As I am sure has been noticed, there was an abrupt change in
the reference frequency beginning at -roughly- 15:00 UTC, DOY 291
(October 18).

I have received verification that the external frequency reference at
Kokee Park,
a Sigma-Tau H-maser, had failed and a backup standard put in its place.

An updated sitelog will be forwarded to the IGSCB.

Best regards,
