Half-sky auroras

23.3.2023 at 21.55 - 23.30 - Nurmijärvi (III)
Kari Hassinen, Keski-Uudenmaan Altair

The beginning of the northern lights show was very quiet, and after taking a few pictures I waited inside the car for a possible increase in activity. The wait was rewarded after almost an hour of waiting, and for about 45 minutes the strength, direction and extent of the repos varied constantly. Watching and filming ended when the activity faded and at the same time the abundant fog formed on the surface of the earth.

The weather started to gradually change from clear to cloudy in the south with the approaching low pressure. In that connection, a 22 degree tire was visible for a while.

About an hour after sunrise, a side sun on the right began to form in the sky, which gradually brightened. Then the 22-degree curve also started to take shape, and the "end result" can be seen in the main picture. The side sun photo was taken first, and the main photo about half an hour after that.

I noticed a 22-degree tire in the grocery store parking lot when I entered the store. When I left the store, I couldn't see the tire anymore, at least with the naked eye, but instead I could see the side suns - the left (pictured) better and the right very weak.

In the morning it was 10 degrees below zero and there were wonderful colors at sunrise. There were many kinds of clouds and cloud layers, and the skyscape was constantly changing on the horizon. For a while, a faint pillar of the sun was also visible.

The rim of the moon was visible very clearly for a while. However, the brightest phase had time to pass before I could get the camera and get to the shooting location.

Kari Hassinen, Keski-Uudenmaan Altair

I photographed Jupiter and its largest moons for the first time when they were suitably east and well visible from my backyard. Moons in the picture from left to right: Europa, Io, Ganymede, Callisto.

The full moon shone magnificently through the thin veil of clouds. Near the horizon, the Moon was reddish-yellow, and within half an hour the color faded to gray-white.

During the lunch break, a ring of 22 degrees had formed in the sky, which then dissipated very quickly after noticing it.

Moon

Kari Hassinen, Keski-Uudenmaan Altair

The waxing Moon (86% illuminated) was nicely visible through the gap formed by the branches and leaves of the maple tree. I combined two pictures taken from the same place, so that I could focus both the Moon and the branches and leaves of the maple tree in the same picture.

Primary rainbow

Kari Hassinen, Keski-Uudenmaan Altair

On Sunday, a fragment of a rainbow had already been seen earlier, but later in the evening, the main rainbow could still be seen in its entirety, as well as a side rainbow.

Primary rainbow

7.8.2022 at 18.00 - 18.15 - Tuusula (III)
Kari Hassinen, Keski-Uudenmaan Altair

While on a bike ride, I noticed a rainbow in the sky. Although only a small part of the curve was visible, the colors were strong as a counterbalance. I continued the rest of the run to my home, and I still had time to put the drone in the sky to take a couple of pictures of the arch.

Beautiful summer morning and halo decoration in the sky.

Several halo forms

Kari Hassinen, Keski-Uudenmaan Altair

Already in the morning and at noon, very faint halos were visible, but I did not photograph them. In the afternoon, after the association’s halo alarm on my cell phone, I set off in a slightly more spacious place to take a few recordings.

9.5.2022 at 10.15 - Tuusula (II)
Kari Hassinen, Keski-Uudenmaan Altair

Monday morning started like last week - watching the halos. At first, only the side sun was visible, which I didn’t take a picture of. A couple of hours later, a rather dim 22-degree ring and faint 22-degree arches above and below had formed in the sky. Upon closer examination and processing of the images (Figures 3 and 4), a horizon ring and a 46-degree ring were revealed.
