In 2018 Q2 (and likely in future semesters), Bellm and Graham have programs for low-resolution spectroscopic follow-up with the 3.5m telescope at Apache Point Observatory. Typically our allocation will be 4-6 classically scheduled second-half nights per quarter, plus two ToO programs: one for young supernovae and one for relativistic transients. Target requests welcome by email and/or the GROWTH Marshal.
Line: 6 to 6
At the Telescopio Nazionale Galileo (TNG) P.I. F .Taddia has a program for follow-up observation (optical spectra and imaging with DOLORES) of core-collapse supernovae. Te program is called "Observing supernovae from the Zwicky Transient Facility with the TNG". A total of 30 hrs distributed over 10 nights are available beween Octorber 2017 and April 2018. Here the schedule of the telescope until April 2018: http://www.tng.iac.es/observing/schedules/aot36/schedule.html. A new application for the same program between April 2018 and September 2019 will be submitted before November 17 2017. Contact person: Jesper Sollerman, jesper@astro.su.se.
At the Gemini-N telescope P.I. Avishay Gal-Yam has a program for ToO observations of young transients from ZTF. 10h of band A ToO time is available per year. The expected mode of use would be optical spectroscopy using GMOS. Contact person: avishay.gal-yam@weizmann.ac.il; steve.schulze@weizmann.ac.il
