Mare Crisium - 21.11.2021 at 21.10 - 21.11.2021 at 21.30 Vantaa, Pähkinärinne Observation number 102450

Visibility IV / V

Paula Wirtanen, Ursa (Helsinki)

Mare Crisium showed up nicely with the terminator. Thanks to good seeing, I was able to view this at 250x magnification. The edges of Mare also stood out very nicely from the terminator side.

To the north of the crater Mare Crisium is Cleomedes.

Figure 1 shows an outline of the area, Figure 2 a photograph of the area.

#Lunar100: 010

Joo, tämä on hieno Kuun vaihe. Siinä on kaksi lyhyttä "kultaista kädensijaa". Hauskan näköinen on myös tuo neljän ison kraatterin jono terminaattorilla! Vähän kuin paidan napit rivissä.

Kyllä, hienon näköinen Kuu oli eilen. Irroitin tuon "paidannappikuvan" omaksi havainnolseen ja käsittelin sitä uudelleen pinoamalla.
