• Nikolay Nikolov exits the TSO CT as a deputy lead and member. This is his last meeting.
• Welcome to Ian Wong - a new MIRI TSO member. 
• Knicole Colon is the new JWST Operations Project Scientist in NASA Goddard, and moves from TESS to JWST.

Nikolay Nikolov

Nikolay Nikolov reports TSO observations past two weeks and upcoming two weeks. Mentions repeats due to TA failure.

Sarah Kendrew points out a skipped observation that was not reported, because it was recent an a TTRB has been just submitted. This one was skipped because the observatory was behind schedule.

•  Nestor Espinoza will contact the schedulers to discuss the percentage of TSOs with this issue.

Everett Schlawin 

• Everett Schlawin introduces the DHS capability at the NIRCam SW. With the DHS enabled observers will be able to obtain spectra on both SW and LW simultaneously. 

  He reports the recent observing status for enabling the DHS mode with data now available for the following calibration aspects: 

  • flux calibration
  • wavelength calibration
  • new field points to put the spectra on the two detector rows on the SW for faster read

  A new program is developed to check a few filters that were not examined yet, and test the new field points. He also elaborates that the SW and LW detector modes are locked (by design) to have the same timing. This and the goal to observe bright targets have been the driver to move to smaller 32 pixel subarrays.

  Questions for the TSO CT:

• What do people in this group think are the risks by going that narrow?
