 Planning Notes - Weekend Activities

Main | Weekend | Flexible | Synoptic | Notices

The weekend programme involves a set of high-priority, long-duration observations which are run over many weeks at weekends. The content of this programme changes periodically. The current items which are run each weekend are given below. An example schedule for them is the following;

  • Saturday:
    • 00:00-07:00 - Synoptic scan (SYNOP_F)
    • 07:00-18:30 - CDS Limb Active Region Studies
    • 18:30-24:00 - Off-Limb Spectral Study (part 1: North)

  • Sunday:
    • 00:00-07:00 - Synoptic scan (SYNOP_F)
    • 07:00-12:30 - Off-Limb Spectral Study (part 2: South)
    • 12:30-24:00 - CME Onset Study

Other options include simply running only one of the studies (e.g., CME onset or active region) all weekend, together with SYNOP_F.

Title CDS OFF-LIMB CORONAL STUDY (N-S)
Dates To be run once every weekend either side of the Sunday SYNOP
Contact Andrzej Fludra - a.fludra@rl.ac.uk
Activity Off limb spectral monitoring study
Studies Run STRE4W (Study ID 11, Var. 111) once at each of the following locations:
  • North Pole; 
    1. x,y = +110,+1040
    2. x,y = -110,+1040
    3. x,y =    0,+880
  • South Pole; 
    1. x,y = +110,-1040
    2. x,y = -110,-1040
    3. x,y =    0,-880
Duration Total duration about 2 x 5h6m. TOTAL = 10.2 hours.
Notes
  1. Since these are on opposite poles, pointing movements could be minimised by running the N and S components either side of other Studies
  2. If the full 5 hours is not available, then the planner can run just the first two rasters (Y = +/-1040)

Title Polar Coronal Hole Tornadoes
Dates TOO
Contact Olav Kjeldseth-Moe (olavm@astro.uio.no) / Danielle Bewsher (d.bewsher@rl.ac.uk)
Activity Detect tornadoes at the polar regions
Studies O_LOOP6 (Study ID 113, Study Var 6)
Duration Minimum 2 hours, but raster can be repeated to fill available time slot.
Pointing Raster should be pointed at the best polar coronal hole visible. X = 0, and Y = +/- 940 depending on which pole observed

Title CDS LIMB ACTIVE REGION STUDIES
Dates Regular weekend study
Contact H. Mason (h.e.mason@damtp.cam.ac.uk), P. Young, Giulio Del Zanna
Activity The objective of this study is to detect microflare bursts in the high temperature emission from FeXIX. The aim is to obtain a long time sequence (several hours) of high cadence observations for one slit position (cb_44) in an active region, just above the limb, and to allow the AR to rotate underneath the slit. A context raster should be performed from time to time
Studies CB_44/v1 (duration: 30mins); SIG_FT44/v82 (duration: 25mins)
Duration Sequence should be repeated to fill the available time slot (at least 10 hours)
Pointing Slit should be positioned around 20 arcsec above the solar limb for the CB_44 study. The pointing for SIG_FT44 should be 60 arcsec further from the limb than CB_44
Sequence Begin with a single run of SIG_FT44, followed by 8 repeats of CB_44. These should then be repeated to fill the available time slot, finishing off with a single run of SIG_FT44

Title CME ONSET WATCH
Dates To be run for 10 hours minimum if a promising target available.
Contact Richard Harrison - r.harrison@rl.ac.uk.
Activity To be run in three 4x4 arcmin mosaic forming a 4x12 arcmin field on west or east limb, to monitor limb over a number of hours. See, e.g. run 15379 on 19-Dec-1998. Target limb should be above a prominence/filament or active region near the limb. See 19-Dec-1998 run for pointing.
Studies EJECT_V3 (Study ID 11, Var. 18) - 15m53s cadence/raster, i.e. about 45m cadence per 12x4 image
Duration Minimum of 10 hours
Pointing -
Notes MK_PLAN settings - number of pointings =3, repeat raster = 1, repeat plan = N (where N fills the available time)

Title AR/FLARE DIAGNOSTICS - this study replaces the Explosive Event Monitor when an active region target is available
Dates To be run during weekend programme when target is available. The HIGHEST PRIORITY is to observe the same AR jointly with TRACE. A recommended target is an active small/medium active region
Contact Helen Mason - h.e.mason@damtp.cam.ac.uk, Giulio Del Zanna - gdz@mssl.ucl.ac.uk
Activity to be run when there is a small/medium AR which has shown recent activity or is predicted to be active. If there is a choice or regions choose one which best fits in the 4x4 arcmin field. If possible repeat on the same region as a previous run.
Studies ARDIAG_2 (ID 11, var 92) and SIG_FT44 (ID 11, var. 82)
Sequence Run ARDIAG_2 (ID 11, var 92 - duration 1h 23m), followed by at least 6 repeats of SIG_FT44 (ID 11, var. 82 - duration 25m each) and ARDIAG_2 again.
Duration DURATION: 6-8 HOURS
Pointing Move as infrequently as possible to follow solar rotation but so that any cumulative rotation offsets are kept below 20 arcsec from the initial ARDIAG_2 run

Title EXPLOSIVE EVENT MONITOR - run only when no active region available for the AR/FLARE DIAGNOSTIC study
Dates To be run once every weekend for 8 hours minimum
Contact Helen Mason (h.e.mason@damtp.cam.ac.uk)
Activity Search for velocity events in the coronal regions
Studies Run series of EE_SEEK rasters (Study ID 11, Variation 55)
Duration 8 HOURS MINIMUM
Pointing Point to central meridian, preferably at coronal hole region (if available! - otherwise quiet Sun)
