 Observing Specialist, 1st & 2nd Shift: Noel Camron Hastings
    Clouds clouds clouds snow clouds. Cirrus in early AM, but too late to
get open in time for science. When I filled the instruments this AM the
echelle was again at 0 psi. The popoff valve was not frozen open as far
as I could tell. I used the large dewar to re-pressurize. This needs to
be checked regularly since it seems that it happens regularly now.
