A review:
Today, November 6th, 2020, is the 19th anniversary of a grandiose natural spectacle: the great aurora borealis on the morning of November 6th, 2001 over Saxony and Europe. At 4 a.m., the main activity was very unusual in the morning, the shock front hit earth's magnetic field around 1 a.m. At that time I was woken from sleep by a star friend by phone, woke another one and am still grateful for that ...
The cause was an X10 flare (!) on the sun, the KP index was 9 ...! A G4 storm shook the earth's magnetic field tremendously, the DST index was -292 nT, the Bz value was -79.5 nT. Values that one could only dream of in the past 24th cycle. In view of the now increasing solar activity with AR 2781 and hopefully other large groups, one can hope to experience something similar again. Especially since photo technology is completely different nowadays. I mean the northern lights in our latitudes ...
The picture was taken on the Lerchenberg near Börnchen in Saxony. In the background the lights of Dresden. To the left of the tree the Mt. Keulenberg near Pulsnitz with the beacon (red dot). Won't forget that.
PRAKTICA MTL 5B, Pentacon 1.8 / 50, 60s, Kodak E 200 slide film.
