Today is the December solstice, marking an astronomical beginning of summer in the southern hemisphere and winter in the north. This photo was taken on the 17th of December 2022 at 12:30 local time, when the Sun was at its highest position in the sky here at latitude 63\u00b0N.\u00a0<\/p><\/div><\/div>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

To the left you can see the city of \u00d6stersund and to the right is Fr\u00f6s\u00f6n, a big island close to the city.<\/p>

Above Fr\u00f6s\u00f6n you can see a small cloud of smoke leaving the top of the island. That’s snow being produced by snow cannons at the local ski slope, Gustavsbergsbacken.\u00a0<\/p>

These tiny ice crystals produced by snow cannons are almost perfect in shape and have a tendency to be more likely to produce solar halos. Solar halos are more frequently visible close to ski resorts that have snow cannons producing these perfect ice crystals.<\/p>

This photo was also featured as Astronomy Picture Of the Day<\/a> at NASA on the 21th of December 2022, to read more about that feature follow this link –\u00a0https:\/\/apod.nasa.gov\/apod\/ap221221.html<\/a><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

Above you can see a video I made at the same time with my drone flying over lake Storsj\u00f6n closing in on the bridge between \u00d6stersund and Fr\u00f6s\u00f6n.<\/p>

This time of the year solar halos are more frequent during cold days when the air is filled with tiny ice crystals making sky phenomenon like this possible.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

Here’s another image of the same halo taken with my Nikon Z9<\/a>\u00a0camera and the\u00a0<\/span>Nikon Z 14-24mm f\/2,8 S<\/a>\u00a0lens.<\/p>
