I always learn so much putting The Lunar Observer together. In this issue, there are insightful articles about the lunar terrain by Alberto Anunziato, Rik Hill, Howard Eskildsen and David Teske. Howard again analyzes his images and finds some new (to him and I) concentric craters. What is hiding in your observations waiting to be discovered? As always, Tony Cook provides a thorough investigation of Lunar Geologic Change.

En “Lunar topographical studies” se mencionan las siguientes observaciones:
