SOFIA Target of Opportunity Observations of Supernovae in Nearby (D < 5 Mpc) Galaxies

We propose to conduct repeated SOFIA FLITECAM and FORCAST grism Target of Opportunity (ToO) observations of supernovae in nearby (D < 5 Mpc) galaxies that may occur during the SOFIA Cycle 3 observing period. The objectives of the observations are to determine the temporal development of the ejecta and the nature of the interaction of the supernova radiation, ejecta, and blast wave with the surrounding material.
