Welcome to the home of the Magnetometer Array for New Zealand Aotearoa (MANA), a part of Solar Tsunamis. The MANA network is made up of five magnetic field measurement sites across Aotearoa New Zealand, accompanying the Earth Sciences New Zealand geomagnetic observatory site at Eyrewell.

The main goal of the MANA network is to provide a set of magnetic field measurements to observe space weather effects across the country. Large rapid variations in the magnetic field occur during geomagnetic storms (large storms in the Earth’s magnetic field in response to the arrival of solar storms.) These rapid variations can induce hazardous geomagnetically induced currents (GIC) in national infrastructure, such as power-grids and pipelines, which has the potential to cause damage. We in the Solar Tsunamis project study these magnetic field variations to help mitigate damage. Large magnetic disturbances can also indicate that the southern lights (aurora australis) have a high probability of being visible from Aoteroa New Zealand.

Please familiarise yourself with the network specifications and the Rules of the Road if you wish to use data from the MANA network.
