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”).

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.
