SOHO Daily Meeting Minutes for Thursday 12 December 2002
ANNOUNCEMENTS
-------------
* Many schedule changes are taking place this week due to TDRS
spacecraft. The DSN and NRT schedule are changing faster than we
can keep up with them, so the web spacecraft schedule won't always
be updated. Call the SOCs for the latest information if you need it.
* Current RHESSI default target is AR 10220
* The Voice Distribution System (VDS) will undergo maintenance on Saturday
December 14 from 8am - 3pm. This downtime will be used to replace the
system's 48 VDC power supplies. During this downtime VDS users on
site at GSFC will not be able to signal Voice Control, use Dial
Intercom, and VDL Hotlines. All other VDS operations will not be
affected.
* SOHO potluck party is Tuesday, 17 December at 11:30 am, sign up in
EOF or FOT office soon.
* Commanding times for next week:
Monday - D27 until 18:30 UT then possibly D46.
Tuesday - Gap from 14:30-18:30 UT then D46.
Wednesday - D16 all day.
Thursday - D27 all day.
Friday - Demo test in the morning, D46 starts at 18:30 UT.
Saturday - Gap from 17-18:30 UT.
Sunday - Gap from 13-19 UT.
