SOFIA Cycle 2 Call for Proposals Released Release Date: Apr 29, 2013 Proposal Due: June 28, 2013 The Stratospheric Observatory For Infrared Astronomy (SOFIA) Science Center is pleased to announce the Cycle 2 Call for Proposals for SOFIA. This Call solicits proposals for approximately 175 hours of science observations using SOFIA during the calendar year 2014. The deadline for Cycle 2 proposal submission is June 28, 2013. Instruments offered for Cycle 2 observations are: (1) FLITECAM near-IR camera including its grism modes, (2) FORCAST mid-IR camera including its grism modes, (3) GREAT far-IR heterodyne spectrometer, (4) HIPO optical high-speed photometer, and (5) the combination of FLITECAM with HIPO ("FLIPO"). The EXES mid-IR spectrometer and the FIFI-LS far-IR imaging Spectrometer, which are expected to be commissioned in 2014, are for the first time available as shared-risk for a limited amount of Guest Investigator observations. Information about preparation and submission of observing proposals is available at the Cycle 2 webpage: http://www.sofia.usra.edu/Science/proposals/cycle2/ The instrument capabilities are described in the SOFIA Observer's Handbook for Cycle 2, released with this call for proposals. An update to the Call for Proposals is scheduled on June 1, 2013. The update will disseminate knowledge about observatory and instrument capabilities gained from the analysis of data from commissioning flights currently underway. No major changes are anticipated to the observatory capabilities, as described in the current call for Proposals document and in the SOFIA Observer’s Handbook for Cycle 2. For questions and assistance, please contact the SOFIA Help Desk at sofia_help@sofia.usra.edu. This call is open to all qualified astronomers, world-wide, in the U.S. and outside the U.S., except for those currently affiliated with German institutions. Astronomers with a German professional affiliation may participate through the German Aerospace Center DLR and the Deutsches SOFIA Institut Cycle 2 Call which will be released later this month. We look forward to your participation in this exciting new research opportunity. Erick Young Director of SOFIA Science Mission Operations
