Looks like it has all the same properties. Forgot to run target confirmation (although had confirmed by other means) 876158933 ----- Attempting Submission 1 (Mon Feb 02 20:34:07 GMT 2015) ----- Dust to Dust: Monitoring the Evolution of the New Class of Self-Obscured Transient The goal of this proposal is to understand a new class of explosive transients associated with the most massive AGB stars. Today these sources are true creatures of the mid-IR, being optically invisible and very faint in the near-IR. By coarsely monitoring them with Spitzer and HST we can examine the evolution of the luminosity, dust optical depth and dust radius/temperature at a key time when their observed fluxes are approaching those of the two known progenitors. At its very simplest, if they do not stop fading in the mid-IR or start to brighten in the near-IR, then they are almost certainly examples of the theoretically expected but observationally missing electron capture supernovae (ecSNe). The exciting result from Cycle 10 is that the sources continued to fade and two are becoming substantially fainter than their progenitors. If this continues in Cycle 11, the ecSNe interpretation becomes increasingly probable. Each observation is done as a 3 point line dither in F160W and F110W combined with one extra F110W exposure -- the latter is adjusted to come as close as possible to using the available time Each of the images is done as a STEP100 sequence Two of the targets, SN2002bu and SN2008S, are not placed at field center, but offset. In particular, this places another old SN in the field of view of the SN2008S observations. These pointings have all been used successfully in previous WFC3/IR observations of the targets.
