The Moon Tonight - 2/7 ~ 8:00pm (2/8/06 at 3:00UTC)
Rukl's terminator position tables at 218-219 of Rukl's Atlas shows the terminator should be at about 27.3 deg W lunar longitude at 3:00 UTC 2/8/2006 (8:00PM 2/7, tonight). Some potential lunar objects along that longitude line are: 1) Hortensius Domes 1° N.E. of Crater Hortensius at 6.5° N, 28° W. Rukl Map 30. (Larger aperature object) (Equator north region) Each dome is about 10km in diameter per Rukl's map scale. May occur later in evening around 9:00pm. 2) Dorsum Zirkel. 29°N, 24°W to 32°N to 28° W. Rukl Map 10. 3) Montes Riphaeus. 7°S 28°W. Rukl Map 41. (Equator south region) 100km long mountain chain. 4) (Later at 10:30pm) Rima Hippalaus. 25°S, 29°W, Rima Agatharchides 20S°, 28°W. Rukl Maps 52-53 (Larger aperature objects) S.E. of C. Bullialdus. 150km fracture zone on lunar west (celestial east) side of Mare Nubium. 5) Rima Hesiodus. 30°S running E-W from 21°W to 27°W. Rukl Map 63. (Larger aperature object) Near southern edge of Palus Epidemiarum. 6) Crater Scheiner. 60.5°S 27.8°W (110 km dia.) Rukl Map 72. Lunar west (celestial east) of Crater Clavius). - Canopus56 (Kurt) __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!

Kurt, can you send a link to the map? Thanks! -- Joe

Unfortunately, Rukl's Atlas of the Moon is in book form only, available from Sky Publishing. http://www.amazon.com/gp/product/1931559074/qid=1139358835/sr=1-1/ref=sr_1_1... They may have one down at Barnes & Noble or at Clark Planetarium. For a quick last minute end-of-work-day printout, I would use the Inconstant Moon online atlas, Inconstant Moon Atlas by Kevin Clark http://www.inconstantmoon.com/atlas.htm Chart D2 - Hortensius Domes aka "Domeland" Chart E2 - Montes Riphaeus Chart F2 - C. Bullialdus. - Rima Hippalaus. Rima Agatharchides (Larger aperature objects) S.E. of C. Bullialdus. Chart H2 - Crater Scheiner. You probably won't be able to find the other objects on the list without more detailed charts. - Canopus56 (Kurt) P.S. - My general spiel on lunar charts: The best freeware option is Chevalley, P. 2006. Virtual Moon Atlas. (Freeware) http://www.astrosurf.com/avl/UK_index.html It's by the same guy behind Cartes du Ciel. I use hard-copy for the Moon, but "VAM" is a quick-n-clean Windows install and will blow your socks off. Here's my link list to online lunar maps: Lunar Planetary Instit. chart catalogue http://www.lpi.usra.edu/resources/mapcatalog/ Inconstant Moon Atlas by Kevin Clark http://www.inconstantmoon.com/atlas.htm Observatorio ARVAL - Moon Map http://www.oarval.org/MoonMapen.htm USGS. 2006. Near-side Color-Coded Topography Map of the Moon. (Web-document) http://planetarynames.wr.usgs.gov/luna_ccsr.html USGS Map-A-Planet http://pdsmaps.wr.usgs.gov/maps.html More detail charts, use the LPI (Lunar-Planetary Instit.) LAC (Lunar Aireal Chart) catalogue. They are as detailed as Rukl's Atlas, but frankly they are a major pain-in-the-$ss to print out. For example, here's a link to the LAC-58, Copernicus, which has the Hortensius Domes in the lower right hand corner: http://www.lpi.usra.edu/resources/mapcatalog/LAC/lac58/72dpi.jpg (0.9megs) - in http://www.lpi.usra.edu/resources/mapcatalog/LAC/lac58/ The LAC maps are as detailed as Rukl's Atlas (the base drawings for Rukl's Atlas are the LAC Charts), but Rukl's indexing, additions, and portability make it worth the money. The LAC maps were developed in the 1960s with your tax $ to support the Apollo missions. The LPI also has a variant on the LAC maps called the "Geologic Atlas of the Moon." The Geologic Atlas are the LAC charts color coded by lunar geologists: http://www.lpi.usra.edu/resources/mapcatalog/usgs/ - at http://www.lpi.usra.edu/resources/mapcatalog/ These are my favorite lunar maps - outside of Rukl - the GAM color coding really makes the interesting stuff stick out of the chart. In short - - spend the $30 and buy a Rukl. - load VAM on your astrocomputer __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!
