Partial solar eclipse

10.6.2021 at 13.55 - Kauhava (IV)
Jari Kankaanpää, Lakeuden Ursa

Partial eclipse. I was late twice during this session. At the beginning 5 minutes when I forgot myself over the tuna bread and in the middle of course I stopped at the camera on just as the passenger plane rushed over the sun disk. (It's nothing #! #). Otherwise, the people also prefer Finns.

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

Ina (Caldera D)

19.4.2021 at 21.07 - Kauhava (III)
Jari Kankaanpää, Lakeuden Ursa

In connection with a great observation previously published by Jerry Jantunen, I am posting a picture I took at the same time. The mystical Ina can be admired mainly from the windows of the moon ship, but the bonga drive makes you hunt it with a telescope as well. The lighting was good for seeing the subject, but the weather was otherwise restless. The high position of the moon at the time of observation helped a little.

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.

Hesiodus A

24.3.2021 at 22.40 - Kauhava (III)
Jari Kankaanpää, Lakeuden Ursa

On the south shore of Mare Nubium is the famous double-circle Hesiodus A. Apparently, the successive strikes of a collider broken into two parts have given birth to this special "double crater". the diameter is about 15km. The lighting was good, but the weather was not there for the observation of this rather small object.

Copernicus

22.3.2021 at 17.34 - Kauhava (IV)
Jari Kankaanpää, Lakeuden Ursa

Dawn on Copernicus. The first rays of the rising sun hit the eastern rampart of the crater. There is still icy darkness at the bottom. Three hours later, even the highest peaks of the western rampart pained in the light of the morning sun. Pictured in the middle is a slender flat Stadius and on the right Eratosthenes. Who is probably the peasant who first stands on that edge of Copernicus looking at the bottom of the crater, and when? Chesley Bonestell imagined the scene in the 50s in his painting. (Image found in Bonestell-Ley The Conquest of Space WSOY 1952). #Lunar100: 005

Apenniinit

22.3.2021 at 17.30 - Kauhava (IV)
Jari Kankaanpää, Lakeuden Ursa

Eratosthenes and the Apennines The location of the moon high in the afternoon sky allowed the use of 3x Barlow. There was a lot of material. https://lakeudenursa.fi/kuvitus/picture.php?/1127/category/4 #Lunar100: 040

Mare Nectaris

17.2.2021 at 16.47 - Kauhava (III)
Jari Kankaanpää, Lakeuden Ursa

The nectar sea has solidified into a basalt valley. On the left is the crater trio Theophilus at the top, Cyrillus and Catharina. The diameter of all is about 100km. The northern rampart of Fracastorius on the southern edge of Nectarkis has disappeared into the floods of the Nectarchite.

Grimaldi

2.12.2020 at 01.53 - Kauhava (III)
Jari Kankaanpää, Lakeuden Ursa

Grimald's pool in full moon shadless lighting conditions. The dark flooded area in the middle is about 100km in diameter. In good conditions, it appears as a dark spot on the left (west) edge of the full moon, even with the naked eye. The light ring indicates the approximate location of the inner curb. Its diameter is about 170km. https://lakeudenursa.fi/kuvitus/picture.php?/1114/category/4

Lacus Autumni

2.12.2020 at 00.40 - 00.45 - Kauhava (IV)
Jari Kankaanpää, Lakeuden Ursa

The lakes meander between the perimeter mountains of Mare Orientale. Lacus Autumni and Lacus Veris in the light of the full moon. https://lakeudenursa.fi/kuvitus/picture.php?/1120/category/4

Reiner gamma

2.12.2020 at 00.22 - Kauhava (III)
Jari Kankaanpää, Lakeuden Ursa

Reiner Gamma Mystical “Lunar Swirl” with Oceanus Procellarum. Mystical because its origin and birth process are still unclear. The powdery sugar-like light swirling patterns do not cast any shadows on the surrounding valley. Looks like the patterns are spray painted on the surface of the moon. Low-flying sonar has detected changes in the magnetic field in the area. Some theories assume that this anomaly affecting particle current movements in the solar wind interacts with lunar regolite dust. For millions of years, the dust has been forced by a magnetic field into now visible patterns. The cha...

NGC 2237

20.11.2020 at 02.46 - Kauhava (IV)
Jari Kankaanpää, Lakeuden Ursa

The hydrogen rose Rosette flies midnight into the winter southern sky stage. This huge emission nebula can be found in the unicorn constellation. The distance of the fog is about 5,000 light-years. In the middle of it is an open array of hot stars that have blown a bubble into the surrounding hydrogen vapor. The cloud itself is 130 light-years in diameter. It contains a wealth of interesting structures and star-bearing regions.

Telescopic comet ATLAS

10.11.2020 at 01.57 - Kauhava (III)
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.

Sun

8.11.2020 at 13.34 - Kauhava (III)
Jari Kankaanpää, Lakeuden Ursa

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.

Janssen

3.11.2020 at 23.42 - Kauhava (III)
Jari Kankaanpää, Lakeuden Ursa

Janssen is located in the southern highlands of the moon. At the bottom of the 190km diameter crater is a wide crack with side branches. In the picture, north is on the left.

Mars

28.10.2020 at 19.00 - 20.00 - Kauhava (IV)
Jari Kankaanpää, Lakeuden Ursa

During the observation break caused by the rainy season, I looked at the situation so far, what has accumulated. I compiled such a "preliminary map". From the Sinus Meridian area, the footage is weak. Hopefully a decent observation window would still open. (The date and time are the time the map was created). The findings are from August to October.

Mars

24.10.2020 at 01.51 - Kauhava (III)
Jari Kankaanpää, Lakeuden Ursa

Mare Erythraeum dominates the view. Niliacus Lacuskin shows up. Admittedly, it is more noticeable when the northern hemisphere is turned towards the ground. This 2020 opposition will mostly serve the landscapes of the southern hemisphere.

Mars

20.10.2020 at 01.40 - Kauhava (IV)
Jari Kankaanpää, Lakeuden Ursa

The wildest seeing variation throughout the opposition. From bad to excellent in just minutes. The soft and slow ripple of the atmosphere could stop abruptly for a moment and continue as a rapid vibration. Here is 15 percent of the 15,000 square set. I would use the definition of seeing good. Sometimes you have to try to manually pick up sharp squares and see what would be the end result.

Mars

17.10.2020 at 01.03 - Kauhava (IV)
Jari Kankaanpää, Lakeuden Ursa

"Interplanetary Smiley" Mars stares (Solis Lacus) at the ground, wondering at the opposition's enthusiasm for filming at Tellus. To say goodbye, it seems to strike the eye (MareSirenum).
