Observation Cycles

How is it decided what SOFIA observes?

Selection of German and International Observation Proposals

Before every new Observation Cycle, there are both a German and an American "Call for Proposals". German proposals are collected by the Deutsches SOFIA Institut and American and international proposals are collected by NASA/USRA. After the deadline, a German Time Allocation Committee (TAC) selects the best German proposals and an American Time Allocation Committee selects the best American and other international proposals.

Current Call for Proposals

There is no current Call for Proposals. The next call will occur before the end of Observation Cycle 8, which ends on 24th of April 2021.

TAC Results of Past Observation Cycles

The German SOFIA Cycle 8 Open Time call (deadline September 7, 2019) attracted 33 proposals for an initial total offer of 80 observing hours. The Cycle 8 TAC members met on October 7 to 9 at DSI/University of Stuttgart and evaluated the proposals. After a reevaluation of the available science hours, reconciliation with the US TAC results and program optimization, 4 proposals were selected as WILL DO (Category I), of which one is a ToO program. Another 4 proposals were selected as SHOULD DO (Category II), and 6 proposals as DO IF TIME (Category III). There were a total of 29.3 h assigned to the high priority schedule (Category I and II, excluding the ToO observation), while 32 h were assigned to the lower priority (Category III).

The German SOFIA Cycle 7 Open Time call (deadline September 8, 2018) attracted 33 proposals for an initial total offer of 70 observing hours. The Cycle 7 TAC members met on October 16 and 17 at Reston in the USA and evaluated the proposals. In summary, the TAC recommended 4 proposals as WILL DO (Category I), 5 proposals as SHOULD DO (Category II), and 14 proposals as DO IF TIME AVAILABLE (Category III). After a reevaluation of the available science hours with improved accounting for observatory overheads, and reconciliation with the US TAC results, there were a total of 45.2 h assigned to the high priority schedule (Category I and II), and 62.1 h assigned to the lower priority (Category III).

The SOFIA German Cycle 3 call for proposals (deadline July 18, 2014) generated 32 proposals. The SOFIA Time Allocation Committee (TAC) met at DSI/Univ. Stuttgart on September 17 and 18 to evaluate and rank the proposals by scientific merit.

The committee had the following members:

  • Prof. Dr. Dietrich Lemke, Chair (Max-Planck-Institut für Astronomie, Heidelberg)
  • Dr. Frank Bigiel (Institut für Theor. Astrophysik, Univ. Heidelberg)
  • Dr. Eike Guenther (Thüringer Landessternwarte, Tautenburg)
  • Dr. Mark Morris (Univ. of California Los Angeles, California)
  • Dr. Markus Nielbock (Max-Planck-Institut für Astronomie, Heidelberg)
  • Dr. Michael Olberg (Onsala Observatory, Sweden)
  • Dr. Nicola Schneider (Observatoire de Bordeaux, France)
  • Dr. Bringfried Stecklum (Thüringer Landessternwarte, Tautenburg)
  • Dr. Malcolm Walmsley (Arcetri Astrophysical Observatory, Florence, Italy)

The proposals were ranked in 5 categories:

  • A+ (excellent)
  • A- (very good)
  • B+ (good)
  • B- (fair)
  • C (poor)

Below we present tables for categories A+ (MUST DO), A- (DO with high priority), B+ (DO with lower priority). All of these proposals in the first 3 categories were awarded time, as listed. Proposals in category B- (DO if time) were not awarded time at this point. The targets in these proposals may be used as fillers, in case gaps occur in the flight plans. Proposals in category C were rejected.

The total available time for the German community in Cycle 3 is about 45 hours. It must be noted that many approved GREAT proposals request time which would require or benefit from a SOFIA deployment to the Southern Hemisphere. The time awarded here is therefore contingent on the GREAT instrument to be deployed to New Zealand, which is likely but still awaits final approval by NASA.

The SOFIA German Cycle 2 call for proposals (deadline June 29, 2013) generated 22 proposals. The SOFIA Time Allocation Committee (TAC) met at DSI/Univ. Stuttgart on September 17 and 18 to evaluate and rank the proposals by scientific merit.

The committee had the following members:

  • Prof. Dr. Dietrich Lemke, Chair (Max-Planck-Institut für Astronomie, Heidelberg)
  • Priv. Doz. Dr. Dominik J. Bomans (Ruhr-University Bochum)
  • Prof. Dr. Artie P. Hatzes (Thüringer Landessternwarte, Tautenburg)

  • Dr. Ralf Siebenmorgen (ESO, Garching)
  • Prof. Dr. Marco Spaans (Kapteyn Astronomical Institute, Groningen, The Netherlands)
  • Prof. Dr. Harold W. Yorke (Jet Propulsion Laboratory, Pasadena, California)

The proposals have been ranked into 5 categories:

  • category A (MUST DO)
  • category B (SHOULD DO)
  • category C (DO IF TIME)
  • category D (FILLER)
  • category E (DON'T DO)

Below, we present 3 tables for category A,B and C. The total open time available for the German community is about 42 hours, including a few hours for FIFI-LS science verification.

The SOFIA German Cycle 1 call for proposals (deadline March 2, 2012) generated 39 proposals, asking for a total of 200+ hours observing time. The SOFIA Time Allocation Committee (TAC) met at DSI/Univ. Stuttgart on April 16 and 17 to evaluate and rank the proposals by scientific merit.

The committee had the following members:

  • Prof. Dr. Michael Grewing, Chair (Univ. Tübingen, Germany)
  • Dr. Pierre Cox (IRAM Grenoble, France)
  • Dr. Andy Harris (Univ. Maryland, USA)
  • Dr. Frank Israel (Leiden Observatory, The Netherlands)
  • Dr. Hans-Ulrich Käufl (ESO, Garching)
  • Dr. Jesús Martin-Pintado (Centro de Astrobiologia, Madrid, Spain)
  • Dr. Katharina Schreyer (Univ. Jena, Germany)
  • Dr. Bingfried Stecklum (Landessternwarte Thüringen, Tautenburg, Germany)

The committee was asked to rank the proposal into 3 main categories:

  • category A (MUST DO)
  • category B (CAN DO, if time)
  • category C (DON'T DO in this cycle)

Interestingly, the panel decided to introduce a 4th category, intermediate between A and B, labelled A/B (SHOULD DO, if at all possible).

Below, we present 3 tables, one for category A, one for category A/B, and one for category B. The order of appearance of the selected proposals in each table is alphabetical and does not represent a ranked sequence. The total open time available for the German community is about 35 hours.

Update: On recommendation from the SOFIA Users Group (SUG) the Science Mission Operations has decided to publish the time awarded for each proposal. Thus, we now list the awarded hours by the TAC in the last column.

While we will make every effort to schedule all category A proposals, in the end it all depends if they can be fitted into an optimised flight schedule. Therefore it is conceivable that a category A/B or even B proposal will make its way into the schedule, while a more meritorious A proposal may have to be left out. Note that we plan to have a SOFIA deployment to the southern hemisphere in July 2013 (most likely Christchurch, New Zealand).


Thank you very much for your interest in SOFIA observations.

The DSI is pleased to announce the results of the review of the proposals submitted in response to the German Call for Proposals for SOFIA Science Demonstration Time.

Members of the Review Panel

  • Prof. Dr. Michael Grewing, Chair (Tübingen)
  • Prof. Dr. Ed Churchwell (Madison, WI)
  • Prof. Dr. Alain Omont (IAP, Paris)

Highest Ranked Proposals

Of the 22 proposals submitted, 18 requested observing time with GREAT and 4 requested observing time with FORCAST.

The following table lists the 8 successful proposals with the highest ranking. Every effort will be made to schedule these proposals for execution. The last column of the table provides an estimate of the effective observing time (including a realistic overhead of 100% for GREAT and 50% for FORCAST) granted to the proposals. The observing times listed are preliminary and subject to some change. The effective overhead will be finalized during the scheduling process

Second highest ranked proposals

The following table lists proposals in the group of the second highest ranking. Given the complexity of efficient flight planning and the limited observing time it is expected that only several but not all of these proposals will be scheduled. The observing times listed are preliminary and subject to some change. The effective overhead will be finalized during the scheduling process.

The abstracts of actually scheduled proposals will be provided in due time.

Phase 2 Procedure

Both groups of proposals above are eligible to enter Phase 2 of the proposal procedure. For Phase 2, the PIs of these proposals will be contacted by the SMO staff. Deadline for Phase 2 for FORCAST proposals is April 29, for GREAT proposals May 13.
