The Norfolk Island magnetometer has been out of service since 2017/12/13.  
Work is ongoing to return the magnetometer to service, with a new data 
acquisition system scheduled to be installed on 2023/09/13. 

System: MDAS v1.0
Sensor: Bartington Mag03
Data Acquisition System: MDAS v1.0 
Logging software: BECA v1.0
Operator: Bureau of Meteorology
Station: Norfolk Island
Station Code: NLK
IUWDS Station Code:	87301
Sensor Orientation: HDZ
Data type identifier: K
Coordinates: -29.04078, 167.96272, 143 m ASL
Sampling Frequency: 5 Hz

The sampling frequency is changing to 5 Hz from 1 Hz with the data 
acquisition system upgrade.

Intermittent environmental noise has been found in the NLK magnetometer data.  
Because of the frequency of the noise and the size of some of the noise spikes,
the NLK data can't be considered as operational. SW Networks is investigating 
the source of the noise.
