T85-T88
• Our sequence designer Alain Jouchoux writes,
‘T85 to T88 are beyond the radar for us right
now. We won't start designing for T85 until
January 2012 (we have no prime observation
in T85)’.
• Two EUVFUV primes in T86
• None in T87 or T88
Do we need the radial stare?
• Only a few pixels on the airglow
• Only spatial coverage in one dimension
• Provides good S/N, but an examination of the
close CIRS riders may be just as good
• Action item for someone (probably Mike
Stevens) to look at the CIRS riders

Upcoming PSG Action Items for the Discipline working groups:
1. Consolidated Senior Review Preparations: a. Firm up (as needed) the science objectives developed for
your discipline at the last PSG meeting. b. Given the limited page count, agree on just 2-3 topics for more
extended discussion in the Senior review proposal. c. Generate a detailed outline of your
section. 2. Gather key examples (especially graphics or ideas for new graphics) of "what's new" in the
remainder of the Solstice mission, with emphasis on high priority FY13, FY14 and FY15
science. 3. Decide on science talks for your discipline for Thursday’s plenary session. 4. Gather and
draft one or more nuggets for your discipline.
Heads up: there will be a TAMWG meeting on Wednesday of PSG week from 1-3
Note that the entire PSG will be webcast (like the TOST Preview Meeting) - more details to follow from the
project
Upcoming schedule:
February 17th: regular business
