Observations of O/N2 Variations from the Ground During the Alaska Auroral Jets Rocket Campaign

During the Auroral Jets campaign period ground observations were made from Poker Flat and Fort Yukon Alaska using The Aerospace Corporation's 4-channel photometer system. Observations have been made from these sites for many years. However, the period of the launch on March 2, 2017 was particularly noteworthy for the well-defined periods of decreasing O/N₂followed by recovery. The complementary data set from this night is particularly rich as there was launches of two sounding rockets, and there existed a multitude of other instruments operating in support of the launches, including Fabry-Perot OI Redline and Greenline wind and temperatures. Here we will discuss the lifetime of the composition change in the context of the available data on that night, as well as previous observations of O/N₂ variations that we have reported on. A preliminary analysis of the results suggest, as was found in VISIONS, that the observed changes were not local but occurred at both sites that are separated by a degree of latitude.
