Moon

23.9.2022 at 04.04 - Kokemäki (III)
Jari Kuula, Porin Karhunvartijat

23.09.22, 04:04. The autumn equinox, the idea was to photograph the crescent of the Moon with a mobile phone at that very moment. On the side of the neighboring county, in Kokemäki Kuurola, I knew there was a dark open field from where it could be seen. The weather did not favor my venture, and the Lion and the Moon rose from the only open searchlight. However, the result celebrates the spiritual point. event. Happy Autumnal Equinox!

Moon

20.8.2022 at 02.45 - Harjavalta (IV)
Jari Kuula, Porin Karhunvartijat

Mobile phone photography in a tropical night (+20 degrees). The Moon and Mars formed a nice triangle with the Pleiades. PKV.'s heritage pipe, 170mm maksutov made by Sal, was digitalized by our tour guide. Seppo presented his device at the Lahti star days in 1976. Otherwise, the observation night was spent remembering legends. I matched the recording of the moon to its first vertical crossing. Parrot marks for everyone who remembers that semicircle, at right angles to the meridian. The astronomy enthusiast's book has a star map with overlays, and that too explained. At the end of the 19...

Julius Caesar

7.5.2022 at 22.45 - 23.45 - Harjavalta (IV)
Jari Kuula, Porin Karhunvartijat

The company draws Julius Caesar in the morning light. A year ago, I drew JC in an earlier light. This nectar crater is about 85 km in diameter. It no longer has its western and northern dominions, even those plowed by the Imbrium throwing 3.85 billion years ago. The infiltration basin is about 1100 km northwest. The southern bottom of the JC is 800 m higher than the north, again due to the Embrian dump. The dark, northern layer of lava has apparently risen from the crack of the bottom, as there does not appear to be a canal or fairway to the east, to Mare Tranquillitas. Seeing was great, with ...

Moon

15.4.2022 at 23.23 - Harjavalta (III)
Jari Kuula, Porin Karhunvartijat

Not really an observation, but an implementation of an idea. T + A 3/2022 p.64 Jeff Graphy presents the projection of the Moon, and the image inspires us to think of the same system with a small tube. I would make the scaffold stand out of paff and grill sticks, and the reflective surface itself is translucent paper, so the image is viewed opposite the eyepiece. Nearly a full moon was photographed admirably despite the stray light, and a brighter telescope with a larger aperture would work better. In star shows and teaching situations, one could use when several can watch the same, live image.

Sun

29.3.2022 at 14.00 - Harjavalta (III)
Jari Kuula, Porin Karhunvartijat

The sun showed up, so the refractor in the yard cooled down. Guys have said that spot activity is on the rise, finally! Wanha Evostar works well with Baader's Herschel wedge, filming on a mobile phone was a problem. The monk's hood trick recommended by Heikkilä Risto works here too. I photographed the spectrum through a DIY gadget (cardboard, razor blade. DVD), the lines in the original image stood out. The green color is created by the wedge filters.

Mons La Hire - Carlini

12.3.2022 at 19.00 - 19.50 - Harjavalta (IV)
Jari Kuula, Porin Karhunvartijat

The company draws L98 on Charles Wood’s Lunar 100 list. Embarrassing conditions for observation truncated the results mainly to the visible lava flows between Carlin and McDonald. The thickness of the floor is about 35 m, so the so-called shadow magnification works great for items like this. Stratus and his friends hindered the drawing, although they sometimes made pretty rings around the moon.

Promontorium Heraclides

11.2.2022 at 21.18 - Harjavalta (IV)
Jari Kuula, Porin Karhunvartijat

Hakala Raimo's observation inspired me to examine my mobile rapids from the Moon in the evening of 11.02. Prom. Heraclides was illuminated with the environment overshadowed. In Jean-Dominique Cassini’s monthly map from 1679, the promontory is clearly depicted as a female figure, and I don’t remember seeing the maiden as tender as that night, the picture really doesn’t do her justice! Cassini had married Genevieve de Laistre in 1673, and some scholars consider it possible that Moon Maiden is an astronomer in recognition of his wife's love.

