The deadline for submitting proposals is June 28, 2013. Proposal selections will be announced in September 2013. Details of the Cycle 2 Call for Proposals can be found at:

SOFIA is a 2.7m telescope, with an effective, unvignetted, diameter of 2.5m, housed in a Boeing 747-SP aircraft. Observations are typically carried out at altitudes between 11.9 km (39,000 ft) and 13.7 km (45,000 ft.). These altitudes place the observatory above up to 99.8% of the obscuring atmospheric water vapor. There are six observatory instruments offered in this Call, which cover the range 0.3-250 microns.
