2022a Joint Observations with SOFIA

Joint Observations with GBO and SOFIA

This agreement is only between the Green Bank Observatory (GBO) and SOFIA.  It does not apply to any of the NRAO instruments:  VLA, VLBA, ALMA.

By agreement between the GBO and the URSA, SOFIA will be able to award time on the Green Bank Telescope (GBT) to highly ranked proposals that request time on both SOFIA and the GBT. GBO has offered up to 5% of the available open skies time on the Green Bank Telescope (GBT) for allocation by the SOFIA Time Allocation Committee (TAC).
