Planning week 30 April - 7 May 2016

This planning week occurred during the Hinode eclipse season.

The week began with a number of weak active regions on the disk; AR 12535 had produced a couple of C-flares, and it was the default pointing for OP1. For OP2 and OP3 we switched to AR 12539 which was producing a few weak flares.

HOP 308 (active region filament) was supported from 1 to 7 May, and the target was AR 12539.

Note: following the recent failure of the SOT filtergraphs EIS is now receiving 23% of the DR allocation.

Interesting studies for me were:

  • Loop footpoint studies in OP1 may be interesting.
  • I ran a long series of pry_flare_2 on 4-May for about 13 hours. This was coordinated with IRIS.
  • The combined AR-CH raster on 4-May may be interesting.
  • There was a plume near disk center which I  observed on 6-May (coordinated with IRIS).

As XRT was in bake-out I got 30% of the DR allocation (4970 Mbits) which enabled a lot of studies. My focus was on the small sunspot of AR 12535 which showed some fan loops, and there were also quite a lot of transient events just to the north of the spot. I ran "cool_loop_response" for the following periods:

30-Apr 10:54-17:56 (5 orbits)
30-Apr 21:42-05:35 (5 orbits)

Each orbit had 7 rasters.

Sunday 1 May (OP1)

Atlas_60 was run for one orbit at 05:54 UT on AR 12535.

The "cool_loop_response" study on AR 12535 was continued for 5 orbits between 07:32 and 15:26 UT. The following orbit I ran Atlas_60 again at 15:44 UT.

HOP 308 was supported for 3 orbits from 17:00 UT.

During 1 May 22:21 to 2 May 02:37 I ran "IUU_SLOT_SNS_AR_001" three times again on the sunspot with the aim of looking for waves and periodic downflows.

Monday 2 May (OP1)

HOP 308 was supported for 3 orbits from 17:30 UT.

Tuesday 3 May (OP1)

Atlas_60 was run on the quiet Sun at 07:09 UT.

Tuesday 3 May (OP2)

The OP began with HOP 81 at the north pole for 12:01-16:51 UT.

HOP 308 was then supported for 3 orbits between 17:22 and 21:25 UT. The target was AR 12539.

I then ran a large AR scan of AR 12539 using GDZ_300x384_S2S3_40 at 21:52. The IRIS planner scheduled a 400-step raster for this time.

Wednesday 4 May (OP2)

From 01:08 I ran PRY_flare_2 for eight consecutive orbits until 13:57 UT. I placed it on the eastern-most footpoints of the AR, as they looked the most promising for capturing flare kernels. The IRIS planner scheduled a sit-and-stare flare study for some of this period. **UPDATE: there was no flare as such, but there was an event around 04:00 and a loop brightening around 11:00 that may be interesting.**

AR 12539 had a small coronal hole directly below it, so at 14:15 I ran my old HOP 177 study (Large_CH_map) to cover both the AR and coronal hole.

HOP 308 was supported for 3 orbits again from 17:32 to 22:01.

GDZ_300x384_S2S3_40 was run again on AR 12539 at 22:27 UT.

Thursday 5 May (OP2)

I scheduled Atlas_60 on the brightest part of AR 12539 at 00:05 UT.

Thursday 5 May (OP 3)

HOP 81 was supported again on 5 May, this time at the south pole from 10:01 to 14:51 UT. I took advantage of the south-pole pointing to schedule Harry's HPW023_fullccd_v2 sit-and-stare study from 15:01 to 16:04 UT.

HOP 308 was supported again on AR 12539 with two HPW023 rasters between 18:15 and 20:58 UT. I then ran GDZ_300x384_S2S3_40 between 21:25 and 22:39 UT on AR 12539.

Friday 6 May (OP 3)

I ran Cool_loop_response between 02:22 and 03:31 UT on AR 12539 to coincide with a dense 320-step raster done by IRIS.

There was an interesting plume close to disk center that was at the edge of an equatorial coronal hole. It may have been the remnant of an old active region. I obtained observations in 4 consecutive orbits:

10:32 Cool_loop_response (7 rasters)
12:13 cam_artb_cds_b  (sit-and-stare 40" slot, with 180 repeats)
13:51 cam_artb_cds_b  (sit-and-stare 40" slot, with 180 repeats)
15:46 Atlas_30 (I couldn't fit Atlas_60 in the time-slot)

HOP 308 was supported again on AR 12539 with three HPW023 rasters between 17:12 and 21:34 UT. I then ran GDZ_300x384_S2S3_40 between 22:00 and 23:14 UT on AR 12539.

Saturday 7 May (OP 3)

The Hinode alignment program was run during 02:56-04:02 (north pole) and 04:34-05:46 (east limb).
