A spring-starter in Finland

On 25th March a relatively small high-cloud area swept over Southern Finland and produced a fine halo for observers in Helsinki, Espoo, Turku and Riihimaki. In Riihimaki the upper Lowitz arc was continuously in the sky for over three hours. In addition to Lowitz, there were also pyramidal crystal halos (9 halo/column arc?, 24 lower plate arcs, 18 plate arcs), helic arc and Wegener anthelic arc.

The photograph above is taken by Jukka Ruoskanen, and more photographs can be found here. In Helsinki the display was photographed by Marko Riikonen, in Espoo by Panu Lahtinen and Timo Kuhmonen and in Turku by Ismo Luukkonen

Upper Lowitz arc in Germany



On February 21, Wolfgang Hamburg was on holiday in the Erzgebirge, but rather had snow there. Around noon, the cirrus clouds which already had caused an unusual halo activity in Bavaria (see one thread below), arrived at his position in Mulda. So between 1 and 1.30 pm, Wolfgang Hamburg also observed unusually bright sundogs followed by a beautiful display showing Parry arc and upper Lowitz arc. The enhancement of the unsharp mask shows the arc in the "Chinese eye" formed by the halos.

Lunar display in France with 9° halo and Lowitz arcs


On the evening of 30 October 2006, I saw this lunar display in the west of France, close to Nantes. The photos were taken between 18h and 21h UT, the moon elevation was between 19 and 24 degrees.


A lot of halos were visible, including 9° halo, upper and lower Lowitz arc and a bright upper suncave Parry arc.

The orange colour of the sky is due to a strong light pollution. The images have been processed to reduce this effect and unsharp mask has been applied to enhance the halos. I got also nice displays the 2 previous days.

More images of the display here: 1, 2, 3.
