Category: GBT Observer Alert – Past

The GBT has returned to the regular full azimuth slew rate.

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!

The default TCal values used for standard calibration have been updated for the Ku-Band receiver. 

Three more azimuth wheels have been replaced during this summer maintenance period. Wheel inspection shows no advanced signs of fatigue in the remaining wheels. The restriction to 1/2 azimuth slew rate has been lifted and the GBT is now moving at 3/4 azimuth slew rate.

Data taken with the GBT during the period March 13th, 2023 @18:00 ET – May 25th, 2023 were not corrected properly for doppler tracking in the barycentric and LSR frames.

We encourage all observers to test the new installation prior to your observations.
