![]() Its satellite craters V (24 km), A (29 km) and H (43 km) are all first time observations for me. Of course Urbain Le Verrier was the man who eventually discovered the planet in 1846.įraunhofer (57 km) is another crater I should have found before. Having observed many times, I am a little bit embarrassed it has taken this long for me to finally see himself on the Moon. But I am particularly pleased to have now observed these 3 craters as they are named after John Couch Adams (1819-1892) who made the calculations for finding the planet Neptune in the Solar System. Adrien Legendre (1752-1833) was a French mathematician.Īdams (66 km) + B (28 km) + D (42 km) are new to me. Its rim is extremely difficult to see - especially as it is near the limb. Legendre (78 km) is a very shallow crater. Mare Crisium was most certainly closer to the lunar limb on this occasion because of lunar libration.Ĭleomedes (126 km), A (12 km), Tralles (36 km), Debes (31 km), A (33 km), B (19 km), Macrobius (64 km), Tisserand (36 km), the triple crater Burckhardt, (57 km), E (39 km), F (43 km), Langrenus (132 km) with its 2 central peaks, Petavius (177 km) + Rimae Petavius (80 km), Wrottesley (57 km), Vallis Palitzsch (110 km), Hase (83 km), A (15 km), Palitzsch (41 km) and Furnerius (125 km), B (22 km).Įach of these I have observed before over the years.īut the features I have not seen before are these: I shall start with the ones I have seen before.Īs Mare Crisium was clearly visible, I thought I ought to ignore the terminator for a change. I use Antonin Rukl's Atlas of the Moon at all times. Some of these lunar features I have observed before but quite a few I have not. The highest magnification I used was 112X - as the seeing was not great. So from here on, our sunsets will be getting a little bit earlier after each night.įor the record, the magnitude of Luna was -8 an illumination of 14% an angular diameter of 32' its distance = 373,181 kms from Earth. Sunset at this time of year in Dublin, Ireland occurs at the latest possible time of 21.57 Irish Local Summer Time. ![]() On Wednesday 24th June 2020 I observed a 3.5 day old crescent Moon in the western sky before and after sunset for over 1 hour EDITOR: Lubiniezky and surroundings can be found on Map 53 of Rukl’s Atlas of the Moon.As some of you know, I own a William Optics 158 mm F/7 apochromatic refractor. There was also some chaotic terrain to the northwest that I did not draw. The area around Lubiniezky sigma also looked lighter than the area around Lubiniezky in general the mare material may not have reached there. The Lunar Quadrant Map shows Lubiniezky sigma to the north this may refer to an xshaped elevation that I drew. The crisp crater to the north is Lubiniezky D, and Lubiniezky beta is the largest of several peaks to the south and west. Otherwise the rims of this crater appeared to be fairly low, but there was an isolated strip of light on the east rim that may indicate some terracing. A similar feature may be on the north rim. The highest point on the rim appears to be a peak on the west rim that cast a substantial triangular shadow and also had a a ridge angling outward. There are gaps in the south rim, and the interior is smooth and featureless. This crater is in northwestern Mare Nubium, and has obviously been flooded by that mare.
