Because of the implied frequency of events similar to SN 2008S and NGC 300 and the interesting character of their progenitors, we searched for analogous sources in archival Spitzer imaging of nearby galaxies. Our goal was to identify the underlying subpopulation of massive stars from which these progenitors emerge, to characterize their properties and frequency, and to catalog them for future study. The Triangulum galaxy M33 is a perfect test case. It has an absolute B-band magnitude of MB~-19.2, a distance of ∼0.96Mpc, and it has extensive optical, Hα, MIR and FIR imaging. Description: We co-added six epochs of MIR imaging of M33 obtained between 2004 January 9 and 2006 February 4 with Spitzer/IRAC (3.6-8.0um; see McQuinn et al. 2007, Cat. J/ApJ/664/850, for details of the observing program). File Summary:
