The LOLA Quiz: Solutions and Winners
I am happy to announce that there have been lots of participants in the LOLA-Quiz. Here are the solutions to the problems, the names of those who got it right and also the name of the lucky winner.
All five regions were recognized and named correctly by:
-
Mirjam Boere from the Netherlands
-
Romain Letor from France
-
Fang Xiao from China
-
Daniel Garcia from Spain
-
William Sherwood from Canada
-
Tomohiro Yamaguchi from Japan
And! the! winner! is!
Mirjam Boere!!!!
Cheers for the winners, jeers to the losers. Nah, just kidding ... I hope all participants had a lot of fun.
So here are the five images, this time with correct axis ticks and titles. But first, a map of the entire lunar surface and a picture I took with my telescope, both showing the regions depicted afterwards, to facilitate orientation.
And now for the five regions:
Figure 1: East of Mare Nubium. The names of the craters in the row, from North to South: Herschel, Ptolemaeus, Alphonsus, Alpetragius, Arzachel, Thebit (west of this you can see the Rupes Recta when the solar elevation is low) and in the South, Purbach. East of Ptolemaeus: Albategnius and inside that: Klein.
Figure 2: In the southwest: craters Reinhold and Eddington. To the North Copernicus, and to the northeast of that Eratosthenes and the Montes Appenines. To the north of Copernicus are the Carpathians and Mare Imbrium, to the East, Sinus Aestuum. Even in this topographic view the ejecta blanket surrounding Copernicus is clearly visible.
Figure 3: This was the hardest one. But I did state that not all of the regions were necessarily easily observable. The area shown here is west of Ocenaus Procellarum. This is one of the libration regions, i.e., it is visible at times and not at others - an effect of the orbital eccentricity of the Moon. Note crater Lorentz of which only a large semi-circular structure remains.
Figure 4: The image is filled almost entirely by Mare Imbrium. In the southwest are craters Helicon and leverrier. In the Northeast the large crater Plato, which was filled with basaltic lava, giving it a smooth appearance.
Figure 5: Heavily cratered highlands in the south. Noteworthy craters are: Tycho (with central mount), Longomontanus, Maginus, Clavius (containing a chain of smaller craters, starting with Rutherfurd on the southeasterly rim). South of Clavius: Scheiner, Blancatus, Gruemberger and Cysatus.
