Hoping all is well with each reader of the current issue of The Lunar Observer. As always, The Lunar Observer contains a number of interesting articles. Alberto Anunziato leads us on a tour of wrinkle ridges near Bessel and the ghost crater around the oddly shaped crater Torricelli. Rik Hill describes the roughed southern highlands with ACraters

and also explores sunrise over the Jura Mountains. David Teske discusses the very easily visible Gyldén Valley. Jerry Hubbell has led us over the past 20 months on the Focus-On series of the Lunar 100. The Lunar 100 was developed by Charles Wood as a tool to get a more in-depth knowledge of our nearest neighbor. This month concludes this series, with lunar targets 91-100. This contains some very easy to find objects like the Procellarum

Basin and the previously mentioned Gyldén Valley, and some notoriously challenging targets like the swirls in Mare Marginis and Ina. Alberto Anunziato leads us through these lunar targets, and is happy to report that ALPO observers found each of these targets. Great work! As has been discussed in the past, Jerry Hubbell has moved on to coordinate the ALPO Exo-Planets Section. We greatly appreciate all that he has done for the ALPO Lunar Section. His

Focus-On Lunar 1-100 has been very popular. Alberto Anunziato now is in charge of the Focus-On articles. Please note that two new topics have been selected, with Mare Crisium the topic for the January 2022 issue. We look forward to your work on Mare Crisium.

Many thanks to all who contributed to this issue of The Lunar Observer. There were 22 observers who contributed 102 lunar observations from 13 countries.

Clear skies,

David Teske

En este número se cerró la serie de artículos en la Sección “Focus On” sobre el listado Lunar 100. Para contribuir a este esfuerzo lanzamos el Programa Lunar 100 que fue un verdadero éxito, pudiéndose observar los 100 accidentes incluidos. En el número 21 de “El Mensajero de la Luna” seleccionamos 1 imagen por cada accidente del listado, se puede descargar de aquí:

https://drive.google.com/file/d/1wGbT31RcqFKds6JM0DGKhbME2tnGLaiA/view

Periódicamente vamos publicando las imágenes de este programa (y lanzamos números especiales de “El Mensajero de la Luna”).

En octubre se publicaron en “The Lunar Observer” los accidentes selenográficos incluidos en los números 91 a 100 (que publicaremos en el número especial 22 de “El Mensajero de la Luna”).

Se eligieron las siguientes imágenes para ilustrar la Sección (además de las incluidas en la Sección Focus On Lunar 100

Wishing each of you a joyous and safe Holiday Season! I hope that you enjoy this issue of The Lunar Observer. In it, you will find articles by Rik Hill about Ptolemaeus and company and northern Mare Imbrium, and Alberto Anunziato tours a very interesting wrinkle ridge in northern Mare Serenitatis, the great rayed crater Glushko and the area around Arago. Darryl Wilson leads us on a path of color lunar imaging, with techniques to be added regularly. Rik Hill has added a number of images of the Lunar 100 numbers 91 through 100. Remember from last month, these are the most challenging of the Lunar 100 to identify. Several observers sent in reports on the very beautiful partial lu-nar eclipse of 2021 November 19. Enjoy the portfolio! As always, Tony Cook contributes another very interesting Lunar Geologic Change Detection article.
