An updated log has been submitted to the IGS. We would like to acknowledge the help and assistance from the HRAO personnel in restoring operations quickly. This updated log also reflects corrected dates for INTERNAL clock and EXTERNAL (H-Maser) frequency standard periods to the best of our knowledge. And lastly, the antenna entries have been changed to reflect that there was never a radome installed over any antenna at this site. We apologize for any inconvenience this may cause and for the delay in submitting this notification. Except for data collected while the old, broken antenna was still in place, all backlogged data will be published. Maintenance and operations of the HRAO station is a collaborative effort supported by JPL, UNAVCO, and the Hartebeesthoek RAO in Krugersdorp, with funding provided by NASA's Earth Science Enterprise. Best regards, -Oivind Ruud
