10minNews & AnnouncementsAll


  • Welcome to Aarynn Carter, a new member of the JWST NIRISS and TSO CT teams.
  • Sarah Kendrew mentions plans to make the TA optional for MIRI LRS. In addition, the MIRI team has the MCOR noise suppression for subarrays finally pushed.
  • Everett Schlawin asks if the introduction of a slit to LRS implies no shadow region effect. Sarah Kendrew confirms that the shadow effect will be gone when using MIRI with a the slit. Right now, the slit only allows FULL array readout, so the dynamic range is limited compared to the case where the a subarray is used in slitless mode.


10minPast and future TSO observations

Nikolay Nikolov


  • Nikolay Nikolov presents planned and past TSOs. Most used mode is NIRSpec BOTS, followed by MIRI Imaging and LERS, NIRISS SOSS and NIRCam Grism Time Series. Most observed objects are transiting exoplanets (transits and eclipses), monitoring of variability in Brown Dwarfs, ISM and variability in a black hole.
  • Michael Regan asks why ISM is observed in the TSO mode, as one can obtain high SNR in multi-dithered exposure, and the analysis by the pipeline is much easier that way.
  • Nestor Espinoza mentions that we will check with the PI and encourage them to use multi-dithered data.
