Virtual Moon Atlas This software is the result of the collaboration between Christian Legrand, a passioned lunar observer, co-author of the guide ' Découvrir la Lune ' published in French by Bordas and in German by Kosmos under the title ' Der Kosmos Mondführer ', and Patrick Chevalley, author of ' Cartes du Ciel / Sky Charts '. The Lacus Excellentiae region is illuminated until 20 August, and then after impact from 4 SeptemberĪ useful tool for planning your observations is the Virtual Moon Atlas (VMA/AVL).This means a circular crater on a Clementine map may look elongated with a Position Angle≠0 when you observe the Moon Clementine maps are 'as seen' in lunar coordinates, in nadir view.Virtual Moon Atlas (VMA/AVL) maps are 'as seen' in (RA, DEC) on the sky, lunar coordinates projected onto the sky.Clementine maps show the S1C-R position, and VLO maps show relative crater locations and names in the region of S1C-R.Note: Near S1C-R, a pointing change of 0°W, 0.1°S on the lunar surface equals (RA, DEC)=(0.12' E, 1.0' S) Note: in this table NW in Lunar Coordinates equals NE in Right Ascension (+) and Declination (+) * Illumination at time of impact: E=Earthshine, S=Sunlight Northern crater of group of 3, use central peakĭifferent shape, crater has collapsed terraces Tiny crater NE of U-feature, NW of Clausius

Location and Description of Moon FeaturesĮarthshine-lit Pointing Checks, Offsetting to S1C-Rįresh basalt ring, easily recognized at Full Moon Spectra: To calibrate spectra, use locations of known or well studied mineralogy. Measurements through various filters are useful (for instance at 400, 450, 500, 550, 750, 900, 950, 1000 nm) or in infrared if you have that possibility. A list of mineralogy calibration craters is given in the table below. Images: To calibrate images, use mineralogy calibration targets. For the same 3 times, a close-up view of the region around the impact site is also given with the features from the above roadmap labelled. Click on image for the high-resolution version. The below set of images shows the phase of the Moon at 3 times: one day before impact, at the time of perilune on the forelast orbit and on the nominal impact time. To check pointing accuracy in Earth-shine lit Moon Lehmann C (if albedo Clausius too low in Earthshine)ĭrebbel D (if albedo Clausius too low in Earthshine) To verify pointing to locations on the Sunlit Moonīullialdus central peak (CP). Follow the bright Tycho ray to (RA,DEC) = (North,East) towards terminator When you are also taking images, it is useful to take images of the different features along the way, as these can be used for calibration. The details of the Moon features stated in the roadmap are given further down this page. It takes into account sunlit features on 3 September but can be adapted to other observing times. The last entry is L100, the magnetic swirls of Marginis Sea.For observing the region of the Moon around the SMART-1 impact sites, a roadmap to navigate along with your telescope is set up. Starting from L4 we have geological features, such as craters ( Tycho, L6), valleys ( Vallis Schröteri, L17) and mountains ( Leibnitz Mountains, L96).

The Moon is L1, L2 is Earthshine, 元 is the contrast between the dark seas and the lighter highlands. The objects listed include craters, seas, mountains and other features, and are arranged in ascending order of observational difficulty. With this selection, Wood tried to give astronomy fans a list similar to the Messier catalog of deep-sky objects, but of a more familiar object, the Moon. Wood in the article The Lunar 100 in Sky & Telescope magazine, April 2004. The list was first described by Charles A. The Lunar 100 (L100) is a list of one hundred of the most interesting features to observe on the Moon.
