Doing several pool targets: Obsid 5712 and 5716, an ACIS-S survey of jets in FIRST (Faint Images of the Radio Sky at Twenty-centimeters) sources; obsid 5704, an ACIS-S survey of bright broad absorption line (BAL) quasars; 5803, an ACIS-I imaging project on massive clusters of galaxies observed in the Deep Lens Survey (DLS); 5393, 5394 and 5388, part of an ACIS-S survey of B/A-type stars with strong magnetic fields; 5633, part of an ACIS-S study of intermediate-redshift narrow-line Seyfert 1 galaxies.

EPH temp 98.62 degF NOTES/ISSUES/PROBLEMS From the 9am status meeting: Four supports over the past day. A DSS-16 was changed to DSS-24 because INTEGRAL needed extra support. Data dumps are all current. One load segment was uplinked -- On-board loads good until 084:21:48. MAR2805 products are still in work. There is an issue with a couple of observations which were being planned but were not in the OR list -- needs to be resolved. No load review today. UPS battery replacement is scheduled to begin at 1pm EST tomorrow afternoon. All 40 batteries are being replaced. It is guessed that the activity will be finished by 4pm. We will confirm from the vendor the expected work duration, and also the fact that they will not leave the UPS in an inoperable state at the end of their workday. To mitigate against the database server corruption which would occur if house power failed with no backup, we will bring the databases down while the replacement is in progress. The 5:30pm EST pass tomorrow is not deemed essential. Manual operation of the generator is considered a possibility in case the house power does fail while UPS is not operable.
