There have been halo phenomena caused by high clouds for many days and this morning was gorgeous when, in addition to the usual halo shapes, a 46 degree ring was also visible.

Pearl clouds

24.12.2017 at 14.00 - 14.30 - Oulu (III)
Sylvain Eckhardt

There were type I pearl clouds at and after sunset. I was dreaming that glowing pearl clouds would also be visible, but were not visible at that time (2 pm to 2:30 pm). Maybe there have been observations later?

Several halo forms

11.4.2017 at 20.10 - Oulu (II)
Sylvain Eckhardt

The halo phenomenon was almost all afternoon, but only in the evening did more halo forms (22 degree ring, sun pillar, side sun, 22 degree lateral arc)

Quiet aurora band

Sylvain Eckhardt

I decided to start filming repos apparently at just the wrong time, when the best steps seemed to happen earlier in the evening and after 2 p.m. at 23-0 there was sometimes an active or calm northern lights belt, after which it was quiet again (dim northern lights arc but). It got a little activated at about 1:30 but the play stayed quiet. The first picture was taken at 23:25 and the last at 1:30.

Several halo forms

I went to watch the evaporation fog caused by frost and melt water on the bank of the Oulu River and a good coincidence, at the same time there was a halo phenomenon caused by upper clouds (22 degree tire and less noticeable 22 degree overhanging arc) http://oulunvuodenajat.blogspot.fi/ https://www.facebook.com/Oulu- seasons-1834050886863108/

There were pearl clouds again (Type I pearl cloud) in the Oulu sky tonight. The second picture also includes Venus and the moon. I don't always have time to leave observations in the sky, but they can always be found on my blog: http://oulunvuodenajat.blogspot.fi/

Pearl clouds

Sylvain Eckhardt

There were pretty bright pearl clouds during and after sunset, but they weren’t colorful at all. Sure, I’m not 100% sure if there were pearl clouds. I don't always have time to leave observations in the sky, but they can always be found on my blog: http://oulunvuodenajat.blogspot.fi/

Tonight there will be ice fog in Oulu at a temperature of -17 degrees and artificial light pillars can be spotted all over the city.

Several halo forms

11.11.2016 at 13.00 - Oulu (II)
Sylvain Eckhardt

After a night and morning snowfall, the sky began to clear and there were ice crystals in the air that caused this halo, which did not last very long as the sun quickly went into the cloud. At the same time, there were great Kelvin-Helmotzes. A sun column and the lower parts of the 22-degree tire were noticeable.

Sumukaari

The fog was weakly visible over the morning in Valkiaisjärvi, Oulu. The sun was already quite high, in the past it might have been more spectacular?

Active aurora band

5.9.2016 at 23.30 - 01.40 - Oulu (III)
Sylvain Eckhardt

Again came a sudden departure to the scene, this time Nallikari beach. The packing and the journey took place and afterwards you will notice that the best moment has already passed, but there was a spectacular active northern lights belt in the sky when I arrived. The first and second pictures I took around 11:35 p.m. and 11:40 p.m. were almost over. After that there was a very dim northern light gauze. It started to happen again at about half past two (the last two pictures), but it didn’t last very long and otherwise more clouds started to come all the time.

Dim northern lights were on offer tonight. There was at times but a northern lights gauze that activated as an active belt, but were dim all the time.

Half-sky auroras

2.9.2016 at 00.30 - Oulu (IV)
Sylvain Eckhardt

The evening had become signs that northern lights had been on offer. At midnight I hadn’t noticed anything special and a little later started to see a dim arc. I went to photograph the yard when there were other responsibilities and unfortunately couldn’t go to a better place. At first there were dim but sometimes really fast fires. Later, the two countries began to happen and more than half-sky northern lights. The brightest northern lights remained annoyingly unreported at about three o'clock. Apparently 4-5 times was the worst geomagnetic interference, would it have been worth monitorin...
