3. Cycle 4

Cycle 4 observations will take place between 1 February, 2016 and 31 January 2017. The observations will take place in a number of Science Flight Campaigns over the duration of the cycle. The campaigns will be interspersed with aircraft maintenance and instrument commissioning. Commissioning of upGREAT, the multi-beam heterodyne receiver, and the far infrared camera and polarimeter HAWC+ are ongoing in 2015 and 2016. These new capabilities are offered in Cycle 4, contingent on the success of commissioning activities. A single Southern Hemisphere observing series with up to two instruments is under consideration for the Cycle 4 time period, nominally in the summer of 2017.

For Cycle 4, the available instruments will be the mid-infrared high-resolution spectrograph EXES, the integral-field far-infrared spectrometer FIFI-LS, the near-IR camera FLITECAM, including its grism modes, the mid-infrared camera FORCAST, including its grism modes, the focal plane CCD imager FPI, in science mode, the heterodyne spectrometer GREAT, including the seven-beam receiver array upGREAT, the high-speed optical photometer HIPO, and the far-IR camera and polarimeter HAWC+. The instrument capabilities, the available modes, and the resulting performance specifications of the telescope are described in later sections.

Proposals are being solicited for the Cycle 4 SOFIA flights by USRA on behalf of NASA.
