MDM Trouble Report for 2005 Jun 27

Telescope: 2.4m
Observer(s): J. Thorstensen, H. Sheets\ (Dartmouth)
Instrument: Modspec + echelle CCD

Problem(s) Encountered:
Two problems:

(a) In the afternoon we noticed that the shutter
in the modspec was intermittently failing to open all the way.
Fortunately Bob was still here and he was able to fix it before
leaving (a little late). Thanks again, Bob!

(b) As we were filling the dewar in the AM, the hose-mount
fixture blew clean off the OSU 50-liter dewar.  Made quite a
racket, we got to it right away and didn't waste much LN2.  
The other dewar had its pressure valve open so we had to charge
it with the hose.
