Part of the south eastern edge of the visible part of the Moon. We see a
group of big craters around Hagecius. We orientate ourselves using the
crater Hommel. It has a number of smaller craters across the rim of the
crater forming a striking massif.

Discovered the comet Biela.
) (Dept: 3,100m) (54.9°S, 51.3°E) The rim of this crater is
overlaid by a pair of craters: Biela C across the northeast rim and Biela

) (Dept: 3,200m) (70.4°S, 54.7°E) A large crater that lies within the
outer walls, so that it looks like a double-walled formation.
Sir David Gill
(1843 - 1914) Scottish astronomer, compiler of a star catalogue.
) (Dept: 3,930m) (63.79° S, 75.92° E° ) On June 11, 2009, the Japanese
lunar orbiter spacecraft was
deliberately crashed into the surface of the Moon to the southeast of
Gill. The impact site was at selenographic coordinates 65.5 S, 80.4 E. The
flash from the impact was successfully observed from Mount Abu Observatory
in Gurushikar, India. and by the Anglo-Australian Telescope.
