Displays

Fairbanks was treated to a nice odd radius lunar display on the morning of December 31, 2009. The image above consists of four of my frames stacked by Jari Luomanen. I hope to have more photos and information on the…

Eetu Saarti photographed this double ellipse in the new year’s night. The phenomenon lasted for 15 minutes and was followed immediately by 22° halo. Click the image to see a gallery with two more photos.

The halo season has started in the Czech Republic, too. The above image was shot by Jiri Papez on 13 December in Dvoracky ski center. Nearby on Lysa hora the display was captured by the Hydronet.cz camera ( 1 ).

This display was photographed on 4th December by Liisa Eronen in Kulho, Kontiolahti, Finland. The temperature was around -4°C. Nearest ski center is located about 10 km away, so most likely this was caused by snow guns.

Below is the promised translation of the Arctowski’s famous observation in the Antarctic. Thanks for Frank Le Blancq for translating. In hard brackets are some clarifications by Frank. Translation of the whole double page of the book ( 1 )…

Diamond dust started falling around Himos, Finland on 14 December, and kept on for 4 consecutive days. This display with subparhelia was shot on the first day. A full parhelic circle was also observed, and for a short time, part…

One would think that such a demanding halo as Liljequist parhelia would need the best possible swarm to be seen. While that may be true in halo displays from natural light sources, with spotlight it is a different story. Here…

Last winter I noticed one sided 22° halo on ice surface ( 1 ). This winter there has been a couple of more cases with varying degree of one-sidedness. The displays seem to be a rule on even surfaces, either…

Last Tuesday we were hunting diamond dust halos with Ágnes Kiricsi at Himos ski resort. Driving around took us to lake Päijänne, which had just started freezing. The ice was full of ice ferns, but one spot was quite clean…
