Magnetometers

Kiruna Magnetogram

This magnetogram gives you the values measured by the ground station of Kiruna (Sweden, Europa). For European middle latitude auroral activity the deflection in the magnetometer data should be more than 1300nT. If you are not located in Europe, please consult a magnetometer near your location for a more accurate representation of the current geomagnetic activity.

Disturbance Storm Time index

The Disturbance Storm Time (Dst) index is a measure of geomagnetic activity used to assess the severity of geomagnetic storms. It is expressed in nanoTeslas and is based on the average value of the horizontal component of the Earth's magnetic field measured at four near-equatorial geomagnetic observatories. It measures the growth and recovery of the ring current in the Earth's magnetosphere. The lower these values get, the more energy is stored in Earth's magnetosphere.

Magnetometer stackplots of TGO, DTU Space and FMI

Below are several magnetometers that are located in Norway, Denmark and Finland and are ranked according to their latitude. When a geomagnetic storm starts the most northern magnetometers will respond; when the geomagnetic storm strengthens the lower magnetometers will respond as well. Once the stations Dombås (DOB) and Solund (SOL) also react, as the magnetometer also drops, then in the European Middle Latitudes there is a chance that you'll see the aurora low in the northern horizon.

Data from Tromsø Geophysical Observatory (TGO), DTU Space (Technical University of Denmark) and Finnish Meteorological Institute (FMI).
