Visibility IV / V
The almost clear and calm frosty day drove the halo chaser to the outskirts of Hasamäki again in the hope of ice fog. Frost readings varied between 15 and 22 degrees depending on location. At Hasamäki, the scenery was completely obscured, but it seemed that the formation of crystals was weak. The fog was only close to the ground in a layer about 30-35 meters thick, and when the Sun was partly behind the clouds, the halosoot was modest. The icy mist was released by the drone, however, the moderate sub-side suns and the lower sun. There were also basic hugs in the upper clouds.
The main picture was taken 2 km from Hasamäe at a height of 90 meters. The second image is from the same point just above the fog cloud at 40 meters. Third is the wide-angle panorama from the same point as the first image. The fourth picture was taken 5.5 km from Hasamäe, where there was less fog. The location for the fifth photo is 12 km southwest of Hasamäe. It is included because it shows well how the weak northeast wind has carried the ice mist as a narrow strip more than 10 km from the snow cannons.
Figures 6 and 7 show the halves of the upper clouds as seen from the home village. The 180-degree panorama depicted in Figure 6 from Saimaa, which has received an ice sheet today, and Figure 7 is then a "traditional" stack of 20 images, from which nothing new was found compared to observations made with the naked eye.