Mons Argaeus

22.1.2022 at 01.50 - 02.40 - Harjavalta (IV)
Jari Kuula, Porin Karhunvartijat

The company draws Mons Argaeus in the evening light. The night was unconsciously humid, even though the thermometer showed -11 degrees, within an hour the drawing board went all the way to the skipper! Mount Argaeusv is on the eastern edge of the strait between the Serenitatis and Tranquillitatis plains. It is about 65 km long and about 2600 m high at its northwestern end. The array was named Webb in 1859. Argaeus is an ancient name for a volcano in present-day Turkey. The ancient geographer Strabo (64 BC-24 BC) says: The mountain is in Cappadocia, and at its foot is the city of Mazaca. The to...

Mare Orientale

26.12.2021 at 01.45 - 02.20 - Harjavalta (IV)
Jari Kuula, Porin Karhunvartijat

The company draws Mare Orientale at a time of favorable librarianship. Small, gusty, -18 degrees Celsius. The viewing pleasure dropped relative to the temperature cube, resulting in the fastest drawing of the winter! The moon was low (about 32 degrees) and there was something awkward in the air, not good weather. Nicely, however, the eastern sea was visible with its small lakes, just as if the far end of the sea had also separated. The Orientale Basin has broken the old craters of the region at birth, with young Byrgius A trying to clear it by extending its rays all the way to the sea. The IAU...

Aristarchus

16.12.2021 at 22.30 - 23.25 - Harjavalta (IV)
Jari Kuula, Porin Karhunvartijat

The company draws Aristarchus with its plateaus. Seeing was not as good as the top looked, and the terminator was perhaps already too far away. A has a diameter of 40 km and an age of about 450 million. years. It is the brightest crater of the Moon, it stands out well in the ground. The highlands stand out in Wanha's eyes as brick red in this light as well. On the radar, it is a bad reflector, meaning that there are no fist-sized and bigger boulders. Apparently it is covered with a few meters of volcanic ash, containing ferrous glass. The dark mantle of the plateau is older than the surrou...

Cleomedes

21.11.2021 at 22.30 - 23.30 - Harjavalta (IV)
Jari Kuula, Porin Karhunvartijat

The company draws Cleomedes in the evening light. The observation weather was really good by November! The bottom of the C is clearly convex, and the Tralles that hit the northwest edge have pushed the masses to the bottom of the big crater. The three-pointed central mountain of C rises to a height of almost a kilometer. Rima Cleomedes did not stand out until it was drawn, instead Rima Burckhardt stood out in the same direction. The latter begins at the southern edge of Geminus. Burckhardt is characterized by its ears, with two older craters centrally below it.

Deslandres

28.10.2021 at 02.55 - 03.45 - Harjavalta (IV)
Jari Kuula, Porin Karhunvartijat

The company draws Delandres and a couple of details from the surrounding area. Lexell was born on the southern edge of D, 64 km in diameter. This lighting is distinguished by a shallow canal starting from the break point (northeast) of the L edge rampart and extending to the bright spot of Cassini. This northwesterly shape is shallow, 10 km wide and 110 km long. The canal in the upland area poses an interesting problem in terms of its mode of origin. SJ O´Meara gave the name Charon´s Canal because D was sometimes called Hell Plain. The central mountain of Regiomontanus was another detail in th...

Atlas

24.10.2021 at 00.35 - 01.22 - Harjavalta (IV)
Jari Kuula, Porin Karhunvartijat

The attempt to draw Atlas and Hercules in the evening light, perhaps too early in the evening, the shadows were short. The weather was good, and the Moon was high, so the rills of Atlas stood out every now and then. The Atlas is an early-crimean crater, with a thick throwing mantle (Glacis) around it, except in the northwest, where Glacis sinks in the direction of Atlas E. Teemu Öhman recalled that TG Elger (1838-1897) launched the word Glacis defining: outer slope of a ring-plain. Hercules is eratosthenes, about 68 km in diameter. In the sonar images, Hercules E stands out as oval because it ...

