Planning week 7-14 September 2013

This was a quiet week, with little flaring activity. The main target in the first half of the week was AR 11838, an unremarkable AR that emerged during the previous rotation and was named AR 11818. For OPs 3 and 4 the default target became a newly emerged region AR 11839 and, after that rotated round the limb, we switched to AR 11841 on 15 September in the eastern hemisphere (however I didn't schedule any observations of AR 11841).

Due to the launch of the SPRINT-A rocket on 14 September, it was not possible to upload the EIS weekend plan on this day, so a 4 day weekend plan was uploaded on 13 September. This meant that I had to prepare an extra weekend plan for this week, so I give details of 15-17 September below. 

The HOPs that were supported were:

HOP 81 - polar monitoring campaign, supported on 8, 10 and 11 Sep.
HOP 206 - polar panorama map, supported on 7, 9, 13 and 16 Sep.
HOP 237 - spectroscopic study of magnetic tornadoes (9, 11, 12 Sep)

Note that HOPs 81 and 206 used the same EIS study and targets. There was an additional HOP 236 which was a collaboration between SST, IRIS and Hinode, but I didn't support this specifically as we didn't receive pointing information in time for the Hinode plans.

A low latitude coronal hole was present during the planning week, and I got an observation on 11 September.

At the time of this week's plan, the EIS team are experimenting with the implementation of pointing offsets in order to get better alignment with AIA and IRIS. For targets selected from AIA images, I thus manually adjusted the EIS X-position by -17 arcsec. (The Y-offset is -3 arcsec, so was not worth correcting for.)

Saturday 7 September (OP 1)

I requested an extended stay at disk center for the 18:00 synoptic so that I could take a spectral atlas (Atlas_60). Within the FOV there was a small, intense bright point but it had disappeared by the time the observation took place.

The default target for the weekend plan was AR 11838, and I decided to just to schedule four Atlas_60 studies spread over the 3 day plan. The first of these was at 19:18 on the 7th.

Sunday 8 September (OP1)

AIA 193 image

The second Atlas_60 for AR 11838 was scheduled for 07:13.

HOP 81 was run at the north pole from 08:47 to 13:45. The main study is a single run of SK_CH_DIAG_320x384, and I put PRY_slot_context at either end.

Monday 9 September (OP 1)

The third Atlas_60 for AR 11838 was scheduled for 01:19.

The first support of HOP 237 was scheduled for 03:34 to 09:20. It consists of eis_tornadoes_sns, book-ended by eis_tornadoes_scan. The pointing was a prominence at the NW limb. Based on the 193 image, the prominence was small and we probably missed it with EIS.

HOP 206 (which is basically identical to HOP 81) was supported from 09:26 to 14:17.

The fourth Atlas_60 for AR 11838 was scheduled at 19:44.

Tuesday 10 September (OP 2)

AIA 193 image

HOP 81 is supported from 10:19 to 15:10 (north pole).

For this OP I am continuing to run spectral atlas studies for AR 11838. The first of two is at 18:48.

Wednesday 11 September (OP 2)

AIA 193 image

There's a low latitude coronal hole that's crossing the central meridian during 11-12 September. The west end of the coronal hole has a nice set of plumes so I requested a 3 hour observation from 00:00. I run PRY_CH_density at 00:05 in order to get a decent density measurement in one of the plumes, and I then run Large_CH_Map at 01:08 to get a good map of the plumes, including the quiet Sun north of the hole. The final observation has two main plume features: one that's almost side on, pointing into the hole, and another at the edge of the hole where we seem to be looking along the plume's axis.

HOP 237 is supported again for the period 02:30 to 08:16, with a prominence close to the west equator. The Hinode pointing changes at 08:00 so it's possible that the pointing may change during the last HOP 237 raster.

HOP 81 was supported again, this time at the south pole, from 10:30 to 15:30.

The second Atlas_60 study on AR 11838 (see 10 Sep) was scheduled for 19:23.

I had some data volume to burn so I scheduled Hunter_loop_fe8 at 21:55 to search for a bright loop footpoint from the AR complex that includes AR 11838. Although the trigger worked, the selected region is not very good, showing just weak emission in Fe VIII, so something must have gone wrong.

Thursday 12 September (OP 2)

HOP 237 is supported again from 02:30 to 08:00. A mistake occurred when we switched from a fixed pointing at the limb to an on-disk pointing: tracking was not switched on. I adjusted the raster positions to compensate.

Thursday 12 September (OP 3)

Note that for OP3 XRT was mostly in bakeout, so I was given 25% of the DR allocation. This allowed me to plan more studies.

For OP3 the default AR pointing switched to AR 11839, a small, recently emerged region to the west of 11838. I scheduled an ATLAS_60 study at 11:05 and it may be useful for studying abundances.

From 18:30 I scheduled IUU_SCAN_STEPS_002 for 6 hours on AR 11839. There should be some overlap with IRIS and BBSO for this data-set.

Friday 13 September (OP 3)

HOP 237 was supported again from 03:30 to 08:00, this time for a prominence at the NW limb.

Friday 13 September (OP 4)

AIA 193 image

The Friday plan had originally been part of OP 3, when the EIS DR allocation was 25%. When it was switched to OP 4, I didn't change the plan which meant that it used up most of the telemetry of the 4 day weekend plan (since the 4 day plan went back to 15%).

HOP 206 was supported again from 10:25 to 15:16 at the north pole.

A second ATLAS_60 study for AR 11839 was scheduled for 17:20, and then IUU_SCAN_STEPS_002 was run again for 5.5 hours from 18:55.

Saturday 14 September (OP 4)

AIA 193 image

HOP 237 was supported for the last time this week from 03:00 to 07:44. The target is a small filament at the NW limb - this one may actually be a "tornado".

HOP 236 was supported with an Atlas_60 at disk center (quiet Sun) at 09:13-10:18. This should be coordinated with IRIS.

A third ATLAS_60 study for AR 11839 was scheduled for 17:58.

Sunday 15 September (OP 4)

AIA 193 image

The only science observation for this day is another ATLAS_60 study for AR 11839, scheduled for 15:13.

Monday 16 September (OP 4)

HOP 206 was supported again from 10:32 (north pole).

Tuesday 17 September (OP 4)

No observations this day.
