Walter & Deslandres

20.4.2021 at 21.18 - 21.22 - Kauhava (IV)
Jari Kankaanpää, Lakeuden Ursa

When I spot that Walter-Deslandres area, my focus is often on that fracture on the western edge of Walter. It appears as if part of the curb had detached from point A and moved to its current position at point B. Catchment area C is elevated from its surroundings and it would seem as if there were indications of an event at the bottom of Deslandres in area D as well. Probably it is just a remnant of the edge wall of the crater covered in Desavares lava. https://lakeudenursa.fi/kuvitus/picture.php?/1130/category/4

Walter

19.4.2021 at 20.18 - 20.20 - Kauhava (IV)
Jari Kankaanpää, Lakeuden Ursa

Rough mood with a terminator. Occasional calm moments provide small details to be seen such as craters less than a kilometer in size at the bottom of Stöfler. (Bottom left). The shape of Walter’s triangular base is accentuated in this shady lighting. (Top right). Walter has a diameter of 132 X 140km. In the picture, north is on the right.

vdB 142

Jari Kankaanpää, Lakeuden Ursa

Inside the IC 1396 A of Cepheus, a dark mist vlB 142 is found. Due to the shape of its tip, its nickname is "Elephant's Tip." The length of the toad is more than that of all African and Indian elephants suffer a total. The length of the fog is about 20 light-years and the distance n, 3,000 light-years.

Transit of mercury

9.5.2016 at 16.04 - Kauhava (IV)
Jari Kankaanpää, Lakeuden Ursa

Like a tiny iron pepper over a cosmic orange. Mercury slid slowly in a completely cloudless sky over the sun. Only the initial 45 minutes and the remaining 30 minutes remained unrecorded. The material accumulated in a gig trade to be collected in a rainy-day cart.

"May Day fan and serpentine." C 2012 K1 and background galaxies M 51 still grabbed from the lightening sky.

Telescopic comet ATLAS

Jari Kankaanpää, Lakeuden Ursa

Squirts under Orion's belt. A little silly cropping, but let's act as a reference if someone wants to check where the comet is.

Ar 2674 & Ar 2673 A particle storm coming in the coming days. Northern Lights Graphs get ready.

Jari Kankaanpää, Lakeuden Ursa

As the starry sky brightens, you have to move to brighter objects. Our home star is in an unusually calm mood. The sky partially opened on Saturday night and I took a couple of sets.

Sun

20.5.2020 at 17.24 - 17.35 - Kauhava (III)
Jari Kankaanpää, Lakeuden Ursa

A small increase in activity is observed on the surface of the sun. Strong winds interfere with daytime observations of the inner planets, so I decided to take a look at what is happening on the surface of the sun. Pair discharge area on the disk, one of which in the foreground. Conventional protu on the edges.

Monday monster. This ghostly transformation came to be followed for hours.

Mr. Helios had set up one in his backyard volleyball net. Didn't really stand the heat, when it looked about ragged.

AR2765 I first tried to photograph a comma cluster with mylar film and visible light. The marvelous difficulty of focusing in my time I assumed was due to thick pollen and intense vibration. I switched channels to H-alpha frequencies, and immediately got better views.

Shortsiastronomy, i.e. the observation of minds in the middle of a clear day. Rain with clouds and too light skies do not yet allow a comet to be observed from this southern Ostrobothnia.

AR2767. Is there a herald of a new period of commas. With its magnetic field very much twists the sun on an otherwise flat surface.

On the surface of the sun, a small increase in activity. Friday superprote went just past us, but luckily the Sky Guard is great documents about what happened. EDIT: Figure 2: AR2768 and AR 2769 The "double porridge eye" of Cycle 25 roars with interesting twists on the surface of our home star. Here and there a few steam prototype loops. This is a 2x Barlow scooped detail of that I posted earlier from the full disc view. The image has stretched levels and contrast adjustments to emphasize details.

Less frequently, that sun in November is described. There are many great shots of this Father's Day light phenomenon in the Sky Watch. Here, the sequence extends the active region in AR 2781 h-alpha light. Just before this picture was taken, a distant flock of geese flew in front of the sun's disk. I was just about to switch Barlow to the camera when I happened to spot the geese. I got a few seconds of the flock from the flight path at the comma group over the puck to the right. You have to get tired of animation sometimes about that lucky coincidence of Father’s Day.
