Abstract

Gutenberg (45 miles) is a formation that at first glance looks like an old fashioned keyhole. The western walls rise over a mile above the floor. Part of the eastern rim is destroyed by a later impact and the southern wall is also missing from the impact that makes up the bottom of the keyhole. There are a number of small peaks on the floor. When observing this area with 6 or more inches of aperture you will see a rill running from the east to the northwest. There are also rills outside this crater to the northeast. If this crater is visible at an observation, show it to your viewers for its unusual shape. It will be well placed for observation 5 days after new Moon.

Goclenius (33 miles) has rather low walls that are less than a mile above the floor. Under good seeing conditions my 6 inch refractor reveals a rill that crosses the floor from the southeast to the northwest. Most of the rills around Guttenberg and Goclenius run in this direction.
