LOS OBSERVADORES LUNARES DE LA SOCIEDAD LUNAR ARGENTINA EN “THE LUNAR OBSERVER” DE SEPTIEMBRE 2021

 

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:

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 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.
