              ------------- ACTIVITY LOG --------------
Observing Specialist: P.Gaulme
Starting yesterday afternnon we saw that the echelle was consuming an exces=
sve amout on N2. Please refer to the problem report submitted (#1452).
Filling was normal at 00:00 and there was no frost on the valves. The press=
ue in the nurse tank was also normal and there was still a good amount of l=
iquid N2 (270 pds 6 hours after refill).
We did not have any technical problem, productive night.
