Magnetometer Stack Plots (for reference)

Magnetometer Stack Plots from Scandinavia (ordered by latitude) H Component - 2021-01-11 / 2021-01-12 Original data from Tromsø Geophysical Observatory (TGO), DTU Space (Technical University of Denmark) and Finnish Meteorological Institute (FMI, displayed on SpaceWeatherLive http://www.spaceweatherlive.com/en/auroral-activity/magnetometers). Note: Geomagnetometer activity at rvk (Rorvik, 64.95N), dob (Dombas, 62.07N), sol (Solund, 61.08N) and kar (Karmoy, 59.21N) stations are used as indicators for potential auroral activity that may be visible from my Observatory situated at latitude 57.32N  (Map of Stations)
