A New (Old) Lunar Atlas
11.12.2004 | Lunnoe foto dnya
Amateur astronomers have observed the Moon for hundreds of years. Most have had no way to permanently record their observations, so we know only the few drawings that have been preserved by publication in ephemeral amateur journals such as the BAA's The Moon.
Overlooked Secondaries

During the 1940s and 50s, Dinsmore Alter, the Director of Griffith Observatory, was an important expert on the Moon. Alter is most famous for his reports of obscurations in Alphonsus. His beliefs about the Moon were rather typical of the period - that is they were wrong. Alter thought that most lunar craters were volcanic calderas.
A Long Valley

Along the southern shore of Mare Nubium is a long rille that might initially be thought of as basin-concentric, like those rilles along the edges of southern Mare Serenitatis. But the Hesiodus Rille...
Moon Over Jupiter Over Florida

It seems we are blessed to be living at a time when astronomical rarities happen one right after another: The historic Leonid storm of a few years ago, the close approach of Mars...
Up Close With Proclus
7.12.2004 | Lunnoe foto dnya
Proclus is one of the brightest - and thus presumably youngest - craters on the Moon. As the Apollo image on the right illustrates, Proclus has a very sharp rim crest and its 1060 m deep floor is filled with slump blocks (S) of material that has slid down its steep walls.
Seeing Red, and Blue and Yellow

In a posting yesterday, Danny Caes mentioned the USGS Map-A-Planet (MAP) online software, and I realized that that powerful capability should be more widely promoted. So, delaying the promised "Up Close with Proclus" LPOD another day, here is the Clementine multi-spectral view of the fascinating area described in yesterday's LPOD.
Ghostly Terrain

A broad line of ridges and half buried craters that I call the Lamont-Gardner Megadome Alignment (LGMA) is one of the Moon's unexplained mysteries. There are other ridges of ghostly craters, but this structure in northern Mare Tranquillitatis is perhaps the most bizarre.
Telemann Flows

Geologist study units (or formations) that have consistent characteristics and hopefully ages. Two major types of units on the Moon are impact basin deposits (as at Imbrium ejecta at Fra Mauro) and mare lavas.
A Cozy View of the Moon
3.12.2004 | Lunnoe foto dnya
Clouds are the enemy of imagers striving for high resolution lunar views, but the presence of clouds can transform the way we appreciate the Moon. Dodi's picture is somewhat mystical, but also, as she says, "cozy" and "relaxed".
Glorious Aristarchus
2.12.2004 | Lunnoe foto dnya
Speechless awe was my condition when I first saw this image of Aristarchus and Schroter's Valley. This is the best image of this area I have ever seen from an Earth-anchored telescope, and comparable in terms of drama to spectacular Apollo images.
