28° halo in Juva

27.9. From the display where, according to Petri Martikainen who made the observation, the eye could only see a "bland ring", several more halos emerged when stacked. The most notable is the 28° halo, which is a very rare visitor of the white sky. In Taivaanvahti only four cases have been reported from Finland. A statistical comparison has yet to be made, but the strong feeling is that 2023 has been an exceptionally good halo year.

Northern lights on the night before Monday

26.9. Observations have been obtained mainly from the southern half of our country. Here are Pirjo Koske and Tom Eklund's pictures of Laitila and Akaa. That was already the case the fourth strong northern lights show in September. "This repos season feels pretty wild at the moment, we're only going to September and we've repeatedly had quite a treat even as far south as this," says Timo Alanko .

Good northern lights again

19.9. September has been favorable in terms of northern lights. The third bigger show of the month arrived on 18/19.9. Sightings have arrived from the entire length of the country, from Enontekiö to Helsinki. Attached are Hanna Kanniala's and Mikko Lemola's pictures of Ii and Kouvola.

A fog arc in Hämeenkyrö

19.9. Mervi Ketola photographed an exceptionally spectacular arc of fog on Hämeenkyrö's Heinijärvi on Sunday. The series of images shows that the fog started to recede from behind the photographer. This is the optimal situation for the creation of a beautiful phenomenon when the sun shines brightly into the fog ahead.

Fortunately, there was no rush today with the cloudiness, so I finally got to test Samyang's wide angle and the 6D Mark II in halo photography. You can get a pretty good result with that combination, but the fisheye will definitely still be added to the purchase list. In itself, it's a shame that only basic pretzels were available again.

In a couple of nights it was possible to look at Jupiter again. On October 2, even while filming the video, bigger and brighter light spots or spots than usual attracted attention. I had also filmed on September 25, which can be compared; bottom picture.

There was a special ring on the sun. It doesn't really look like just a halo. The morning picture has a clearer halo ring. In the afternoon there was a browner ring and wide. Either would look like a halo from above. I do not know: D

The weather was bad all week. Rain and strong wind. Nothing to observe. I'm usually a night owl and a morning sleeper :) I happened to wake up and noticed that it's even light. Had to go check if anything was visible. The rim of the moon was visible along with Jupiter. There is a line in that one picture. The plane might have missed it. The clouds sometimes obscured the view. The hands shook such a star line in that picture. I did come to a few others. Couldn't find what star it was. You can only get a few stars/planets in pictures with this phone.

Säätila gave its challenge to observation. The Moon was at 43° elevation, with Jupiter right next to it. However, the seeing between the cloud rafts is moderate, so it was a shame to leave the drawing unfinished.

I'm only posting this observation here now because I "mistaked" shooting halos all the way to stacks, after which I ran into technical problems with Halostack. (For example, you could write your own comment about them.) I have previously made a few photo stacks of halo images with a "hand game", which were not originally thought to be stacked, but now I shot a series of images for the stack. Photo 3: in the afternoon I noticed a faint halo arc above the Sun, and took a stack of about 30 pictures of it (after that the Sun had time to pass out of the obscurator). However, tuning the tripod a...
