Planning week 17 - 24 December 2016
in this plan was lost except studies on 17 December up to 18:01. The problem
is believed to be due to a single event upset (SEU) which caused an
error in the MDP. I've left the notes I originally wrote for reference.
The main thing going on this week was a set of coordinated
campaigns with ALMA, taking place between 13 and 20 UT on Sat-Sun and Tue-Thu. HOP 79
(irradiance scan) was supported on 20-21 Dec.
The week began with very low GOES activity, and a large north coronal hole rotating around the east limb. An unnumbered AR was sitting in a large island within this coronal hole, and this was the main target for OP1. A bright point rapidly expanded to a small AR (12619) on 18 December and became the default target for OP2. Another bright point emerged on 19 December and was unusual in having an "anti-Hale" magnetic configuration. This was named AR 12620 and became the default target for OP3.
I wanted to take advantage of the large coronal hole for jet
or plume studies, but I saw very little jet activity and very few
plumes, and the only study I ran was on Mon-Tue.
Saturday 17 Dec (OP 1)
As XRT was mostly in bake-out for this OP I got 34% of the DR
I ran Atlas_60 on QS near disk center at 11:10, then HOP 328 (with ALMA) was run between 12:30 and 15:30. The target was spicules at the east limb, and I just ran Cool_loop_response continuously.
The unnumbered AR had a very bright fan loop that was next to a lane of coronal hole, so I decided to run my old study PRY_footpoints_HI2 six times, spread over a 48-hour period. The times are:
17/16:16 -> with IRIS (UPDATE: this data-set was successful, all later ones were lost)
raster should include the fan loop and the coronal hole. **UPDATE: the
fan loop was significantly fainter by the time the observation started,
and continued to fade. The AR was essentially dead by the end of the
Sunday 18 Dec (OP1)
The PRY_footpoint_HI2 raster was run three times (see above).
The ALMA campaign was supported again between 18:30 and 20:00 with the target a prominence at the west limb. I thought the best study was simply an Atlas_60, which I scheduled at 18:32.
Monday 19 Dec (OP1)
No ALMA campaign today. The PRY_footpoints_HI2 was run twice (see above).
10:21 to 15:28 I scheduled Cool_loop_stare on the bright
fan loop of the AR. I also followed it with a single run of
Cool_loop_resp_v2 for some context. **This was coordinated with IRIS.**
**UPDATE: the fan loop was extremely weak by this point.**
For the period 18:15 to 09:07 (20th) I scheduled
Cool_loop_narrow for monitoring small-scale heating and dynamics in a
patch of coronal hole near disk center.**This was coordinated with
IRIS.** **This raster ended up being almost directly south of AR
Tuesday 20 Dec (OP1)
The coronal hole observation continued into the 20th.
Tuesday 20 Dec (OP2)
The small, non-flaring AR 12619 was the default target for this OP. I began with Atlas_60 at 10:53 UT, and then ran ar_evolution from 12:00 UT for 5.5 hours. This included the period for HOP 326, an AR plage study coordinated with IRIS and ALMA.
After some engineering studies, I resumed with ar_evolution from 18:20 UT for 3 hours, in support of HOP 328 (generic ALMA AR observation, with IRIS).
The 20 pointings for HOP 79 (north-south scan) began at 21:19
UT and continued to 21-Dec.
Wednesday 21 Dec (OP2)
HOP 79 continued until 11:42 UT. At 12:42 I resumed AR tracking with ar_evolution for 4 hours, as part of HOP 328 again. An AR spectral atlas was performed at 16:46 UT, and then I resumed AR tracking for the rest with ar_evolution at 18:02 (12 hours; 46 rasters).
Thursday 22 Dec (OP2)
AR 12619 tracking continued, with an additional sequence at
09:20 UT (3 hours; 12 rasters).
Thursday 22 Dec (OP 3)
Since AR 12620 was near the limb, SOT gave up a lot of the telemetry, and I got 39.%.
For this OP I tried to run the study ar_evolution on AR 12620 most of the time.
Prior to HOP 329 (ALMA) I ran ar_evolution at 11:25 (3 repeats). HOP 329 was supported on AR 12620 with the sit-and-stare study SI_Mercury_slit for four hours from 12:45. Note this study has a very high data rate.
HOP 328 (generic ALMA campaign was supported on AR 12620 with
9 repeats of ar_evolution from 17:52. AR tracking of AR 12620 then
began with 34 repeats of ar_evolution from 20:30.
Friday 23 Dec (OP 3)
The ar_evolution sequence on AR 12620 continued until 05:23 and then I followed with Atlas_60.
The next ar_evolution sequence (37 rasters) began at 06:37,
and then another one of 37 rasters began at 18:22.
Saturday 24 Dec (OP 3)
The ar_evolution sequence on AR 12620 continued until 04:03 and then I followed with Atlas_60.
The final ar_evolution sequence of 10 rasters began at 06:09.
