@Pavel Just to note, as seen in the bottom photo, the moon's shadow on Earth (during solar eclipse) is *much* smaller than the Earth's shadow upon the moon during lunar eclipses. In fact "terran eclipse" might be a misnomer -- the Earth can never be totally "shadowed" by the moon.

<p>A lunar eclipse on earth is a solar eclipse on the moon.
The earth takes up 2° of sky from the lunar surface (vs 0.5°), so you'd see less corona in your space suit. The moon's speed through earth's shadow is only about 1 km per second, so you'd have <a href="https://en.wikipedia.org/wiki/Lunar_eclipse" rel="nofollow">up to 107 minutes of totality</a>. What with earth's atmosphere, I doubt you'd see much in the way of <a href="https://en.wikipedia.org/wiki/Baily%27s_beads" rel="nofollow">Baily's beads</a>, but there'd likely be a spectacular round the world sunset glow to make up for that.</p>

<p>Solar and lunar eclipses are pretty straightforward. But what about eclipses when you are standing on the Moon? I have been trying to Google the info, but there's some gaming clan that has taken the name "terran eclipse" so it's hard to find the real stuff.</p>

But what about the other way - a solar eclipse observed from the Moon? What would Earth look like? Would anything special be happening on the Moon?</p>

A "terran eclipse" is just a lunar eclipse, observed from the Moon.

Trivia: a total lunar eclipse occurred shortly after Apollo 15. (The astronauts had already left.) [The mission report](https://www.hq.nasa.gov/alsj/a15/a15mr-4.htm) states the equipment left there recorded a temperature swing of 283 degrees F (140 degrees C) So expect it to get cold...

Not an answer, but a helpful piece of Google advice.  You can tell Google to omit results with certain words by adding a '-' in front of them.  If you search "terran eclipse -game -community", it gets rid of most of that stuff and the results contain more eclipse from the moon results.  It doesn't get rid of all of it, but with a few more terms ignored you can boil it down to just what you're looking for.
