Chika-san took photos in Iwaya-Iwakage on March 18, 2017, two days before the spring equinox. We showed you ten photos of the Iwaya opening, in Part 1. Here are ten spotko photos which correspond to those ten photos of the Iwaya opening. You can see the changes in the shape of the spotlight over the same 45-minute interval from 12:25 to 13:10. As more light is blocked by the middle megalith, the spotlight becomes narrower until it vanishes completely.
