Not needed because target is within a bright galaxy field.. The Nature of SPIRITS Mid-Infrared Extragalactic Transients Our team is conducting a large-scale time-domain search for mid-infrared (MIR) transients in 194 nearby galaxies, using the warm Spitzer telescope. This program, called SPIRITS (SPitzer InfraRed Intensive Transients Survey) is underway now, and will continue throughout all of HST Cycle 23. Among the astrophysical transients that we have found is a puzzling new class of luminous extragalactic MIR eruptions that lack conspicuous ground-based optical counterparts. They have MIR luminosities between those of novae and supernovae, and appear to be associated with spiral arms. Because of the lack of optical counterparts and of obvious progenitors, their exact nature is unclear. They have a wide range of eruption timescales, ranging from months to several years. To explore their nature, we propose to obtain deep images of eight such events during Cycle 23, using WFC3 UVIS and IR observations. These will be non-disruptive Targets of Opportunity, with the exposures obtained about 4 weeks after the Spitzer discoveries. We will select transients that are at sites previously imaged by HST, so that we can look for progenitor objects, characterize the stellar populations at the outburst sites, and attempt to detect faint optical or near-IR counterparts at HST depth and resolution. By observing 8 events, we will sample their diverse range of outburst timescales, luminosities, and other properties. This is a non-disruptive Target of Opportunity program, aimed at mid-IR transients discovered in our ongoing Spitzer program. When we find a new transient that satisfies our criteria, we will activate the TOO and obtain WFC3 images as soon as possible after the 3-week delay for non-disruptive TOOs. The WFC3 observations will be made in UVIS channel I band (F814W), and in IR channel J and H (F110W and F160W). We will use a 3-point dither in each filter.
