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

 

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:  http://www.alpo-astronomy.org/gallery3/var/albums/Lunar/The-Lunar-Observer/2021/tlo202107%2812_5MB%29.pdf?m=1624990530.

En la portada se referencian los dos artículos de miembros de la SLA aparecidos en este número (ya publicados en entradas anteriores):

Of coarse to our southern hemisphere readers, happy winter! I hope that this finds you and your loved ones well. I hope that the weather allows you to get out and do some gazing at our nearest natural neighbor in the universe. This issue contains great lunar articles by Rik Hill, Alberto Anunziato and Robert H. Hays, Jr., as well as numerous excellent images and drawings. The main part of this issue is the Focus –On the Lunar 100, targets 71-80. This includes targets such as volcanic areas in Atlas, saucer craters in Ptolemaeus and near limb basins Mares Smythii and Orientale. Also, there are some nice images of the recent lunar eclipse (pages 93-94). Tony Cook has again prepared another thorough report of Lunar Geologic Change and Detection. Thanks to all who contributed to these efforts. I have been busy this past month on all things lunar. I have been preparing a paper for the ALPO Virtual Conference of August 13 and 14. Please plan on joining this meeting! See pages 105-106 for details. Also, I have been scanning cards from Winnie Cameron for use by Tony Cook. I am now into the early Apollo days in my scanning project. It has been interesting to see the enthusiasm of lunar observers in thoe exciting times! Clear and steady skies!

Una observación visual de Alberto Anunziato y una observación fotográfica de Pedro Humberto Romano permitieron analizar un reporte de FLT (Fenómeno Lunar Transitorio) de 1975 en Aristarchus y la serie de imágenes tomadas durante el último eclipse lunar por Pedro Humberto Romano permitió analizar una serie de reportes antiguos producidos durante eclipses.
