At the equinox the Sun crosses the celestial equator, so it rises almost due east and sets almost due west from everywhere on Earth. Equinoxes mark the astronomical start of spring and autumn.

Photography & observing tips
- •Check the local weather forecast a few hours ahead; thin high cloud ruins more sessions than rain.
- •Get away from direct lights, even if you cannot leave town — a shadowed spot helps enormously.
- •Red torchlight preserves the dark adaptation you spent 20 minutes building.
