REAL TIME OBSERVATIONS GMT OBSID ---------------------- ---- ----- 3 fids, 5 stars 1450 2311 Eric Martin reports that one of the fids has a bad pixel flag. The image looks quite normal. The only impact is that the OBC doesn't think it's a fid, but that should not affect anything else. Notes from 9 am meeting ------------------------ OPS: Passes 2 over the last day(s) Data loss none Load is good -> 027:16:31 CAPs 563A CPE warm start = 1 next passes 1445, 0000, 1000(LETG) MP: The JAN2901 load was revised, new products out this PM. The Feb05 load has a time slot for a TOO that will be decided upon in the next day or so. The NEAR spacecraft will impact on Eros on Feb 12. This affects our antenna plan, but no problem. S/C: We will execute CAP 690B to retract LETG this Thursday, day 025 at 10:30-11:30 GMT (5:30 AM EST). GOT: For those who use the EGSE, remember to check it out after the new backup server is installed today. SOT: Radiation continues to decrease from yesterday's high. ASCDS: One QL. No QL processing until the weekend(see email at end of this report).

Nichols" To: ascds_dutysci@head-cfa.harvard.edu, operators@head-cfa.harvard.edu, syshelp@head-cfa.harvard.edu, sot@head-cfa.harvard.edu Hi The following is our plan for the downtime planned to begin late tomorrow morning and end sometime of Thursday (TBR). ======================= Production AP processing is expected to go idle between 2am and 6am tomorrow. Repro AP is expected to go idle between 4am and 8am. Realtime data will be received as usual on psicorp; however, the multimon and acorn code will be on a local psicorp disk. The code has already been moved, but we will not switch to the local software code until Lisa indicates it is time to remove our dependency from external disks tomorrow morning. When given the signal, we will bring down acorn and multimon, then bring them back up with the local version of the software, from a local disk area that will be used to collect the raw data. The GOT will NOT be able to transfer data to us during the downtime. We will turn off our automatic retrieval and processing jobs. ***NOTE:**** If there is an urgent need for quicklook data or processing of L0 data for engineering data, etc., we will be able to retrieve the dump data from the GOT on CD and bring it to Garden St. to process. We plan to be able to support spacecraft anomaly and TOO needs by doing this. Please page me (1-888-849-7469) if the need arises. ************* Quicklook data will not be available Wed., Thurs, or Friday morning. The next quicklook image is one of the full orbit observations that take a very long time to process. The quicklooks will start to be available approximately 12 hours after the computer system comes back up, and the images will be placed on the web pages over the weekend as fast as we can make them. We apologize for any inconvenience, but we are gaining new disk space that will speed up the processing, so it's worth it.
