HST programs over the next several weeks.

Revisions to Recommendations for COS Target Acquisitions

For phase 2 of Cycle 18 there are some important changes to the
recommended COS target acquisition procedures. The details of these changes
and current recommendations are discussed in COS ISR 2010-14. Most notable is the relaxation
of the requirement that essentially all COS observing programs start with an
ACQ/SEARCH exposure sequence. A detailed discussion of when
a simplified acquisition strategy can be used is presented in this STAN
article.

APT Changes of Special Interest to COS and STIS Observers.

APT version 18.2 has been released with the following changes: GALAX data was added
to the Bright Object Tool for field checks, mas/yr and "/yr were included as proper 
motion units, and the display of the relationship between the STIS long-slits and 
the MAMA detectors was improved. This version must be used for all Cycle 18 Phase 2 
proposal submissions.
