SOFIA Target of Opportunity Observations of Galactic Supernovae and Supernovae in Nearby Galaxies

We propose to conduct repeated SOFIA FLITECAM and FORCAST grism Target of Opportunity (ToO) observations of Galactic supernovae and supernovae in nearby galaxies that may occur during the SOFIA Cycle 5 observing period. Many of our FLITECAM objectives can be met for SNe with M_v < 14.0, while FORCAST objectives will require SNe in galaxies less than 1 Mpc distant. The scientific focus of the proposed observations is the determination of the temporal development of the ejecta and the nature of the interaction of the supernova radiation, ejecta, and blast wave both with each other and with the surrounding material.
