Planning week 14-21 November 2015

The week began with low solar activity, and AR 12449 (actually a large complex with AR 12450) being the default target, although not producing any flares. For OP2 we switched the default pointing to a large fan loop footpoint complex belonging to AR 12554. OP3 was dominated by calibration and engineering tests related to the EIS bakeout (which will happen in the following week) and so no science studies were possible.

HOP 237 was scheduled for this week, the target being solar tornadoes close to the limb.

Don Schmitt was the IRIS planner for OP1, and Hans Courier the planner for OPs 2 and 3. There was no coordination during OP1 as the Sun was not very interesting, but I did try coordination during OP2.

Interesting studies for me were:

Saturday 14 Nov (OP 1)

I front-loaded the weekend plan, putting most of the studies in the first 24 hours. I didn't bother trying to coordinate with IRIS as the targets weren't very interesting.

At 11:01 I ran cam_ar_limb_lite_v2 at an AR at the SE limb. It wasn't active at the time of planning.

At 14:05 I scheduled HOP021VEL360x512v1_b to make a large raster scan of the the 12449/12450 complex.

A large fan loop brightened during the time of planning in the AR complex, so I scheduled two footpoint studies for it. Cool_loop_resp_v2 was run at 18:23 (30 repeats). **UPDATE: by the time it was observed, the footpoint had dimmed and it had a fragmentary structure.**

The footpoint study continued at 02:23 with 3 repeats of Cool_loop_stare. Since the footpoint is far from the satellite pointing I had to make an estimate of the change in geometry from planning to observation.

HOP 237 began at 06:18 with the eis_tornadoes studies. At the time of planning there was a small tornado-like feature approaching the SW limb.

HOP 237 was run again at 07:02 on the same target.

Tuesday 17 Nov (OP1)

Atlas_120 was run on the quiet Sun at (0,+800) at 03:05.

Tuesday 17 Nov (OP2)

[I may have messed up OP2 and loaded the draft plan instead of the final plan. The text below describes the final plan.]

I requested an observation of a coronal hole plume during 11-18 UT. The equatorial coronal hole was narrow, but there were two bright plumes inside it, so I selected one. I chose Cool_loop_stare for 11:13-14:17, and then Cool_loop_narrow for 14:21-16:10. I requested IRIS support. [**UPDATE: the plume was bright and stable during this period. Check]

HOP 79 was supported during 20:05 to 00:30.

Wednesday 18 Nov (OP 2)

The big fan loop footpoint structure was crossing the central meridian from 18:00 onwards, so I scheduled Large_CH_Map at 18:23, and then 19 repeats of Cool_loop_resp_v2 at 19:28. I requested IRIS support. [**UPDATE: the footpoint region showed interesting evolution immediately prior to this observation, as it responded to some nearby emerging flux. It was particularly bright at the start of the observation. See for more details.]

Thursday 19 Nov (OP 3)

Three studies were run in preparation for the bakeout test: HPW023_FULLCCD_V2 (sit-and-stare at limb) at 10:12; Atlas_120 on quiet Sun at 11:14 and Atlas_60 on AR 12454 at 13:25. There then followed some pointings for HOP 79.

Friday 20 Nov (OP 3)

HOP 79 continued into Friday, but there were no science observations this day.

Saturday 21 Nov (OP 3)

No science observations this day.
