Aurora Borealis or Northern Lights are the
result of interaction between charged particles
from the Sun and the Earth's upper atmosphere.
The Earth's magnetic field concentrates auroral
activity in rings around the magnetic poles as
seen in the auroral activity maps on the web
site of the
Space Environment Center (SEC) of the
National Oceanic and Atmospheric Administration
(NOAA).
Although Iceland is virtually always in the
zone where the Northern Lights are visible, a
lot of luck is necessary to see or photograph
them on a short trip as they depend on both
high solar activity and good Icelandic weather.
These photos were taken from the town of
Saudarkrokur in northern Iceland over the
period Feb. 13-15. Exposures were about 20
seconds each on Kodak PPF 400 and Fuji 800 35mm
negative film using a 35mm f/3.3 lens.
