LOS OBSERVADORES LUNARES DE LA SOCIEDAD LUNAR ARGENTINA EN “THE LUNAR OBSERVER” DE ABRIL 2020

Tendríamos que reflexionar sobre la importancia que tienen nuestras observaciones a nivel mundial, sí, a nivel mundial. Basta con leer “The Lunar Observer” para percatarnos el protagonismo que tienen la SLA y la LIADA. Ya van 57 meses seguidos en los que nunca hemos faltado.

Key to Images in this Issue 43

In the April 2020 issue of The Lunar Observer, amateur astronomers from across the globe continue to submit outstanding drawings, images, and articles about our nearest neighbor in space. Because of the Covid-19 outbreak and many people locked down, the number of observations is down some from previ-ous months. Hopefully, people can continue to get out some to do some lunar observing. Be careful and safe out there!

Robert Hayes Jr. takes us on a tour of the Fauth area while Alberto Anunziato and Sergio Babino explore the Tycho area. Read this and find a new “Lunar X”! David Teske had a nice look towards the far-side of the Moon in an article about the crater Bailly and beyond. As always, Tony Cook presented an interesting look at Lunar Geologic Change. Plus as said above, many spectacular images of the Moon are presented in the Recent Topographic Studies. Looking ahead, check out the ALPO conference details this coming November.

Anthony Cook se explaya sobre una observación visual de Alberto Anunziato de eudoxus para analizar un reporte de FLT de 1988:

Various craters have been arrowed for identifi-cation purposes. (Top Left) A sketch of Eudoxus made by Alberto Anunziato (SLA) on 2020 Feb 29 UT 21:13-21:33.
