IPAC, located on the Caltech campus, is not under direct threat from local fires at this time, though it is subject to the effects of strong winds and poor air quality. Many members of the IPAC community have been impacted by these events, and IPAC will follow Caltech guidance on closures and safe operations.

Abstract • We present optical and IR observations of the dwarf nova OY Car during the May 1985 superoutburst. From them we find that the superhump has a temperature of ∼8000K and an area of order half the size of the red dwarf or accretion disk. We also compare the behaviour during two simultaneous optical/IR observations. Whilst the light curves in the two pass bands are similar during one observation, in the other observation they show marked differences that may be due to a cool region in the outer disk.
