May 2015 Dashed Spotlights and Sunbow

Kanayama was absolutely gorgeous in May this year. The “ten-ten-tenspotko (dash-dash-dash spotlight) showed up just as expected, although a bit tardy since this is leap-year. Here we show photos taken by me, Iwaya Rockbat, on May 21 and 22. We see the triangular face of the cut stone in the grotto of Stone A before and after the sunlight strikes it. We can see how the sunlight slants along the southern face at right angles to the triangular face. And finally, we see the five spots. ST’s hand points to the topmost spot, which is pretty faint in the photo. By taking a close look at the photo without the spots, we can understand that the surface has been deliberately carved with “bumps” which catch sunlight, creating dashed spotlights. Just remarkable, the ingenuity of the ancient megalith builders! 2015.05 154

On May 22, people in Japan and elsewhere (such as in Mexico City on their May 21) were delighted to observe a striking sunbow. Here are some photos taken of the sun above Kanayama Megaliths.
