[IGSSTATION-5464] ONSA: maitennance/Antenna remove-restore / data

[Swepos Driften]

Author: Erik Katrin

Dear Colleagues, 

ONSA station was unavailable between UTC 06:00 and UTC 08:00 on July 4 (day 185) due to maintenance.
The antenna and radom was removed and restored, and the microwave absorbing material (Eccosorb TM)around the antenna was renewed.
Due to the renewal of the Eccosorb, it is possible that a shift in position will appear in time series at the date for the maintenance.

We apologize for the inconvenience of this outage. 

Best Regards, 
Erik Katrin
