We present observations of eight intermediate luminosity protostars and circumstellar disks in OMC-2 detected by SOFIA/FORCAST during the SOFIA short science phase. We combined the SOFIA/FORCAST observations with observations from the Spitzer Orion Molecular Cloud Survey, The Herschel Orion Protostar Survey, and ground-based data published in the literature in order to construct a spectral energy distribution for each object from the near-infrared to the submillimeter. The observed sources can be modeled as protostars with infalling envelopes heated by internal sources or as pre-main sequence stars surrounded by dusty disks. The reddest, most deeply embedded source (FIR 4) can be modeled as a 60 Lsun, Class 0 protostar with a predicted infall rate of 3E-4 Msun per year. One of the detected sources with an unusual SED may be a disk which is externally heated by other luminous sources in the Orion region.
