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
