Green Bank Observatory 2017A Science Program

A total of 70 proposals requesting NSF funded “open skies” time were submitted to the Green Bank Observatory’s Robert C. Byrd Green Bank Telescope (GBT) were received for the August 1, 2016 deadline for semester 17A.  The table below summarizes the approved observing programs for the GBT.  Listed are the PI name, proposal ID, proposal title, maximum hours approved and proposal type (Regular, Triggered, Large or External).  Proposals from previous semesters that were awarded time in the 17A semester are included.  The table also includes HSA and GMVA proposals that were awarded time on the GBT as a VLBI station as well as proposal accepted via external agreements with CHANDRA, Hubble Space Telescope, FERMI and Swift.

For each approved program, the Proposal Finder Tool will have access to its author, title, abstract and total approved hours.
