Here we propose a seven epoch STIS UV spectroscopic ``movie'' of a bright, ASAS-SN transient survey TDE spread over the first ~90 days after a rapid TOO trigger. The roughly 15 day cadence is comparable to the expected time scale for kinematic changes and the time scale of observed changes in the optical H and He lines. We will measure the evolution of UV absorption and emission lines from elements (e.g., C, N, Si) and ionization states/potentials not seen in optical spectra of TDEs, which should help to illuminate the dynamical evolution of these fascinating transients. In some cases, the debris from the stellar cores should have significantly enhanced [N/C] abundances due to the CNO cycle, so UV spectra can provide a means of differentiating debris from the core and the envelope of the disrupted star. The goal is to obtain a sequence of 7 STIS FUV-MAMA/G14L and NUV-MAMA/G230L UV spectra of a tidal disruption event, obtaining roughly one spectrum every 15 days for 90 days. Orbits are set for 1, 2, 2, 3, 4, 5 and 5 orbits for the first through seventh observations. First observation is a disruptive, rapid (but not ultra-rapid) 2-5 day TOO, followed by observations chained by 13-17 days. The second observation counts as a disruptive TOO, and the remainder are non-disruptive. We have set the acquisiton image for a point source with the standard F28X50LP filter and a 10 second exposure time -- this is appropriate for the early phases where any ASAS-SN bright ASAS-SN TDE should have V~17 mag -- should yield a SNR=79 according to the STIT acquistion ETC -- this should still be OK if the TDE is as bright as V~15, and hold for at least the first 1/2 of the visits.. The exposure times may need to be adjusted for the later 1/2 of the visits and may need a switch to a diffuse source as the TDE fades relative to its host. We have used an along slit dither to clean up hot pixels, with a step of 16 pixels to be larger than the recommended 0.35 arcsec -- we expect features fairly broad in velocity so we have not used dithers perpendicular to the slit. A minimum of two expousres are then taken at each dither position. The source should be well above sky, so the 0.2x50 slit should be fine for both the FUV and NUV observations. ----------- UPDATED SEPTEMBER 26 2016 The current target is fading fast, so we have decided to obtain one more epoch and then wait for a new trigger, hopefully one which is X-ray bright to go along with our approved 400 ksec Chandra TOO We modified the APT to do the 3rd epoch on the present target using 4 orbits simply by rearranging the visits CURRENT TARGET vist #1 (1 orbit, done), visit #2 (2 orbits, done), visit #5 (4 orbits) then we put in a new generic target which would use visit #3 (2 orbits), visit #4 (3 orbits), visit #6 (5 orbits) and visit #7 (5 orbits) - we understand that we would not be able to have a disruptive trigger with any new target and that there are risks associated with the observations to be coordianted with Juno - we have left the relative timing of these visits as in the original proposal, but can be flexible about the exact timing.
