SOHO Daily Meeting Minutes for Thursday 22 May 2003


ANNOUNCEMENTS
-------------
* HGA Anomaly/possible maneuver update: 

  One piece of information omitted in the minutes yesterday was that 
  rolls in conjunction with an offpoint would most likely be limited 
  to about 20 degrees both ways.

  The antenna movements will be stopped at the turning point in the
  SOHO orbit on/about May 25 "to preserve the evidence" - by allowing
  the current HGA table to expire.

* Current RHESSI default target is AR10362. When selecting this 
  target to maximize coordination w/others, use campaign number 6850.

* SPWG on Friday in the EOF after the Daily & Weekly meetings

* GSFC phone voice mail will be taken down from 9pm on Friday night
  until 7am on Saturday morning.

* Commanding times for next week:

  Monday -    D66 until 14 UT then D27.
  Tuesday -   Commanding is good all day.
  Wednesday - Gap from 14-16:30 UT.
  Thursday -  Gap from 14:30-15 UT.
  Friday -    Gap from 16:30-17:30 UT.
  Saturday -  Commanding is good all day.
  Sunday -    Commanding is good all day.

MEDOC daily meeting  Thursday 22 May
( planning for the 23 May)

Recent observations:
Data from JOP 167 appears good; many SUMER lines and CDS data in coronal
hole

SUMER data for Ulysses quadrature  shows good density lines of Si VIII
and Temperature ratios of Mg IX

Planning for 23 May:

SUMER :  00:40 - 06:00 JOP 167     Pointing -1052, - 0650
         06:00 - 17:00 Ulysses Quadrature Pointing -1052, 275.
         after 18:30 - Change slit position to x=0

CDS :    04:20- 07:45  JOP 157  Point : 291,-166 and 307,-166
                     (with Meudon observatory)
         08:00 - 16:00  Ulysses Quad.  Point -972,244
         16:25 - 18:30  JOP 167 Point : 392,179
         20:20 - 01:00  JOP 163 Point : 82, 0.

UVCS     Supports Ulysses quadrature
