Night Summary
=============
no observations

Conditions
----------
gen:		cloudy
seeing:		-
wind:		0-10m/s
humid:		50-70%
temperature:	14-11C
loss:		all night


Technical Problems
------------------
problem:	see below
loss:		all night

Other Problems
--------------
After cryostat re-fill ice built up on the cryostat due to the high
humidity, probably because one or more o-rings lost their elasticity
and therefore their sealing property.  The pressure rose to 10E-1.  No
leak could however be found while on the telescope.  The cryostat was
warmed up and dismounted to be investigated in the detector lab clean
room.  Ice had formed inside the cryostat.  It is being baked (head
and inner tank).  Assistance from ODT/La Silla and ODT/Garching was
requested and N. Haddad and O. Iwert will come up to Paranal on Friday
and Saturday, resp.  Further actions and schedule TBD.  Detector not
expected to be operational before Sunday night.

General Comments
