SOTSP: AR/EFR study
2007-05-12T14:51:11 to 2007-05-12T16:03:00
Science Goal: Emerging Flux; AR, EFL; Active Region
Program: SP 4 cycle, 10", half height for emerging flux
Target: Active Region
xcen=257 ycen=-93
Instrument: SOTSP
HOP/JOP: 0
Description:
XRT: STEREO campaign
SOHO/UCVS-Ulysses campaign, and will do 12-filter scan during EIS cal. EIS: Calibration run over weekend. 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 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.
