-Nancy, Sarah, Ben and Eric Bellm recently had a discussion with Shri Kulkarni about the possibility of putting v2 of a robotic spectrograph for fast transient classification on the 3.5m. The first version of this instrument, developed for ZTF as an R ~ 100 spectrograph for supernova classification spectroscopy, has been on the 60" telescope at Palomar and it is the leading classifier of transients. In addition to being an IFU spectrograph there is an EMCCD that can used in imaging mode or photon-counting mode (but it has a small FOV and an occultation in the center of the frame due to a pickoff mirror). It has been used for stellar science, AGN, and other science, but transient classification is really its main goal. We need to understand from the 3.5m user community whether there is an appetite for devoting some telescope time to this kind of science. This topic raised some great questions and comments:+Nancy, Sarah, Ben and Eric Bellm recently had a discussion with Shri Kulkarni about the possibility of putting a robotic spectrograph for fast transient classification on the 3.5m.

   * Bill: who would be doing the observing for this kind of project? Nancy/Eric: that's really up to us to decide, but we don't have an expectation that this would fall on the shoulders of the observing specialists.   * Bill: who would be doing the observing for this kind of project?

   * Adam: would users be able to propose to use the instrument for their own programs or would it be used only for transient observations? Nancy: We would want our users to be able to use it for other science.    * Adam: would users be able to propose to use the instrument for their own programs or would it be used only for transient observations?

   * Adam: what is its primary advantage over KOSMOS given the wavelength coverage? Nancy: it has lower spectral resolution (which some but not all users would want) and the data are reduced and posted very rapidly (~ 15 minutes from data acquisition to posting online).   * Adam: what is its primary advantage over KOSMOS given the wavelength coverage?

-**Nancy will draft a synopsis of this discussion and send it to the Users Committee reps. The reps will then send it to their users and solicit their feedback in time for the next meeting.** Meanwhile Nancy will continue to discuss the technical aspects of this with the observatory staff to determine whether this is a viable option.+**Nancy will draft a synopsis of this discussion and send it to the Users Committee reps.
