Nuevamente los
observadores lunares somos protagonistas de la revista especializada en
observación lunar más importante del mundo, The Lunar Observer (74 meses
seguidos de observaciones y textos de nuestra asociación publicados allí)
La revista se
puede descargar de la web de ALPO:

Announcement Mare Crisium 73 Key to Images in this Issue 74 Hoping that this
finds you and your loved ones doing well. As I prepare the September issue of
The Lunar Observer, I look fondly to the pleasant autumn nights when weather is
often favorable at night for getting out with the telescope and doing some lunar
observing. Not too hot, not too cold, no bugs, just right! In this issue of The
Lunar Observer, you will find a number of interesting articles, images and
drawings. Robert H. Hays, Jr. features a new observation of Cysatus C and Deluc
G, plus some articles from past issues to re-examine. Rik Hill provides a study
of three fascinating areas, Heraclitus, Rima Hadley and Plato. Alberto
Anunziato looks at the remarkable crater Sirsalis E, a ghost crater on the
shores of Oceanus Procellarum and wrinkle ridges near Piazzi Smyth viewed in
light different than previous observations. The Focus-On Lunar 100 by Jerry
Hubbell and Alberto Anunziato features Lunar Targets 81-90 which includes
ever more challenging targets such as the Prinz rilles, the craters Humboldt
and Perry and craterlets in Plato. Tony Cook provides another thorough report
of Lunar Geologic Change and Detection. Many thanks to all who contributed so
much to The Lunar Observer, as always! Congratulations to Dr. Tony Cook, as he
will head up the British Astronomical Association (BAA) Lunar Section! Along
with ALPO, the BAA has a great lunar program. Tony will be editing the BAA
Lunar Circular newsletter. Good work Tony

En este número,
la Sección Focus On versa sobre los accidentes selenográficos incluidos en los
números 81 a 90 del Listado Lunar 100. Las imágenes correspondientes serán
incluidas en un número especial de “El Mensajero de la Luna”, adelantamos
solamente las imágenes que fueron seleccionados para ilustrar los números:
84 (Pitatus por
Marcelo Mojica)
85 (Langrenus
por Desiré Godoy)
Y una serie de
imágenes seleccionadas para ilustrar la sección central:
Herodotus (Esteban
Andrada-Eduardo Horacek)
Copernicus, Petavius,
Plato, Tycho, Gassendi, Mare Crisium (Jairo Chavez)
En la Sección “Lunar Geological Change Detection Program” (páginas 64
y siguientes), se reportan nuestras observaciones:
Level 1 - Reports received for July included: Jay Albert (Lake
Worth, FL, USA - ALPO) observed: Birt, Copernicus, Hevelius, Plato, Posidonius,
and Proclus. Alberto Anunziato (Argentina – SLA) observed/sketched/imaged:
Bessel, Censorinus, Copernicus, Mons Piton, Theophilus, and Tycho. Kevin
Berwick (Ireland – ALPO): observed: Proclus. Anthony Cook (Newtown, UK –
ALPO/BAA) imaged several features in the color, and the lunar surface in
thermal IR. Les Fry (West Wales – NAS) imaged: Babbage, Blancanus, Capuanus,
Longomontanus, Moretus, Promontorium Kelvin, Schickard, T. Mayer and Vieta.
Leandro Sid (Argentina – AEA) imaged: Cassini, Mare Anguis, Plato and several
features. Trevor Smith (Codnor, UK – BAA) observed Plato.
Una observación visual de Alberto Anunziato permitió analizar exhaustivamente
un reporte de FLT (Fenómeno Lunar Transitorio) de 1969 en Theophilus.
