Shift L3108. Start at 024:13:00 GMT = 08:00am 24 Jan EST End 10:00am 24 Jan SOT Lead DAS (Times will be given in GMT on day 024.) PLAN ---- Continue running load JAN2108B. Measure ACIS cti before and after perigee passage. Then do obsid 8446, an ACIS-S observation of CYG X-2 to study the scattering halo due to dust along the line of sight. Then do obsid 9800, continuation of the ACIS-S observation of 4C 74.26, to study the offset between the terminal X-ray and radio hotspots.

EPH temp: 113.80 degF EPH 27V: 26.84 NOTES/ISSUES/PROBLEMS From the 9am status meeting: Three supports over the past day. DSS-66 was 27 minutes late with telemetry lock due to line of sight issues. All support requirements were met nonetheless. One stored command segment was uplinked; on-board commands are good until 027:03:50. JAN2808A loads were approved yesterday. Sun remains extremely quiet, with X-ray activity below A-level. Prior to tomorrow's 7am EST pass call-up there will be NetApp cluster testing. Contingent upon approval of P009 database at today's FD CCB, the install will take place following the end of pass at 9am EST tomorrow. This is expected to take of order 30 minutes.
