In the Japanese IGS station CCJ2 (DOMES:21732M002),
the configuration of the usage of the clock in the receiver changed
from the receiver's internal to the external Cs frequency standard
at the following time.
February 16th (Fri) 00:00UT
(The Cs frequency standard in CCJ2 is now stable.)
The site log of CCJ2 will be updated later.
[IGSSTATION-7114] - 2017-09-01 (19/09/2017)
The IGS site CCJ2 has been experiencing data outage since 2017-09-01T01:02Z.
The cause of this outage is under investigation.
[IGSSTATION-7115] - 2017-09-04 (19/09/2017)
In the Japanese IGS station CCJ2, the configuration of the usage of the clock in the receiver changed at the following time
from the external Cs frequency standard to the receiver's internal.
September 1st (Friday) 10:52UT
It stormed at the Chichijima Island (in Bonin Islands) on September 1st by a typhoon, and an electric power stoppage occurred in CCJ2.
After a recovery of the electric power, it seems that the Cs frequency standard became unstable.
The usage of the receiver's internal clock will continue for a while, and we will investigate CCJ2 in next November.
The site log of CCJ2 will be updated later.
