Observations from the 0.4m Whately Observatory in Western Massachusetts with the NICMASS Infrared camera have detected atmospheric features induced by impact "A". Observing in a 2.23-2.29um filter (deep in the methane band) at 00:20 UT we see a bright spot at the impact latitude about to disappear over the West limb. The spot is about 50 times fainter than Io (which just emerged from behind the planet). The feature was still visible at 01:34UT. Observers were Mike Skrutskie and Sven Aas from the University of Massachusetts.
