A new IGS log will be submitted shortly. This new log will also reflect corrected dates for INTERNAL clock and EXTERNAL (H-Maser) frequency standard periods, and to reflect that there was never a radome installed over any antenna at this site. Data publishing is temporarily halted till we can ascertain the correct replacement antenna model for RINEX headers and IGS log. Except for data collected while the old, broken antenna was still in place, all backlogged data will be published. We apologize for any inconvenience this outage may cause. 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
