Kiruna magnetometer
This magnetometer gives you the values of the Kiruna station in Sweden, Europe. It is often used in Europe to see if you can see an auroral display or not. In America other magnetometers are used like the Canopus oval. But how do we read this plot? For auroral viewing on middle latitudes the Bx value (black line) should be below -1000, for realy good auroral viewing -1500 or more is required.
To show you it's possible on the middle latitudes we'll give you this plot of october 2003 when the shocks arrived of a X17 and X11 solar flare.
