Lightning is to blame, and we are crossing fingers for more favorable weather and luck in the future. There was unfortunately a data gap between February 21st (2006.052 18:00 UTC) - February 23rd (2006.054 00:00 UTC). Data with the new antenna is being published again after this gap. An updated log will be submitted to the IGS-CB shortly. As always we would like to acknowledge the assistance of the personnel from the Hartebeesthoek RAO in Krugersdorp in restoring operations so quickly. We apologize for any inconvenience this 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 Surface and Interior Focus Area - Science Mission Directorate. Best regards, -Oivind Ruud
