Following the discovery and classification of ASASSN-14lp (ATEL #6795 and ATEL #6801) as a young, nearby (D ~ 18 Mpc) Type Ia supernova, we triggered STIS UV observations with the Hubble Space Telescope under the Cycle 22 program "Understanding the Progenitor Systems, Explosion Mechanisms, and Cosmological Utility of Type Ia Supernovae" (GO-13646; PI Foley). The first epoch of HST UV spectroscopy is currently scheduled to occur on 15 Dec 2014 at about 01:55 UT. There will be a total of 10 epochs of HST spectroscopy over the span of a month, with an initial cadence of roughly 2 days. We encourage additional and simultaneous follow-up observations at all wavelengths.
We thank the STScI staff, especially A. Armstrong, G. Chapman, P. Sonnentrucker, and N. Walborn, for implementing this trigger.
