NOTES/ISSUES/PROBLEMS
From the 9am status meeting:
All data current. Uploaded one command segment, on-board loads good until
061:18:15.

Ran CAP 563a, the CPE warm start count still reads 1 as expected.

The FEB2601c load will be shortened by a day, and MAR0501 will start a
day early, in order to accomodate the next TOO of the gamma ray
burster (same burster as last week) and to make up the HDF-N survey
time. Products went out yesterday for a load review at 2pm today.

GOT working with SGI changing power supplies on the servers.


Quick look data:
No new data today.
