Panoramic View - Northern Sky

2022-02-04 18:09 UT Auroral rays faintly visible in twilight sky

2022-02-04 18:30 UT Faint auroral arc developing with rays to 15 deg altitude

2022-02-04 18:53 UT Aurora arc with faint curtains & rays

2022-02-04 19:46 UT Auroral arc with rays /moving curtain in NNW sky

2022-02-04 20:09 UT Auroral arc. Bright transient point source in NW-WNW sky at 25 deg altitude in this frame alone

2022-02-04 20:21 UT Auroral arc to 9 deg altitude,  with moving curtain in NNW sky

2022-02-04 20:50 UT Auroral arc to 10 deg altitude

2022-02-04 21:02 UT Auroral arc to 11 deg altitude. Sudden appearance of multiple rays across entire length of arc (something brewing !)

2022-02-04 21:06 UT Aurora arc to 12 deg altiude. Peak activity starting Rays in NNW sky with bright auroral activity developing in N-NNE sky.

2022-02-04 21:07 UT Auroral arc with mutiple rays.High point just west of north.  Bright auroral light in N-NNE sky. Peak activity

2022-02-04 21:10 UT Double auroral arc. Significant activity on lower one extending from NNE to NW

2022-02-04 21:13 UT Bright acivity in NNW Sky. Broad upper arc with its high point lying 10 deg east of north

2022-02-04 21:37 UT Broad aurora arc, high point moved just west of north., fairly diffuse

2022-02-04 21:51 UT Aurora arc gradually descending and fading

2022-02-04 22:14 UT Aurora activity fading Activity temporarily died away between 22:20 and 23:20 UT

2022-02-04 23:25 UT Increase in aurora activity again in NNW sky

2022-02-04 23:32 UT. Auroral activity with rays to 12 deg altitude in NNW sky

2022-02-04 23:37 UT Auroral activity with rays to 12-14 deg altitude in N sky

2022-02-04 23:55 UT Auroral activity declined significantly but continuing very weak and low down along NNW to NNE horizon until 01:00 UT (2022-02-05)

Magnetometer Stack Plots (for reference)

Magnetometer Stack Plots from Scandinavia (ordered by latitude) H Component - 2022-02-04 / 2022-02-05 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)
