The equinox is coming! Notice how the line between light and dark on the equinoxes matches longitude.

Week #6: Sunrise on the Equinox |

Looking for a Clue?
When sunrise occurs at the Prime Meridian on the equinox, six Mystery sites will already have had sunrise and the other four will still be waiting. |
