Key to Images in this Issue 106

I hope that this issue finds you and your loved ones in good health in these uncertain times. In this issue of The Lunar Observer, Jerry Hubbell leads us on a tour of the Lunar 100, starting with the first 10 lunar tar-gets. Response to this has been incredible! In the Recent Topographic Studies, several images of these first 10 lunar targets are highlighted. Thanks so much for each who submitted observations. Also, Robert H. Hayes, Jr. investigates the region of Cassini C and E, Alberto Anunziato and Francisco Cardinalli have tours of the Bullialdus region and the Scheele Arc, Rik Hill, Howard Eskildsen and David Teske guide the reader on lunar expeditions through the telescope. As always, Tony Cook leads the Lunar Geologic Change Program with his in-depth research.

Wishing each all the best in these times.

Anthony Cook comenta una observación de Sergio Babino de Aristarchus para compararla con reporte de FLT de 1989:

Figure 6. Aristarchus orientated with north towards the top. (Left) An image taken by Tony Cook from 1989 Oct 13 from video at the tail end of the LTP – reprocessed by Thierry Speth. (Center) A sketch made by Tony Cook from the video recording at the tail end of the LTP on 1989 Oct 13 with the location of the bright blob outside the east rim, and the location of the “Ghost Crater” effect seen earlier during the LTP.
