Partial and annular solar eclipses are interesting.
Total solar eclipses are magical.
The sun turns into a gleaming jewel and all of nature around you enters another dimension. The animals freak out, the temperature of the air around you drops dramatically, your shadows morph and multiply into weird shapes, it feels like midnight with an ethereal glow.
You see the atmosphere of the sun glow in all chromatic glory.
You'll never witness anything else like it.
The drop in temperature was the most striking part for me. It wasn't just dark, it was night in the middle of the day for a couple of minutes.
