Equinox
The spring equinox happened before I got a chance to blog about it. I have some interesting links to share about the relationship between Sun and Earth.
This one always fascinates me. Right now, the line between night and day is vertical on the map. In three months, it will be at its greatest slope. There is a similar depiction at time.gov, but Walker's site lets you select your choice of map as the base, with various weather images among the choices.
The Sun-Earth Day site at NASA is very polished and information-packed. You can spend a long time browsing here. This year's theme is Ancient Observatories. If I remember, I'll tune in to the webcast later today live from Chichén Itzá in the Yucatan Peninsula to watch the serpent descend the stairs.
