              ------------- ACTIVITY LOG --------------
Observing Specialist: N.Ule
The GIFS LN2 tank was frozen over during the fills, had to refill later in
the night.  Some clouds and local rain in the area postponed the opening by
45 minutes but the weather cleared up after that.
Also, the chain that holds the LN2 tanks for TSPEC and Nic-Fps is broken
(the clasp is broken).
