Dear Colleagues,

As mentioned in [IGSSTATION-248], the AOAD/M_T antenna at the Hartebeesthoek RAO in
Krugersdorp, South Africa (HRAO) has been replaced with a new Ashtech ASH701945C_M
antenna on November 19th, 2004 (2004.324). 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
