Windy. Cloud cover increased during the session. Good viewing until the clouds completely covered the Moon. Sucker holes thereafter. The sucker holes allowed for brief viewing of the Moon. One view (from Sinus Iridum to the Moon’s north limb) was only seen for about 30 seconds; this allowed for a rather hurried sketch.

Schikard was near the terminus. Its westernrim had shadowing and there was a crater at its southern end.

Sirsalis and Sirsalis A: the left side was more shaded than the right in the FOV and ‘darker’ than the surrounding terrain.

Identified Cavalerius, Hevelius and Lohrmann north of Grimaldi. Luna 9 landing NE of Cavalerius on Oceanus Procellarum.




Identified Foucault and Harpalus in Mare Frigoris north of the Montes Jura. Also identified Babbage north of Frigoris with a crater on its floor (centred?).  The latter was the largest of the 3 and was near the limb.

Maria: Crisium, Frigoris, Humorum, Imbrium, Nectaris, Nubium, Serenitatis, Tranquilitatis, Vaporum.

Sinus: Iridum, Roris

Craters: Grimaldi, Hevelius, Schikard

Found Craters not on the list: Babbage, Cavalerius, Foucault, Harpalus, Lohrmann, Sirsalis & Sirsalis A
