Carlosboreal Posted March 4, 2016 Share Posted March 4, 2016 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? Thanks Link to comment Share on other sites More sharing options...
Marcel de Bont Posted March 4, 2016 Share Posted March 4, 2016 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. Link to comment Share on other sites More sharing options...
