[IGSSTATION-6796] - 2016-09-23 (04/10/2016)

Due to instrumentation work at HOLB, power was compromised, resulting in a permanent data gap from 2016-09-21T19:07:00Z to 2016-09-21T22:45:00Z.

There was also a loss of communication, and consequently a delay in data postings. This backlog of 30 sec and high rate data is now in the process of being retrieved and should be complete by the end of today.

[IGSSTATION-6657] - 2016-05-21 (24/05/2016)

Please be advised that beginning on D2016-131 there has been a degrade in the data quality at station HOLB. We are currently assessing the situation to determine the source of the problem and will provide an update as soon as possible.

[IGSSTATION-5942] - 2014-09-03 (03/09/2014)

Both the receiver and antenna had to be replaced at HOLB. As well the height of the antenna has changed.

There is a permanent data gap at this site from 2014-08-03T20:10:30Z to 2014-08-27T21:05:00Z.

An updated site log has been submitted to the CB

[IGSSTATION-5921] - 2014-08-18 (20/08/2014)

Further to IGSSTATION-5894, it has been discovered that a lightning strike likely affected the GPS infrastructure and initial tests suggest damage to the receiver. I’m therefore certain that there will be no data recovery after August 3 (2014-215). A site visit will be scheduled in the next two weeks to undertake necessary repairs.

[IGSSTATION-5894] - 2014-08-05:We are experiencing communication problems to our site at HOLB. The last data was on 2014-215 (August 3) @19:59:30 UT. Will send an Advisory once the site is again active. We expect there to be no loss of data.
