Ishibashi, B 0 Active region tracking across disk AR AR, SS 10953 2 924.84 -200.16 2113.54 2113.54 2007-05-08T10:02:08.000Z 2007-05-08T23:59:43.000Z 924.84 -200.16 CDS/UVCS + Ulysses Campaign AR_on_disk_1 Tim File-OBS_DEC: AR - Microflares and Topology - Ti/Poly, Thick-Al, Thick-Be pairs, G-band - contexts + 512 - high cadence; Daily Note: 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.; Request to XRT HOP Number 0007: ; Other Instruments: SoHO/CDS, UVCS; SoHO keyhole starts 17-May (26m dish) and 21-May (34m dish) STEREO/SECCHI Ulysses will be ending the quadrature with SOHO. Ulysses will be at a latitude of 55 deg (south-west), in the plane of the sky. Hence any active region say between 45 and 65 degree south that might be near the limb would contribute to the solar wind measured in-situ by Ulysses. Scintillation measurement (G. Poletto); Scientific Objectives: The main aim is to measure chemical abundances in active regions as a function of height for 1.0 andlt; R(Sun) andlt; 1.6 using SOHO/CDS, Hinode/EIS, SOHO/UVCS, and to link them with in-situ measurements by Ulysses. A secondary aim is to measure electron temperatures, densities, and ionization state of the plasma as function of height from 1.0 to 1.6 solar radii using SOHO/CDS and Hinode/EIS. There have been no previous spectroscopic observations in the range 1.2 and;#8211; 1.6 R(Sun). ivo://sot.lmsal.com/VOEvent#2007-05-08T09:59:54Z
