startling display at Tampere, Finland was experienced by Jari
Luomanen (site) on 7th March ’04.
The halo forming crystals are called diamond dust and
were in the nearby cold air rather than high-level cirrus cloud.
Individual ice crystal glints are visible. “That particular
image is very dear to me: it was taken during the absolute peak of
the display that really didn't last all that long. Just as I took
the image I simply had to extend my arm towards the upper
tangent arc to try and see whether I could touch it, to stir the crystal
swarm just a bit. I was able to stir the specks of
light with my hand. I'll never forget it.” ©2004,
