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

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.
