IR News (1Dec93)
(from CTIO, NOAO Newsletter No. 36, 1 December 1993)

                             CTIO Projects

Both the IRS Upgrade and the HgCdTe Imager projects are on schedule for
commissioning toward the end of next semester.  We therefore expect to
be able to offer them second semester 1994 - but be sure to check the
March Newsletter for an update before writing your proposals!

                              OSIRIS News

Observations with OSIRIS have gone well, with the biggest difficulty by
far being acquisition of guide stars for spectroscopic work. The
restricted guider field at f/30 means that at high latitudes or in dark
clouds, there is often no star available from the HST Guide Star
Catalog. If you have OSIRIS time on the 4-m, unless you are confident
that such stars will be available, we urge you to come prepared. Ideally
you should have a list of guide stars, and if not, the minimum is a good
finding chart of known scale.

We will send out more information to observers granted time next
semester; anyone currently assigned time should contact one of the
undersigned with questions.
