Understanding magnetometers


Recommended Posts

Hi guys, I've been reading many topics about magnetometers as a good indicador for aurora activity.


 I've been checking Kiruna and Tromsø  magnetometer, but I have no clue of what that information means, there are 3 lines, red, blue and green, reaching diferentes values... 

When is low, moderate or strong geomagnetic activity according to those values and what kind of info each line give us?

For Kiruna we look at the black line (X-component)

Scroll all the way down here to see how Kiruna classifies their K-scale: https://www.spaceweatherlive.com/en/help/the-kiruna-magnetometer

You take the highest and lowest X-value of today. Calculate the difference in nT and convert that to the K-indice for Kiruna with the table in the article I just linked to.
