Aurora	Notes
Pictures Videos Summary Plot Magnetometer Stack Plots (for reference) Planetary K-Index Plot (for reference) Aurora Forecast, NOAA/Ovation (for reference)	- Brief aurora display localised to Scandinavia, but also in NE Scotland - Activity from around 20:15 to 21:15 UT close to northern horizon.    (Kp3, but locally up to Kp 7 in Sweden).  - Corresponding strong, brief peak observed in SAMNET's magnetometer data from Crooktree, Near Torphins (NE Scotland) - Bright meteor noted at 21:53h UT

Magnetometer Stack Plots (for reference)

Magnetometer Stack Plots from Scandinavia (ordered by latitude) H Component - 2017-11-24 / 2017-11-25 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)
