Communications problems continue to plague HOLM. We have be unable to retrieve data since Day 339 (December 5). As yet we have also been unable to get our onsite contact to investigate the problem further. I will advise when more is known.

After a 4 month communication outage since January 20 and repeated repair attempts, NorthwesTel has finally repaired the telephone line at HOLM and regular data delivery has resumed. Due to the low storage capacity of the Ashtech Micro-Z receiver, data could not be recovered for Days 020-050
In the process of tearing down the municipal garage where our GPS and tide gauge equipment was located, the interior room our gear was in was left standing by itself with little support around it. We were planning to remove our equipment this weekend and install it in the neighbouring garage next week when the new antenna cable arrives.
Unfortunately, we were too late. The room was just blown down about an hour ago by 80 kph winds. The site is now off-line. The monument and antenna should be fine but we expect the GPS receiver and comms equipment were damaged in the collapse. Our local contact will investigate further when safe to do so.
Our own technician will be arriving next week with a replacement receiver and modem and will reinstall the gear in the neighbouring garage. I will advise when the site is back on-line.
As notified in IGSSTATION Mail 5762, another power outage occurred at HOLM. Data was lost from 20:22:30 on Day 126 (May 6) to 17:43:00 on Day 127 (May 7).
There was an unexpected power outage at the HOLM site. Data was lost from 16:23:30 on Day 120 (April 30) to 17:26:00 on Day 121 (May 1).
Note that a further, more extended, power outage is expected in the next month or two due to the need to move our GPS receiver and tide gauge equipment to the building next door.
