Северное затмение в равноденствие Northern Equinox Eclipse

Свет от Солнца и от Земли Sunshine, Earthshine

Today's date marks an Equinox and a New Moon. Remarkably, while the exact timing of both geocentric events occur within a span of only 13 hours, the moon also reaches its new phase only 14 hours after perigee, the closest point in its orbit.

Полное солнечное затмение на краю света A Total Eclipse at the End of the World
