The image above shows ASASSN-13dl in all 6 UVOT filters, from reddest (V) to bluest (UVW2), as observed by Swift on Oct. 11. The position of the supernova is indicated in each image by a circle with a 4" radius. We measured the magnitude of the source in each of these bands and found that it was not detected in the farthest-UV (UVM2 and UVW2) filters, but that its other colors (UVW1-B, U-B, and B-V) are all fairly consistent with a Type Ia supernova at peak magnitude. However, it does appear to be fainter in the U-band than expected, and its host galaxy is uncatalogued, so we will be continuing to monitor ASASSN-13dl for more interesting behavior going forward.
