Changes since the Cycle 22 Call for Proposals has been Frozen
April 03, 2014
ProPer Profile Link incorrect in Call for Proposals has been updated
The Weblink in the Cycle 22 Call for Proposals was incorrect for the ProPer Profile Address information. That link has now been updated
in section 8.12 and 8.13. For reference the correct link to use is: https://profile.stsci.edu.

APT 22.0.2 was released for minor update
Two changes with this minor release. One corrects the schedulability you see with the Visit Planner if you have Orientation constraints -
some observation may become more schedulable. The other is a fix that allows APT to run on Linux using the fvwm2 windowing system.

SNAPshot observations of moving targets within the orbit of Jupiter
Following discussions with the STUC, in Cycle 22 STScI will allow SNAPshot observations for solar system objects that lie within the orbit of Jupiter provided that the observations are undertaken under gyro control and meet the following criteria:
- The maximum apparent motion of the target as seen by HST, including both target motion and HST orbital parallax, must be less than 8.74 arcsecond/second;
- The target must lie more than 0.5 AU distance from Earth to limit orbital parallax corrections;
- Blind pointing errors under gyro control can reach 20 arcseconds, so the observations must be tolerant to that uncertainty;
- Integration times for single exposures should be limited to less than 15 minutes to minimise image smearing;
- Observations will not be allowed with COS, STIS/MAMA or the ACS/SBC.
Interested observers should contact the STScI HelpDesk for further information. Programs proposing to use gyro control for any observations must flag that requirement in the Special Requirements section of the proposal.
Standard SNAPshot observations of solar system objects within the orbit of Jupiter under guide star control will continue to be disallowed since identifying guide-stars for rapidly moving targets represents a prohibitive overhead for the HST scheduling team.
This update supersedes the information in Sect 3.3.3 of the Call for Proposals.

APT PDF Format Change
STScI has updated the format in which PI and Co-I names appear in proposal PDF files
generated by the APT software. The PI name no longer appears on the front page of
the proposal. All author names (PI and Co-Is) now appear on the second page with
initials instead of first names (e.g. E. Hubble not Edwin Hubble).
These changes have been made in an effort to reduce unconscious bias in the review process, by helping reviewers focus on the science being proposed rather than who is leading the proposal.

Joint XMM-HST Programs from XMM OTAC for Duplication Checking
For XMM-Newton's Cycle 13 and HST's Cycle 22, the XMM-Newton Observing Time Allocation Committee (OTAC) met in the fall of 2013 and reviewed their proposals. The six joint XMM-Newton proposals on listed on the results page have been approved for execution in HST Cycle 22. These observations will be processed during the normal HST cycle ingest after the HST Telescope Allocation Committee (TAC) meets in June of 2014 with those results released to the community by the end of June.
Since these programs haven't been loaded into our Duplication checking system you will need to review the results page to check for duplications against any proposed HST Cycle 22 Phase I Observations that you might be considering.
Up to 10% of the available HST observing time may be reserved for Director's Discretionary (DD) allocation.
