Pictures

Panoramic View - Northern Sky

2021-10-30 21:56 UT First faint indications of auroral activity. Faint arc developing in northern sky

2021-10-30 22:10 UT Faint auroral arc developing

2021-10-30 22:15 UT Auroral arc brightening.

2021-10-30 22:21 UT Activity increasing

2021-10-30 22:22 UT Activity building towards a peak

2021-10-30 22:23 UT Bright aurora but still close to horizon, movements fast

2021-10-30 22:24 UT Fast changes in aurora (1 min different from image above)

2021-10-30 22:29 UT Aurora with auroral rays to 10-12° altitude

2021-10-30 22:30 UT Aurora with auroral rays and fast moving curtain

2021-10-30 22:33 UT Aurora with fast moving curtains

2021-10-30 22:40 UT Aurora receding, but rays still evident to 10° altitude

2021-10-30 23:22 UT Aurora fading

2021-10-31 00:39 UT Aurora continuing to fade. Bright flash in NW Sky ( ? Iridian Flare or ? other bright satellite reflection)

2021-10-31 00:39 UT Aurora continuing to fade. Faint trail in N Sky ( Meteor ?)

All Sky View

2021-10-30 22:30 UT Completely clear sky. Aurora with auroral rays and fast moving curtains along northern horizon Telescope active and about to slew to IC 190 w/SN2021abko

Magnetometer Stack Plots (for reference)

Magnetometer Stack Plots from Scandinavia (ordered by latitude) H Component - 2021-10-30 / 2021-10-31 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)
