Nikolay Nikolov mentions that SASP students will be arriving this weekend and start their projects next week. NN's student will be comparing public 1/f algorithms on NIRCam data.

Nikolay Nikolov summarized observations over the past two weeks; all executed successfully and the data is archived on the MAST. Next two weeks focus on exoplanets and ISM (for higher SNR) and will be using all JWST science instruments.

Nikolay Nikolov mentions that it is the time of the year to start planning FY2024 priorities for the TSO WG and invites the members of the TSO WG to propose ideas by reaching the TSO WG and communicate feedback. Part of the meeting was dedicated to brainstorm potential tasks with the results outlined below.

Brainstorm ideas during the meeting:

1. Reassessing the maximum exposure/visit duration for Time Series observations (Sarah Kendrew): 
   1. Sarah Kendrew points out the problem of having a limit of 24h on TSOs and suggests an investigation on the decision and its eventual reassessment for TSOs. Sarah Kendrew mentions that there are observations that request ~50hr long TSO and points out a work around solution, which covers the observation with two separate exposures. This could be done in one go, if the limitation is lifted. Sarah Kendrew and Brian Brooks point out that this issue has been captured by STScI: JPPS-1068. Michael Regan and Unknown User (birkmann) mention that the limit has been set to impose a stop of observations that have taken long time executing.
2. Optimization of individual pipeline calibration steps (Sarah Kendrew ):
   1. Sarah Kendrew suggests that there are several topics that can be researched in the next year, relevant on detector calibration in the context of MIRI including, ramp fitting, jump detection, etc., depending on ho much the TSO WG would like to go in optimizing the pipeline. Nikolay Nikolov mentions that this will be coordinated with the TSO WG Lead. Michael Regan mentions that the priority of the pipeline is to handle data that is on the archive in order to enable the data use by the science community.
3. Improvement of the reference files for all JWST instruments (Loic Albert):
   1. Loic Albert mentions that SOSS background and super bias are particularly important and need improvement
4. Investigate the role of super bias in the ramp fitting, instead of reference frame (Loic Albert )
5. Investigate transmission spectra across multiple JWST instruments (Nikolay Nikolov ):
   1. Requires coordination from all instruments to identify instrumental versus analysis origin (Loic Albert )
6. Identification of the cause for the visit-long slope (Nikolay Nikolov ):
   1. Not urgent, because a linear fit removes it, as demonstrated by community results
