Abstract

We have repaired and reflown an existing sounding rocket payload to observe the OVI 1032 Å, 1038 Å emission doublet from a non-radiative shock in the NE section of the Cygnus Loop supernova remnant. We will analyze the images to determine the distance between the OVI-emitting gas and the shock front in visible light, as well as measuring the morphology of OVI across the shock. This will provide a measure of the temperature equilibration length, which can then be used to constrain models of the physical processes causing temperature equilibrium of charged particles in the hot shocked gas of the interstellar medium.
