Uzzo ------------ UVCS Activity: UVCS in Soft Safe Configuration for SOHO Offpoint -------------- Manuever of 20 August 2002 UVCS SWMODE = SAFE as of 13:00 UT 20 August 2002 due to SOHO OFFPOINT (FLTERR = Y SUN CEN UNSAFE) Recovery of UVCS from Soft Safe Configuration Load and Start Southern Coronal Hole Study for 20 - 21 August 2002 Load Synoptic for 21 August 2002 Load Southern Coronal Hole Study for 21 - 22 August 2002 Load Southern Coronal Hole Study for 22 August 2002 Load Mini Synoptic for 22 August 2002 SOHO Activity: Received via email from SOC on Mon, -------------- 19 Aug 2002 18:50:13 UT Tuesday 20 August ----------------- D66 from 10:25-18:50 UT D16 from 18:30-02:20 UT SOC at EOF by 10:30 UT SSR will be dumped NRT enabled for LASCO to close doors Offpoint activities begin at ~11 UT (~7am local time) Transition to VC2 for the duration of the offpoint (~11:16 UT) If VC2 becomes unavailable, go to VC3 VC3 is required for the handover NRT enabled for MDI for ~30 minutes FOT will begin the Profile in NM/RMW script Script Step 1 - Initial Verifications (~1 minute) Script Step 2 - Instrument Status Verification (~10 minutes) FOT will Disable the offpoint flag to MDI, LASCO, UVCS Disable ESR flag to LASCO Script Step 3 - Maneuver Preparation (~10 minutes) RSL will be disabled Enable NRT for MDI to open loop and command Wait until MDI has completed 1 hour of observations and until MDI and EIT have completed their Step 0 observations Script Step 4 - Attitude Profile (~5 hours) - will begin after 8am local Begin offpoint steps 1-13 FOT will enable NRT at each dwell point SOC will connect EIT for commanding EIT will tell SOC when they are done with the NRT and the 304 image is acceptable (~4 minutes into the dwell) SOC will tell FOT that they can take the NRT link and prepare for the next profile MDI will tell SOC when they are done with their observations SOC will tell FOT that they can execute next profile NOTE: EIT will first take a 304 image (this will take about 4 minutes) and if the telemetry is good they will tell the SOC that they are done with NRT and observations. If the telemetry is bad, they will need to redo the image, which means they will need NRT for an additional 5 minutes to retake and confirm another 304 image. The following coordinates are given with respect to spacecraft position. These numbers are deltas from the current position.

Step 18 can be waived in case of serious delays threatening to overrun the total time constraints. To further reduce time step 15 can be waived, then step 14. step # yaw pitch dwell 14 -700" 0" 25 min 15 720" 0" 20 min 16 -700" 0" 20 min *** SKIP *** 17 0" 0" 0 min 18 0" -600" 25 min Begin offpoint step 19 step # yaw pitch dwell 19 0" 30" 10 min Enable ESR flag to LASCO/EIT Enable NRT for LASCO to open the C2 door MDI and EIT and LASCO finish commanding and observing Begin offpoint step 20 step # yaw pitch dwell 20 0" 0" 5 min MDI and EIT and LASCO finish commanding and observing FOT notifies SOC that offpoint is complete Script Step 5 - Post-Maneuver Configuration (~30 minutes or more) Enable the offpoint flag to MDI, LASCO, UVCS Enable RSL FOT script complete Handover at ~18:30 UT Enable NRT with VC2 MDI will close the ISS loop MDI needs 1 hour of NRT with VC2 LASCO needs 2 hours of NRT for EIT calibrations NRT for UVCS recovery Received via email from SOC on Fri, 23 Aug 2002 19:32:56 UT As-Run Offpoint Schedule for Tuesday 20 August 2002 --------------------------------------------------- Monday 19 August: 18:08 UVCS safing begun 18:21 UVCS safing complete 21:20 EIT pre-offpoint calibrations begun Tuesday 20 August: 01:33 EIT pre-offpoint calibrations complete 10:46 LASCO close doors procedure begun 11:18 MDI pre-offpoint observations begun 11:59 Offpoint flag disabled 12:04 ESR flag disabled to LASCO only 12:05 RSL disabled 12:28 MDI opened ISS loop 12:35 Step 0 observations complete for MDI and EIT 12:40 Profile begun to go to (0,-100) 12:46 Profile complete and Step 1 observations begun 12:55 Profile begun to go to (0,-225) 13:02 Profile complete and Step 2 observations begun 13:10 Profile begun to go to (300,-225) 13:18 Profile complete and Step 3 observations begun 13:27 Profile begun to go to (-225,-225) 13:34 Profile complete and Step 4 observations begun 13:43 Profile begun to go to (-225,0) 13:50 Profile complete and Step 5 observations begun 13:59 Profile begun to go to (-100,0) 14:06 Profile complete and Step 6 observations begun 14:14 Profile begun to go to (68,0) 14:22 Profile complete and Step 7 observations begun 14:30 Profile begun to go to (383,0) 14:38 Profile complete and Step 8 observations begun 14:47 Profile begun to go to (383,383) 14:54 Profile complete and Step 9 observations begun 15:08 Profile begun to go to (-300,383) 15:15 Profile complete and Step 10 observations begun 15:24 Profile begun to go to (0,383) 15:31 Profile complete and Step 11 observations begun 15:43 Profile begun to go to (0,68) 15:51 Profile complete and Step 12 observations begun 15:59 Profile begun to go to (0,0) 16:06 Profile complete and Step 13 observations begun 16:16 Profile begun to go to (-700,0) 16:23 Profile complete and Step 14 observations begun 16:48 Profile begun to go to (720,0) 16:56 Profile complete and Step 15 observations begun Step 16 was skipped 17:20 Profile begun to go to (0,0) 17:29 Profile complete and profile begun to go to (0,-600) 17:36 Profile complete and Step 18 observations begun 18:12 Profile begun to go to (0,30) 18:20 Profile complete and Step 19 observations begun 18:21 ESR flag enabled to LASCO 18:31 LASCO C2 door opened 18:50 Profile begun to go to (0,0) 18:56 Profile complete 18:57 Step 20 observations begun 19:03 MDI closed ISS loop 19:04 Step 20 observations complete 19:09 Offpoint flag enabled to LASCO, MDI, UVCS Roll Anomaly Flag triggered as expected 19:20 RSL enabled 20:03 MDI post-offpoint observations begun 20:03 LASCO C3 door opened and EIT post-offpoint calibrations 20:10 UVCS recovery begun 20:18 UVCS recovery complete 20:37 MDI post-offpoint observations complete 22:05 EIT post-offpoint calibrations complete EOF Staff: M.

Goal is to measure the properties of a high-latitude coronal hole. In particular we are interested in the coronal conditions (intensities and line widths for HI Ly-alpha and OVI 1032/1037) as a function of height and latitude. We will compare these properties with the ones found in polar coronal holes. Roll positions are VL-corrected for PA=216 degrees.
