The double crater Boussingault in the eastern part of the South Pole is a good fixed point for orienteering in the area. It has a diameter of 131 kilometers. At the bottom of Helmholz, to the left of Boussingault, is a straight ridge like the hand of a bell. Thanks to the ligation, the re-embankment of the Hale Crater behind Boussingault can be seen, but the bottom is not. In the picture, the south is at the top. A strong wind disturbed the otherwise good weather.

I was still visually inspecting the AR 2993 & 2994 group in the evening. The sun was already low, but the views were interesting, so I took a few pictures.

Pythagoras is located near the north pole of the moon. It has distinctive terrace-like embankments such as Tyko and Copernicus. The diameter of the crater is 130 km. The central mountains cast long shadows through the bottom of the crater all the way to the curb. The philosopher and mathematician Pythagoras (580-500 BC) "shaped" a flat earth into a sphere. (No one has to worry about falling over the edge anymore;)

This massive crease is in the footsteps of the birth of Mare Orientale. In the background is a similar formation per Inghirami crater. The terrain of the area is very complex, picking up a bit like the surface of Ganymedes in the moon of Jupiter. (This can be examined in more detail in the LROC sonar images). In the picture, the south is at the top.

Gassendi, located on the northern edge of Mare Humorum, is a destination rich in detail. Now the lighting was just right and good for exploring this 110km diameter crater. At the bottom is the intricate crack network of the Rimae Gassend. In the picture, the south is at the top

A few picks from six sessions from March 13th to March 18th. Pretty bright but restless weather. Sinus Iridium and Plato were recorded in fairly good conditions. Others avoidable.

Moon surface feature

Jari Kankaanpää, Lakeuden Ursa

Rima Hyginus This 220km long Rilli is located on the southern edge of Mare Vaporum. In the middle of the ridge is the Caldera - about 9km in diameter. Probably a volcanic formation, as it does not show edging ramparts that would rise above the surrounding plateau. A chain of at least 12 craters is visible in the gorge branching from the caldera to the northwest (upper left). The chain is probably the result of a collapsed lava tunnel, or they are smaller discharge openings.

Hausen Hausen, located on the edge of the west-southwestern vibration zone, appears intermittently disappearing from time to time on the dark side. The diameter of the crater is 167 km. In the middle of the stepped curbs there is a complex cluster of peaks. The picture shows a gorge that divides the cluster into two parts. It is interesting to explore the area using a 3-D globe / QuickMap compiled from LROC sonar data. Especially with the Fly around function, you can adjust the flight altitude and marvel at the complex structures of the mountain slopes, such as the giant cliffs that have rolle...

Bailly

15.1.2022 at 20.54 - Kauhava (IV)
Jari Kankaanpää, Lakeuden Ursa

Dawn with Bailly on Saturday night. Near the south pole of the moon is the western edge of one of the largest craters on the visible side. The 303-mile Bailly is an old but handsome revelation when the lighting is appropriate. In the picture, the sunlight has already reached the peaks of the western rampart while the bottom is still in the darkness of the night. https://lakeudenursa.fi/kuvitus/upload/2022/01/16/20220116222129-844f5adc.jpg

Jari Kankaanpää, Lakeuden Ursa

The moon was high in the southern sky and the weather was better than usual. As the sun set on the eastern edge, Langrenus 130km (left) and Petavius 177km (right) offered dramatically rugged views and plenty of detail. r https://lakeudenursa.fi/kuvitus/upload/2021/11/22/20211122162724-7c6baee8.jpg

Partial solar eclipse

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

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
