1. a solar eclipse
2. a supermoon which we would not normally be able to see because it's a new moon, but will be able to because of the eclipse. Oooh!
3. the equinox
Plus it's the first day of Spring (see here to read why it's no longer March 21). And, there are going to be super high tides around the Atlantic coast of France. There's not a room to be found in the key seaside towns as people gather to watch the phenomenon.
The next time this convergence of celestial events occurs will be when we're all dead.
Pity it's raining in Montpellier and we'll miss the main event.
Still, teachers will be happy. They won't have to worry about elfansafety, keeping their little charges intent on self-destruction by looking at the eclipse, as there'll be nothing to see.
Here is a video the Mont Saint Michel as an island again. It looks fantastic!
