The object in question is SN 2009ip in NGC 7259. Although this object was discovered in 2009 and judged to be the eruption of a luminous blue variable star (LBV), it is now erupting again, which may well be the signature of its explosion as a supernova. We have been following this event at many wavelengths, including the UV with SWIFT. Although that gives us a baseline to estimate the UV properties of SN 2009ip, the SWIFT observations to date are quite limited. Ultraviolet observations with HST have proven exceptionally informative in some cases, such as SN 2010jl, and that is what we request here at the very end of Cycle 19. We have no further orbits left in our program GO12540, but this is a unique opportunity for HST. We request Director's Discretionary time for this set of observations, the first of which is a non-disruptive TOO. ------------------------------------------------------------------------------------ Observations Description ------------------------ TBD Real Time Justification ----------------------- 13179( 4) - 16-Oct-2012 02:34:05 - [ 2] Calibration Justification ------------------------- Additional Comments ------------------- ------------------------------------------------------------------------------------ 13179( 4) - 16-Oct-2012 02:34:05 - [ 3] TARGET LIST Fixed Targets ------------------------------------------------------------------------------------------------------------------------------------ Tar| Target | Target | Target |Coord | Radial | Flux data No | Name | Description | Position |Eqnx | Vel. | ------------------------------------------------------------------------------------------------------------------------------------ 2 SN2009IP EXT-STAR, SUPERNOVA RA=22H23M8.2600S +/- 0.1", J2000 V = 14.3 DEC=-28D56'52.40" +/- 0.1" Reference Frame: ICRS Comments: This object was generated by the targetselector and retrieved from the SIMBAD database. ------------------------------------------------------------------------------------------------------------------------------------ 13179( 4) - 16-Oct-2012 02:34:05 - [ 4] Visit: 01 Visit Requirements: BETWEEN 15-OCT-2012:00:00:00 AND 05-NOV-2012:00:00:00 On Hold Comments: Additional Comments: please try to schedule early in the SMS... if possible...

Currently, sn2009ip is about 2-3 times fainter in the UV then sn1998S. If STScI wants us to obtain the STIS spectrum first to make sure COS acq exposure time... thats fine with us. out latest SWIFT spectrum says acq exposure time of 120 seconds COS.ta.434043, so probably 240 is okay. we don't expect any emission lines brigher than geo coronal Lyman alpha.
