1. Call for Cycle 32 Bridge Programs with WFC3/IR and ACS/WFC
HST is offering a supplemental Cycle 32 call for “Bridge programs” to transition science programs from WFC3/IR or ACS/WFC to other HST or JWST instruments. The call also represents a final opportunity for the community to propose for science programs that cannot be achieved without WFC3/IR or ACS/WFC. All proposals must fit into one of these categories. Please note that the regular Cycle 33 Call for Proposals will likely not include an option to propose for these modes. The Bridge proposal deadline is Nov 7, 2024 at 8pm.
The impetus for a call for Bridge programs is a projected gap in funding levels for HST beyond the end of Cycle 32 (Oct 2025). STScI and NASA are working to achieve cost savings by preserving the unique HST modes and removing modes redundant with capabilities present in other instruments or missions. This new operational change paradigm eliminates WFC3/IR and ACS/WFC from the long term slate of available HST modes. Calibration and instrument support for these modes will also be ramped down over this period after Cycle 32. Please note that WFC3/UVIS remains active; it is the WFC3/IR channel that will no longer be offered beyond Cycle 32.
Please also refer to the contemporaneous ACS STAN (October 2024), to obtain detailed information on the unique observing modes of ACS/WFC that will no longer be available after the Cycle 32 Bridge Programs.

2. AAS Meeting Workshop "Hands-on Hubble: How to Access, Align, Drizzle, and PSF Model HST Images"
M. Revalski
We hope you can join us for the first "Hands-on Hubble" workshop on Sunday, January 12th from 1-5pm at the 245th AAS meeting. In this interactive half-day workshop, Hubble Space Telescope (HST) experts will share the resources that are available to help you succeed in using HST imaging for your research. Specific topics will include how to download data, perform astrometric alignment, and create mosaics by drizzling images obtained with the Wide Field Camera 3 (WFC3) and other imagers on-board Hubble. We will also explore how to generate high-quality Point Spread Function (PSF) models for accurate astrometry and photometry. The workshop will focus on brief presentations of each topic followed by ample time for Q&A. In the second half of the session, experts will be on-hand to aid you with questions specific to the datasets you are analyzing. Users of all experience levels are welcome, with the material focused on first-time users and early career researchers who are looking to build their skills using Hubble observations. A basic familiarity with Python, Astropy, and Jupyter Notebooks will be helpful to fully benefit from the content of the workshop, but is not required. We encourage you to bring an HST dataset that you’re working on for your research. If you plan to attend, please be sure to select this workshop while registering for the 245th AAS meeting.
