SOFIA Observing Cycle 4
Cycle 4 Call for Proposal Phase 1 completed
The submission deadline for Cycle 4 observation proposals has passed. The peer review processes for both US and German queues has been completed. See observation times awarded to proposals by the Time Allocation Committee.
Call for German Proposals
The Stratospheric Observatory for Infrared Astronomy (SOFIA) is pleased to invite proposals for its fourth regular observation cycle which is planned to take place from February 2016 through January 2017.
About twice the amount of observing time is offered compared to the previous cycle.
The official Call for German Proposals document is available for download from this website. It containts all necessary information in order to prepare and submit a proposal for scientific observations during Cycle 4.
If you are preparing a SOFIA Cycle 4 Observing proposal using HAWC+, please note the following critical information.
The correct overheads for HAWC+ were incorporated into v2_8_3 of the SOFIA Proposal Tool (SPT), released on June 4, 2015. Earlier versions of SPT significantly understimate these overheads. Therefore users proposing HAWC+ observations should use SPT v2_8_3 to prepare and submit their proposals.
Unfortunately, this change was not included in the list of formal updates released on June 8, 2015 . We apologize for the late notice, and the inconvenience this may cause. If you have any questions, please contact the SOFIA help desk at firstname.lastname@example.org

Cycle 4 Schedule
The nominal schedule for the Cycle 4 observing program is as follows:
|May 7, 2015||Release of Call for German Proposals.|
|June 16, 2015||Call for Proposals update|
|July 10, 2015, 23:59 CEST||Proposal Submission deadline|

|Feb 2015 - Jan 2017||Cycle 4 observing period|
For Cycle 4, the following instruments will be available: EXES, FIFI-LS, FLITECAM, FORCAST, FPI+, GREAT, HAWC+, HIPO and the FLITECAM/HIPO combination. The instrument modes available for Cycle 4 observations are listed in the Call for Proposals and described in details in the Observer's Handbook. The instrument properties are summarized on the instrument pages.
Reserved Observations Catalogs (ROCs)
Summary tables containing the reserved observations for each instrument are included as appendices in the Call for Proposals. Generally, these may not be proposed for in Cycle 4. The policies are described in Section 1.7.1 of the Call for Proposals document.
Duplications of existing observations, or of observations approved for Cycle 3 but not yet executed, need to be justified explicitly. Proposers should search the SOFIA Science Archive for completed observations and the AOR Search page for approved Cycle 3 observations to check for potential duplications. As noted above, the ROC tables in the Call for Proposals should also be checked for disallowed observations.
Exposure Time Estimation
- EXES - exposure times should be obtained from the on-line calculator for EXES observations, maintained by the Instrument PI, Matthew Richter (UC Davis).
- FIFI-LS on-line time estimator.
- FLITECAM imaging - on-line calculator, SITE.
- FLITECAM grism observation calculator.
- FORCAST imaging - on-line calculator, SITE.
- FORCAST grism observation calculator.
- FPI+ - on-line calculator, SITE.
- GREAT - exposure times should be calculated using the GREAT on-line time estimator. The calculations are based on the , which also contains detailed information about the instrument. Note that information about upGREAT has not been incorporated into the exposure time estimator yet.
- HAWC+ - on-line calculator, SITE.
- HIPO - exposure times may be estimated using the information in the Observer's Handbook. Since HIPO and the FLITECAM/HIPO combination are considered special purpose instruments, detailed planning of observations should be carried out in consultation with the Instrument PI, Edward Dunham (Lowell Observatory).
