SOHO Daily Meeting Minutes for Wednesday 25 June 2003

ANNOUNCEMENTS

* We expect to lose the high gain antenna link on Wednesday or
Thursday of this week for ~20 days. Starting Wednesday, we are
scheduling daily passes on 34 meter stations for monitoring and
commanding of the spacecraft. The 34 meter schedule for this week
is included below. Since the times are very limited, we’d like to
request that ALL TEAMS BE AVAILABLE (at EOF or by phone) during the
passes, in case your instrument comes up in an unexpected state.
When downlink only 34 meter stations are scheduled, a 26 meter
station will be used for uplink (i.e. all 34 meter passes will
have commanding capability).

Week 26 34-Meter Passes

                   BOT   EOT
                 --------------
   Wed     DSS-65 15:05-18:25 UT D/L only and DSS-16 26-meter overlap        
   Thurs   DSS-54 15:30-17:45 UT
   Fri     DSS-54 13:00-17:45 UT
   Sat     DSS-24 17:35-20:35 UT
   Sun     DSS-54 13:00-17:30 UT

* Current RHESSI default target is AR10386. When selecting this
target to maximize coordination w/others, use campaign number 6850.

* GITT scans for the EOF and EAF are scheduled for Thursday 26 June
at 9:30am.

* SPWG on Friday in the EOF at 10am.

* CNE network outage from 6-8pm on Wednesday 2 July. Internet access,
e-mail services and building to building traffic will be intermittent.
