Science Goal: Active region tracking; AR; AR 10953
Program: Fast Map 300
Target: AR 10953

Instrument: SOTSP
HOP/JOP: 0
Description:
SOT: AR 10953 at West limb. XRT: Active Region Observations
STEREO campaign
SOHO/UCVS-Ulysses campaign XRT: FW1 closed-loop test, near end of this OP during passes 2 and 3 on Wed. EIS: 1) UVCS-Ulysses campaign: Abundances as function of height in AR. EIS is requested to observe AR at the limb for a min of 4 hr 15 min per day on five days spanning west limb passage [7th May to disappearance of AR] 2) STEREO campaign. EIS will raster the slit across the active region on the disc and at the limb. (STEREO/SECCHI will complement with 75-second cadence 171 filtergrams, with other three wavelengths at 5-minute cadence.) [4th to 8th May] 3) Coronal dimming study. EIS will run coronal_wave_study to look for evidence of dimming following large events if activity looks likely. [As long as AR is visible] 4) After disappearance of the AR, EIS would like quiet Sun pointing near limb for: a) line broadening and diagnostics above limb b) STEREO campaign 304 high-cadence co-observations of spicules c) UVCS campaign Night entry/exit events (at the time when the sun cross the earth surface) start to appear in environment event files from 8 May. If co-alignment program (2hr for N-limb, 2hr for E-limb) was not included in the May 5-7 weekend plan, please run this program soon after disappearance of the AR. andnbsp
This run will be important for calibrating absolute heliocentric coordinate for quiet sun. Also, this program may run once every a few days, depending on the satellite temperatures and science programs.
