Following the discovery and classification of SN 2014J (e.g., CBET 3792) as a young, nearby (D ~ 3.6 Mpc) Type Ia supernova, we triggered STIS UV observations with the Hubble Space Telescope under the Cycle 21 program "Understanding the Progenitor Systems, Explosion Mechanisms, and Cosmological Utility of Type Ia Supernovae" (GO-13286; PI Foley). The first epoch of HST UV spectroscopy is scheduled to occur on 26 Jan 2013 at about 11:45 UT. There will be a total of 10 epochs of HST spectroscopy over the span of a month. We encourage additional and simultaneous follow-up observations at all wavelengths.
