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. ivo://sot.lmsal.com/VOEvent#2007-05-09T00:00:00Z
