NOTES/ISSUES/PROBLEMS
From the 9am status meeting:
Three supports over the past day, including one in progress. No
issues. 
JAN3006 products out no earlier than the end of today. No load review
today. 
EPHIN 27v still low, and temperature high. May recover during current
perigee passage.
Peter Ford has diagnosed an ACIS cti measurement bias map corruption,
obsid 59165, as due to telemetry corruption. Requires more than a single 
bit error.
