Agenda Items:

News from the Pole:

South Pole crew busy setting up for air drop or  possibly a landing.


AASTO: TEG died, Shutdown, not sure why. Now back up and running, but
took a full day to get going again. Plume was knocked off. It accumulates
4 - 6" of ice per day - Charlie is knocking off everyday.

Medical: Current plan. Twin otter to arrive later this week, they
are rated to -100F. Will have two planes on continent. Betty Carlisle
will be left to stay. Ron doing fine - not enthused about leaving.

AST/RO beginning transition from CO 2-1 in SMC to 490 GHz CI in GC.

DASI - working well, big push on getting results out.

ACBAR - up and running, lots of test data, moon door down. No
drift scans (for CMB) yet, but they are in the works.

FUNDING - JC stressing need to address new proposals to
Peacock. CARA year 11 in "process" Will forward to
sub-contracts as soon as Chicago gets info.

SIP- Pernic: All projects need to send Pernic project description.

TONY - will send out web site address that CARA people can
review new site testing information.

Liquid Helium:

 status - 1 wessington at 2000 liter, evap 11-15 l/day
          3000 gal at 20 l/day; might last until Jan 1 if untapped?

** Charlie will send photo of 3000 gal level scale to help
   us understand status of 3000 gal supply **

what about next winter?
   if *ALL* full (3 wessingtons and 3000 gal storage dewar)
   then we will run out at end of season, this simple calculation
   does not include any contingencies -- we need to address this
   in the SIP. Use SIP to push for an updated plan? Cold fingers?...

***Charlie pointed out that new Cryo facility ought to be in Dark
   Sector.   ***

FTS is largest users - 1/3 of total
 *** What do we do about FTS? Is it worth 1/3 of helium supply ? ***