Montes Caucasus

28.9.2021 at 03.10 - 04.00 - Harjavalta (IV)
Jari Kuula, Porin Karhunvartijat

The company draws the Caucasus Mountains in its evening light. Calippus C has lost its western edge, but the eastern edge, especially its southern part, rises to a height of 5 km. Montes Caucasus is said to be an Imbrium throw, but the concentric alignments don't really fit !? A cell phone rap at 3:49 a.m. shows a low ridge heading northeast from Theaetus. This shallow form has a width of about 25 km and a length of about 100 km. The ridge did not appear in the drawing, but the shoreline is also in the shade.

Fracastorius

26.9.2021 at 01.10 - 01.55 - Harjavalta (IV)
Jari Kuula, Porin Karhunvartijat

The company draws Fracastorius in late night lighting. It was formed on a 400 km diameter ring of the Nectaris basin, and tilted towards the sea due to the depression of lava. In a better picture and better lighting, an east-west slope stands out in the middle of the crater. On the north side of the channel, the lava is darker, and less cratered than in the south. The Fracastorius, more than 120 km in diameter, is No. 21 on the Lunar100 catalog.

Rima Hadley

20.4.2021 at 22.30 - 23.25 - Harjavalta (IV)
Jari Kuula, Porin Karhunvartijat

The company draws Rima Hadley. We were right on the limits of my unhappy vision. The river was caused by a lava flowing from an eruption called Bela in a direction northeast, and more than 80 km long. The red dot in the drawing indicates the generous landing site of Apollo 15. Rille makes a tight bend at the Mons Hadley Delta, and I remember in a mooncast in July 1971 that Heimo Tauriainen used the name Elbow Spider.

Ptolemaeus

19.4.2021 at 23.05 - Harjavalta (IV)
Jari Kuula, Porin Karhunvartijat

The last few days have been moonlit quality time, now threatened by a long period of cloud cover. Prior to its first quarter, the Moon has been high as it did in the spring, when the typical poor season of seeing does not hurt. I followed e.g. Ptolemaeus sunrise, the first rays of the crater's convex base to the humps of the dawn to record on a cell phone binocular from the left horn. The overexposure in Figure 2 briskly to verify the phenomenon. Another phenomenon that is also visible in mobile phone flippers: big craters are hexagonal !?

Julius Caesar

18.4.2021 at 21.45 - 22.40 - Harjavalta (IV)
Jari Kuula, Porin Karhunvartijat

The company draws the Julius Caesar crater. The shape is about 85km in diameter, and has experienced the destructive power of the throws of the Imbrium collision. The southern bottom area is 800m higher than the north, probably precisely because of the slopes of the Imbrium basin, and the north is darker apparently due to lava eruptions. Riccioli named a crater for J. C because of his calendar reform. Sosigenes, who assisted JC, also got its name from the neighborhood. Sosigeneen was assassinated by Octavian in a declaration of war to Egypt in 31 BC.

Promontorium Taenarium

21.3.2021 at 21.00 - 22.00 - Harjavalta (IV)
Jari Kuula, Porin Karhunvartijat

The company draws a promontory in the morning light. Taenarium is the name given by Hevelius, though John meant a peninsula a little to the west. He used to use the legendary names of the place of the Earth in his nomenclature of the Moon, with this Hevelius remembered the Tenarium (now Cape Matapan). According to legend, the southernmost peninsula of the Peloponnese has a cave from which Hercules went to pick up Cerberus. The Taenarium of the Moon is a tributary of the Imbrian Throw, and forms part of the rampart of the Ancient Thebit crater in the north (the Straight Ramp crosses this crater...

Moon

16.3.2021 at 20.00 - Harjavalta (IV)
Jari Kuula, Porin Karhunvartijat

As I watched the crescent moon on Tuesday night, the veteran's mind was warmed especially by the two mountain peaks twinkling around the South Pole, they received the first light of the Sun on this lunar cycle! Placard picture, ningo raumlaise sanova.
