SOHO Daily Meeting Minutes for Tuesday 27 May 2003 ANNOUNCEMENTS ------------- * HGA Anomaly maneuver update: A decision has not yet been made on whether or not there will be a maneuver, nor on the precise nature of such a maneuver (e.g. whether there will be a limited roll from an offpointed position, or an HGA Y axis movement). However, the likely date for a maneuver would be Wednesday 4 June, with the SORR taking place on Friday 30 May. Note that there is a Mars Express launch on Monday; if it slips, it will make a maneuver on 4 June impossible. * Current RHESSI default target is AR10365. When selecting this target to maximize coordination w/others, use campaign number 6850. * Voice boxes will be down on Tuesday from 9am-11am. * Wednesday, 28 May between 2 and 4:30 PM EDT (18-20:30 UT) there will be some short outages on the TRACE network during an upgrade. * Submode change on Friday at 15 UT FOT REPORT ---------- Spacecraft Status: Nominal: HGA monitoring disabled; No New HGA uploads per OCD direction.
