The remaining warning is a benign reminder that the current list of investigators differs from the list originally submitted. The resubmission on 6/16/21 redistributed the 4 orbits allocated to Target 1 = AV 196 to 2 visits to facilitate scheduling. The replanned version has Visit 1C (1 orbit) for G130M/1291 and G160M/1611 Visit 1D (3 orbits) for G130M/1096 The resubmission on 9/24/21 is in response HOPR 92100, which reported failure to reacquire guide stars at the beginning of orbits 2 and 3 of visit 1D. This replanned version has Visit AD (2 orbits) for G130M/1096 which includes the exposures that were skipped in Visit 1D, as authorized by the TTRB. The resubmission on 3/2/22 is in response to HOPR 92173, which reported loss of data due to the failure to reacquire guide stars at the beginning of orbit 2 of visit AD. This replanned version has Visit FD (1 orbit) for COS G130M/1096, which repeats the exposures that were lost in Visit AD, as authorized by the TTRB. -1065827920 ----- Attempting Submission 1 (Mon Jun 07 20:39:28 GMT 2021) ----- HST Phase II Proposal 16371 successfully submitted.

Receipt: # 16371-3 ----- Attempting Submission 4 (Wed Mar 02 22:43:01 GMT 2022) ----- The Space Telescope Science Institute (STScI) Director has decided to devote up to 1000 orbits of Director's Discretionary time in observing Cycles 27-29 to a new Hubble Ultraviolet Legacy program focused on star formation and associated stellar physics. This new program, ULLYSES (UV Legacy Library of Young Stars as Essential Standards), will provide a UV spectroscopic reference sample of young (< 10 Myr) high- and low-mass stars. It will target over ~150 OB stars in the Magellanic Clouds and lower metallicity galaxies in the Local Group, and ~40 T Tauri stars and brown dwarfs in the Milky Way. In addition, ULLYSES will monitor 4 typical T Tauri stars over different rotational phases through at least three rotation periods, and over timescales of months to years. The resulting library will provide template spectra of massive stars at metallicities substantially below the well studied, while the low mass sample will cover a wide range of ages, accretion rates, and masses, including objects down to well below 0.5 M_sun. The legacy of this large UV dataset on the first 10 Myr of stellar evolution will be enhanced by complementary datasets obtained by the scientific community. In addition to the core goals of the program related to stellar astrophysics of low and high mass stars, this data will also enable exciting science in the fields of ISM, CGM, jets, and exoplanets. ULLYSES will be modeled after the Frontier Fields program: all data obtained will be non-proprietary. The implementation team at STScI is developing high-level science data products and a sophisticated database and website for disseminating data from the ULLYSES program and ancillary datasets for the ULLYSES target sample from space and ground-based facilities. This proposal includes a subset of the massive ULLYSES stars being observed in the Magellanic clouds. Depending on target brightness, the main FUV spectral range will generally use either the STIS E140M setting or the combination of the COS c1291 + c1611 settings. Sufficiently bright stars without good FUSE data in the archive will also be observed with the COS c1096 setting to provide coverage at shorter wavelengths. Where time permits, stars of type O9 or later will also be observed with STIS E230M/1978, while for supergiants of spectral type B5 or later E230M/2707 may also be included. Where possible, targets of a given spectral type were selected to span both a range in extinction and in rotation rates to support a variety of stellar and ISM studies. Signal-to-noise requirements used to determine the desired exposures times were defined as follows: COS/G130M/c1096: 20 / nine-pixel resel at 1080 A COS/G130M/c1291: 30 / six-pixel resel at 1150 A COS/G160M/c1611: 30 / six-pixel resel at 1590 A COS/G185M/c1953: 30 / three-pixel resel at 1860 A COS/G185M/c1986: 30 / three-pixel resel at 1980 A STIS/E140M/c1425: 20 / two-pixel resel at 1200 A STIS/E230M/c1978: 20 / two-pixel resel at 1800 A STIS/E230M/c2707: 20 / two-pixel resel at 2800 A The actual implemented exposure times may be adjusted to efficiently use HST orbits, but should always provide at least 80% of the desired time as defined by the above requirements. Additional details about the scientific motivation and technical implementation strategy of the ULLYSES observations can be found at http://www.stsci.edu/stsci-research/research-topics-and-programs/ullyses. The ULLYSES program is based on the recommendations of a working group led by Sally Oey; the full text of that group's report can be found at http://www.stsci.edu/files/live/sites/www/files/home/stsci-research/research-topics-and-programs/ullyses/_documents/HSTUV-report-ULLYSES.pdf. 0 false SUPPORTED EXT-STAR GIANT O OF NO tstatus; AV186; P/COS approved for submission; S/ins not started; P/AF 4/06/21; S/xx DD/MM/YY tcheck; APT/SIMBAD target names: ; AV186, 'AzV 186' ... other aliases include 2dFS 1230, Cl* NGC330 ELS 13, M2002 SMC 40341 tcheck; Target info verification status?; OK ...

Consequently, the total exposure time in the 4 FP-POS is somewhat unbalanced, with the first (archived from Visit 1D) exposure having longer duration: (FP-POS1, FP-POS2, FP-POS3, FP-POS4) = (1696 s, 1555 s, 1555 s, 1555s).

The total exposure time is 5920 seconds, which is 79% of the baseline exposure time to achieve S/N = 20 at the fiducial wavelength (1170 Angstroms).

The ETC run associated with the *planned* SNR is noted in the APT field. BOT: No stars are recognized in the GSC II catalog. 5 stars are marked as unknown, one of which is the science target.
