- GBT Spectrometer not available – As of October 1, 2015 the GBT spectrometer has been officially retired and is no longer available for use.
Since mid-February 2015 the GBT spectrometer has encountered errors which prevent it from being used for observations. Currently all staff efforts are being focused on VEGAS. We do not have a time estimate for when the GBT spectrometer will become available for observations.
