We are shadow chauvinists. Most lunar images are shot near the terminator where the low illumination highlights subtle variations in topography. This is an excellent way to discover small features and results in dramatic images. But high-Sun views are also needed to reveal variations in albedo (reflectivity) of surface materials. Mare Serenitatis is one of the most pronounced areas of abrupt albedo changes, with the dark collar representing a different mare unit than the brighter material in the center of the mare. And the Apollo 17 landing area (bottom right) is even darker because it is veneered by pyroclastic material. Rays and wispy bright streaks also show up only when the Sun is high. We have [[May_28,_2004|previously]] discussed the uncertain origin of the ray that seems centered on Bessel in the bottom center of Serenitatis, but what are the sources for the crossed streaks at upper left? Rays also identify oblique impact craters - is that a small one near the Apollo 17 landing area? Brightness from steep slopes often makes small rilles easier to see, and here, in the lower left corner, the edge of the Buckland mare ridge is strangely bright - does it have a small steep slope? I encourage imagers to capture high-Sun, high resolution views of every piece of the nearside, both regional perspectives like this, and closeups detailing specific features. The best Earth-based [http://www.lpi.usra.edu/resources/cla/maps/part_ii/ high-Sun] photos of the Moon are the 40 year old images in the <em>Consolidated Lunar Atlas</em>. That <em>Atlas</em> used to be the best for [http://www.lpi.usra.edu/resources/cla/maps/part_i/ low-Sun] images of the Moon, but amateurs have exceeded its resolution. Its time to do the same for the high-Sun views.<br /><br />

2. The bright ray pattern to the northwest of the [http://the-moon.wikispaces.com/Apollo+17+Site Apollo 17 Site] is associated with what the IAU calls [http://the-moon.wikispaces.com/Catena+Littrow Catena Littrow] -- near pixel 769,497 in the LPOD photo -- possibly the crater formerly known as <strong>[http://the-moon.wikispaces.com/Littrow Littrow] BA</strong>. Paolo's image is indeed an improvement in resolution over CLA [http://www.lpi.usra.edu/resources/cla/info/cii/ Plate cii], taken from Earth with nearly identical lighting; but of course, the Earth-based CLA plates have also been superseded by excellent space-based high sun views of much of the equatorial zone by [http://the-moon.wikispaces.com/Apollo+program Apollo] and pretty good high sun views of the entire Moon by [http://the-moon.wikispaces.com/Clementine Clementine]. For those who might wish to overlay today's LPOD on the CLA plate or the Clementine mosaic, calibration data is available on the [http://ltvt.wikispaces.com/LPOD+Notes#29Jun2008 LTVT Wiki]. <!-- ws:start:WikiTextUserlinkRule:00:[[user:JimMosher]] --><span class="membersnap">- [http://www.wikispaces.com/user/view/JimMosher http://www.wikispaces.com/user/pic/JimMosher-lg.jpg] [http://www.wikispaces.com/user/view/JimMosher JimMosher]</span><!-- ws:end:WikiTextUserlinkRule:00 --><br /><br />

3. This may sound crazy, but what if the Bessel ray is from Bessel itself. A [http://www.mapaplanet.org/explorer-bin/explorer.cgi?map=Moon&amp;layers=moon_clementine_ratio&amp;west=14.8&amp;south=20.65&amp;east=22.77&amp;north=24.63&amp;center=18.785&amp;defaultcenter=on&amp;grid=none&amp;stretch=none&amp;projection=SIMP&amp;advoption=NO&amp;info=NO&amp;resolution=90.4522613065327 ratio map close up] seems to suggest a possible pattern coming from Bessel itself. It would also fit with the material coloration. Menelaus seems to me to be ruled out because the ejecta would have been older material based on the Ratio. The Bessel ray seems made up of much younger material. The [http://www.mapaplanet.org/explorer-bin/explorer.cgi?map=Moon&amp;layers=moon_clementine_multi&amp;west=14.8&amp;south=20.65&amp;east=22.77&amp;north=24.63&amp;center=18.785&amp;defaultcenter=on&amp;grid=none&amp;stretch=none&amp;projection=SIMP&amp;advoption=NO&amp;info=NO&amp;resolution=90.4522613065327 mutlispectral] also shows some patterns suggesting an unusal ejection of material. If it is from Bessel the impact might be an oblique because there seems to be lack of material on one side. It wouldn't be the first time that odd ray patterns are caused by oblique impacts. Look at Oblers A with a streamer of material running across the mare. Of course I could be totally wrong as well. <!-- ws:start:WikiTextUserlinkRule:01:[[user:AndrewMartinSFO]] --><span class="membersnap">- [http://www.wikispaces.com/user/view/AndrewMartinSFO http://www.wikispaces.com/user/pic/AndrewMartinSFO-lg.jpg] [http://www.wikispaces.com/user/view/AndrewMartinSFO AndrewMartinSFO]</span><!-- ws:end:WikiTextUserlinkRule:01 --><br /><br />

4. Andrew - the Bessel ray is mysterious - it looks like it interrupts the ray, but also that Bessel has been surrounded by the mare lava that the ray lies on. Bessel doesn't look like an oblique impact crater and the ray seems too straight.<br /><br />
