Rare halos

21.1.2023 at 11.47 - 12.30 - Lahti (IV)
Teemu Hämäläinen, Lahden Ursa

Last Saturday, several different halos were visible in the fairly dense ice fog, the brightest of which was the 22 overhead arc. However, the most special was a very diffuse colorless arc, which was quite sharply defined, roughly estimated at a distance of about 80 degrees from the sun. The highest point of the arch reached to the sky. I don't know if the arc is the right term for that halo, because it seemed more like the border of the ice crystals flickering, so that you could see crystals on the side of the sun and significantly less immediately outside the arc.

Clearly visible night shining clouds

23.7.2022 at 00.14 - Lahti (III)
Teemu Hämäläinen, Lahden Ursa

Nice night clouds were visible around midnight. At best, wisps of clouds reached the sky. An interesting detail was the small wave area.

7 Iris

9.3.2022 at 20.00 - Lahti (II)
Teemu Hämäläinen, Lahden Ursa

Ursa's Stars Yearbook had reported the appearance of the asteroid Iris during early spring. I followed the movement of the song four evenings at the turn of February and March. The composite image is composed of four stacked images, each with approximately one minute of exposure. At the last observation on 9.3, the asteroid's brightness had dimmed somewhat, and the rising moon hampered the observation with its brightness. The bright stars in the pictures are 45 and 51Geminorum.

Sun

Teemu Hämäläinen, Lahden Ursa

The sun is still so low that you had to search for a place to shoot so that one of the tree tops would not hurt in front of the sun.

Moon

10.2.2022 at 21.45 - Lahti (III)
Teemu Hämäläinen, Lahden Ursa

The moon shone handsomely from the almost cloudless sky on Thursday night.

Moon

Teemu Hämäläinen, Lahden Ursa

A rising moon photographed through a cloud of gauze.

ISS

7.1.2018 at 07.02 - Lahti (III)
Teemu Hämäläinen, Lahden Ursa

I noticed from the Heavens-Above app that the ISS would be going very close to Mars and Jupiter on a Sunday morning. The weather forecast promised clear weather so I had to try to describe it.

Rare halos

5.1.2016 at 12.07 - Lahti (IV)
Teemu Hämäläinen, Lahden Ursa

Very bright side suns were visible during the day. The crystal rained fairly evenly over a wide area, but at its best the halos were around noon. Later in the afternoon, a very dense fog of ice flew from the west where no halos were visible. The 44 side suns appeared as very dim reddish vertical streaks. It was about -18 from the frost.

Sun

29.12.2015 at 14.41 - 15.12 - Hollola (III)
Teemu Hämäläinen, Lahden Ursa

A series of photos taken at sunset in a hurry. Throughout the half-hour, the dart was hitting cones in the adjacent tree, always occasionally searching for more.

Moon

14.12.2015 at 17.48 - Lahti (III)
Teemu Hämäläinen, Lahden Ursa

The moon was beautifully visible above the forest.

Venus, Jupiter, Mars ja Regulus

28.9.2015 at 06.33 - Lahti (II)
Teemu Hämäläinen, Lahden Ursa

The moon was not visible, but there were plenty of planets on offer. Admittedly, they were only visible for a moment between the clouds.

Eclipse was overcast

28.9.2015 at 05.47 - Lahti
Teemu Hämäläinen, Lahden Ursa

Before four the moon had appeared a few times, but after that the western sky was blocked. There were several cloudless areas, but none of them walked close enough to the horizon.

Rare halos

9.9.2015 at 14.31 - 15.00 - Lahti (IV)
Teemu Hämäläinen, Lahden Ursa

It came as a surprise when I happened to look at the sky. Attention was first drawn to the bright top-side and left-hand side sun. Parry was well visible. The halos on the side of the sun slowly faded, but 120saur brightened for a moment.

Quiet aurora arc

18.8.2015 at 00.57 - Lahti (II)
Teemu Hämäläinen, Lahden Ursa

While at the tower, we had to peek north where a faint arch happened to appear.

Moon

2.7.2015 at 22.57 - Hollola (III)
Teemu Hämäläinen, Lahden Ursa

The first full moon of July.

Several halo forms

29.6.2015 at 18.31 - Hollola (II)
Teemu Hämäläinen, Lahden Ursa

For a moment, several halos appeared in the upper clouds, though not very bright. The side sun was also visible.

One halo form

27.6.2015 at 16.14 - Hollola (I)
Teemu Hämäläinen, Lahden Ursa

As the clouds of deafness passed, a 22-degree ring was visible in the sky.

Venus

21.6.2015 at 18.17 - Lahti (II)
Teemu Hämäläinen, Lahden Ursa

The air brightened towards the evening and the moon appeared in the southern sky. Based on the previous evening, I was able to estimate the position of Venus in the sky relative to the moon, which made the search much easier. Venus was surprisingly bright when it happened to be seen.

A bright piece of horizon ring caught my attention.

Several halo forms

Teemu Hämäläinen, Lahden Ursa

As the upper clouds moved in the sky, a few halos were visible.
