A strong display occurred on the night of the 11th and 12th of
April 2001.
Here are a few of my photos taken near Stirling, Scotland, between about 21:45 UT on the
11th April 2001 and 00:30 UT on the 12th April 2001.
Beautiful reds and greens in the NW. Jupiter is the "star"
in the lower part of the frame.
Taken during a period of generalised glow in the NE. It looks like
daytime, but there are stars visible!
A superb corona in the direction of Ursa Major. Changes in structure
were visible by the second.
A feature of the active period were "flames" of yellow
darting from the W horizon to the zenith. The photo unfortunately does not capture the
dynamics of this event.
