP1]HOP 478 was supported with 5 repeats of CH_bound_24x512v1 beginning at 09:33 UT. The target is a coronal hole in the SW quadrant. Monday 1 Apr [OP1]HOP 478 was supported with 7 repeats of CH_bound_24x512v1 beginning at 06:12 UT. The target is a coronal hole near disk center (different from 31 March). Tuesday 2 Apr [OP1]No studies. Tuesday 2 Apr [OP2]HOP 478 was continued with 3 rasters beginning at 12:30 UT, and a fourth at 18:11 UT. The target was the same as 1 April. Wednesday 3 Apr [OP2]HOP 478 was continued with 7 rasters beginning at 05:41 UT. The target was the same as 1 April. Thursday 4 Apr [OP2]HOP 457 was supported with Atlas_60 at 04:50 UT, followed by CLASP-1_60x512_OBS_ at 06:14 UT (5 repeats) and 09:15 UT (3 repeats). This sequence was broken by an XRT synoptic and the EIS table upload. Thursday 4 Apr [OP3]HOP 457 was continued with 6 repeats of CLASP-1_60x512_OBS_ at 11:31 UT followed by Atlas_60. Pointing is at limb. HPW021VEL260x512v2 was run at 18:52 UT followed by Atlas_60 at 20:31 UT. These are regular AR studies and the target was the sunspot near the east limb (unnumbered AR). Friday 5 Apr [OP3]I took advantage of HOP 349 to do a quiet Sun spectral atlas (Atlas_60) at disk center, beginning 04:15 UT. As the large sunspot has bright loop footpoints, I scheduled Cool_loop_response at 10:49 UT with 20 repeats. [UPDATE: the footpoint ended up at the far-right of the raster and didn't look particularly interesting.] Saturday 6 Apr [OP3]HOP 393 was supported at 00:12 UT with Large_CH_Map_v2.
