78 meses
seguidos de observaciones lunares reportadas, desde agosto de 2015 no hay un
solo número de la revista especializada en observación lunar más importante,
The Lunar Observer, sin que haya observaciones y textos de nuestra asociación.
La revista se
puede descargar de la web de ALPO:
En la portada se
referencian los artículos de miembros de la SLA aparecidos en este número (ya
publicados en entradas anteriores), los textos y las imágenes de la Sección
Focus On (Mare Crisium) se encuentran en el número especial 23 de “El Mensajero

in this Issue 103 Wishing each of you a very Happy New Year, and hoping 2022 is
a good year for you and your family. Thank you for reading this issue of The
Lunar Observer. In this issue, 26 contributors in 10 countries submitted 114
lunar images, drawings and articles. Thank you so much! Rik Hill took us on a
tour around Albategnius and Mare Crisium. Darryl Wilson continues a series on
lunar color imaging, with much interesting information. Robert H. Hays, Jr. added a beautiful sketch and
article about Picard and Mare Crisium. Alberto
Anunziato provided articles about the crater Hall and Dorsa Heim. Alberto also
contributed two extensive articles about this month’s Focus-On topic, Mare
Crisium. It is quite a task to coordinate all the observations that he gets,
and to put together such interesting articles. David Teske looked at Mare
Crisium from a collection of older lunar atlases. It turns out we are taking
some very fine lunar images today! As always, Tony Cook provides another
insightful article on Lunar Geologic Change as well as putting together the BAA
Lunar Circular. I hope that you enjoy this issue. Remember at the end of this
issue are announcements for future Focus-On subjects.

Las observaciones del eclipse parcial del 19 de noviembre de 2021
desde Oro Verde (Luis Francisco Alsina Cardinalli) y desde Santa Fe (Daniel
Mendicini, Rodrigo de Brix y Jorge Coghlan) permitió analizar no solamente los
reportes de antiguos FLT relacionados sino también el brillo relativo de los
distintos cráteres con iluminación al 100 % (con las imágenes obtenidas antes
del eclipes), de menos a más brillante:
Plato (144), Kepler (186), Copernicus (198), Aristarchus (129),
Tycho (129), Censorinus (216), Proclus (222) y la mancha brillante cerca de Hell
(225)
