En el mes en que
cumplimos el hito de ser invitados a disertar en la conferencia Anual 2020 de
la Association of Lunar and Planetary Observers del 2 y 3 de octubre,
celebramos 63 meses seguidos de observaciones reportadas y aprobadas por ALPO y
publicadas en su revista especializada de temática lunar: “The Lunar Observer”.

Mars Attacks! This month the members of ALPO will focus their attention on the
opposition of Mars. This will be our best view of Mars for many years to come,
so steal a look at the Red Planet while gazing at the Moon! I really should
title this Moon Attacks Mars, as we have a number of wonderful images of
conjunctions and even occultations of Mars by the Moon. Check out the Recent
Topographic Studies for these images. This issue of The
Lunar Observer contains articles on the Moon from Alberto Anunziato, Howard
Eskildsen, Rik Hill and David Teske. Also, there are many crisp images
of the Moon to study. Tony Cook has another very detailed look at Lunar
Geologic Change Detection. October 20, 2020 is the deadline for submissions for
the next Focus-On article. In the northern hemisphere, the autumn is a most
pleasant time to get out and enjoy the fall skies. Be safe out there and clear
skies.

En la Sección “Lunar Geological Change Detection Program” (páginas 55
y siguientes), se reportan nuestras observaciones:
Level 1 – All Reports received for August: Jay Albert (Lake Worth,
FL, USA - ALPO) observed: Birt, Copernicus, Hyginus, Mons Piton, Plato,
Posidonius, Promontorium Agassiz, Theophilus and Tycho. Alberto Anunziato (Argentina - SLA) observed:
Biot, earthshine, and Posidonius A. Walter Elias and
other AEA team members (Argentina) imaged: Aristarchus. Valerio Fontani (Italy
– UAI) imaged: Mons Pico and Tycho. Desiré
Godot (Argentina – SLA) imaged: Eudoxus. Rik Hill
(Tucson, AZ, USA - ALPO/BAA) imaged: Endymion and Meton. Trevor Smith (Codnor,
UK – BAA) observed: Plato and Plinius.
Level 2:
Eudoxus: On 2020 Aug 28 UT
23:45 Desiré Godoy (SLA) imaged this crater, using a 20cm refractor, and a QHY5-II camera with
a 742nm filter, under similar illumination and similar viewing angle to the
following report: On 1882 Jan 29 at UT 17:00-17:30 an unknown observer noted an
unusual shadow in Eudoxus crater. The Cameron 1978 catalog ID=227 and the
weight=2. Reference: Sirius Vol 15, 167, 1882. The ALPO/BAA weight=2. Figure 3.
Eudoxus as imaged by Desiré Godoy (SLA) on 2020 Aug 28 UT 23:45. Orientated
with north towards the top. As you can see from Fig 3, there is nothing unusual
in the shadow appearance in this crater. Alas I cannot find the Sirius journal on-line and so cannot glean much more
information about this report. We do not even know in which country the
observer was? For now, I shall leave the ALPO/BAA weight at 2.
Level 3:
Biot: On 2020 Aug 23 UT 21:45-22:00 Alberto Anunziato (SLA) observed visually this crater under
similar illumination to the following report: On 1969 Jul 19 at UT 16:00-18:01
Azevedo at al. (Joao Pessoa, PB, Brazil, 8" reflector) saw that the west
wall of Biot was unusually bright. Had seen it without
this condition several months earlier. This was from the Apollo 11 watch. Jose
da Silva says that this was not a LTP as the observers were inexperienced. The Cameron 1978 catalog ID=1163 and
weight=0. The ALPO/BAA weight=1. Alberto, using a 105 mm. Maksutov-Cassegrain
(Meade EX 105), at x154, found that the west wall of Biot was very bright but
that it looked normal, indeed very similar to the west wall of Biot A. We shall
therefore lower the weight from 1 to 0 and remove it from the ALPO/BAA LTP
catalog.
