Here some context about the observation plan these images were taken for:
https://www.stsci.edu/jwst/science-exec ... ml?id=1349
Principal Investigator: Ryan Lau
PI Institution: ISAS, Japan Aerospace Exploration Agency
Title: Establishing Extreme Dynamic Range with JWST: Decoding Smoke Signals in the Glare of a Wolf-Rayet Binary
JWST Proposal 1349 (Created: Monday, July 25, 2022 at 12:00:13 PM Eastern Standard Time)
While the web page shows ISAS as PI institute, the PDF lists Caltech with a noirlab.edu email address for Ryan Lau, so he either moved from ISAS to Caltech or vice versa.
Surprising to see that the observation plan was filed only 4 days ago. Though there might have been a placeholder schedule entry before, I don't know.
