Late-Time UV Spectroscopic Signatures from Circumstellar Interaction in Type IIn Supernovae Type IIn supernovae (SNe IIn) are defined by their relatively narrow spectral features associated with a dense circumstellar medium (CSM) formed by the progenitor star. The nature of the progenitors and mass loss remains relatively unknown. Shock interaction with the dense CSM offers an important probe of the CSM characteristics, progenitor mass-loss history, and ultimately the progenitor itself. While most supernovae tend to be faint in the UV at late times (>200 days), shock interaction and dust formation in the dense CSM often result in significant emission ranging from X-ray to radio for many years post-explosion. Here we propose HST/STIS observations of 4 relatively bright, nearby SNe IIn that reflect the diversity and significance of the subclass. The SNe 2005ip, 2006gy, 20009ip, and 2010jl are some of the most well-studied SNe IIn, and our team has already compiled a comprehensive set of multi-wavelength data that has resulted in numerous publications, but the UV remains largely unexplored. Recent observations indicate these SNe are still detectable. UV observations will (1) constrain the CSM characteristics, including geometry and composition, (2) confirm shock interaction as the heating source for late-time emission from warm dust, and (3) explore the possible presence of a scattered-light echo in SN 2006gy. Coinciding with Cycle 21's UV Initiative, this program offers new insights regarding both the progenitor and explosion characteristics of the SN IIn subclass. We propose to obtain a single STIS-MAMA spectrum of SNe 2005ip, 2009ip, and 2010jl in both the G140 and G230L bandpasses. The goal is to detect UV signatures of CSM interaction to (1) constrain the CSM characteristics, including the geometry and composition, and (2) confirm emission from CSM interaction as the heating source in the warm-dust model presented by Fox et al. (2011). We also plan a single STIS-CCD optical spectrum of SN 2006gy to (3) confirm the presence of a scattered-light echo and probe the original peak SN spectrum. A color from STIS-MAMA imaging will provide a basis for estimating exposure times for a UV spectrum of SN 2006gy in Cycle 22. We choose STIS over COS because, while COS is optimized for isolated faint point-sources, STIS offers spatially resolved spectra that exploit the intrinsically high resolution of HST over a large spectral range (accommodating both the C III] 1909 and Mg II 2800 lines). The long slit length will allow us to subtract contamination from zodiacal light, earthshine, the host galaxy, and H II regions.

CASM was run in Phase II mode. Requires an offset >30 arcseconds aways. We have precisely located the position of SN 2010jl in the latest WFC3 image that our team triggered in November. The offset ACQ star, however, is only located in a pre-SN image of the galaxy taken with WFPC2 F300W. We've matched the astrometry in these two images and identified the precise SN position in the WFPC2 image to calculate the offset from the ACQ star. Unlike the previous set of observations, we now know the precise offset, so we are not limited to a single rotation angle. This means we are also not limited to only a single guide star. Therefore, we don't need to accomodate for any drift. We have therefore implemented 2 major changes from our previous Phase 2. 1) 0.5" slit -> 0.2" slit. 2) No limit on the rotation angle.
