The Green Bank Observatory has finished the process of upgrading to Red Hat 8 (RH8). Observations can again be done with either machine Ariel or Titania!
Observing: Please use Ariel or Titania only when actively observing with the GBT (no data processing) and please remember to shut down your observing applications (AstrID, CLEO etc.) when your observing session is finished.
Data processing: Over the next few weeks, the remaining RH7 machines at GBO will be migrated to RH8. For data reduction, we will support running both RH7 and RH8 versions of data processing software that is supported by the GBO Software Development Division (SDD) until all machines are at RH8. Details about the status of our data reduction machines are available at:
