The creators of the video have put one too many T's in the name "Scotland"

When you capitalize the T, you're talking about Arnold.

Well, you have to admit, that would be interesting.

ISS hasn't seen an eclipse but Gemini XII did on November 12, 1966. The Wikipedia article has a partial eclipse photo, and there's a poor quality diamond ring photo on line. The Russian Mir station observed the umbra of the 1999 eclise in Europe but was not in the umbra itself.

Not having been one, I wonder if it affects their "daily life" in any significant way. For example, staying away from the windows at certain times? Do they take care not to face the sun on spacewalks, etc? (Surely looking right at Sol would be blinding, but we all have that, too. I'm wondering if it causes more trouble to their activities than it does us earthbound mortals.) With a couple of astronauts who have just begun a full year-long shift on the ISS, I wonder what their special concerns are in this regard.

The International Space Station, orbiting with an inclination of 51.6°, requires extra shielding to deal with this problem. The Hubble Space Telescope does not take observations while passing through the SAA.^[6] Astronauts are also affected by this region which is said to be the cause of peculiar 'shooting stars' (phosphenes) seen in the visual field of astronauts.^[7]

A terminator, twilight zone or "grey line" is a moving line that separates the illuminated day side and the dark night side of a planetary body. A terminator is defined as the locus of points on a Moon or planet where the line through a Sun is tangent.

umbra - The umbra is the darkest part of the Moon's shadow. From within the umbra, the Sun is completely blocked by the Moon as in the case of a total eclipse. This contrasts with the penumbra, where the Sun is only partially blocked resulting in a partial eclipse.

antumbra - The antumbra is that part of the Moon's shadow that extends beyond the umbra. It is similar to the penumbra in that the Sun is only partially blocked by the Moon. From within the antumbra, the Sun appears larger than the Moon which is seen in complete silhouette. An annular eclipse is seen when an observer passes through the antumbra.

penumbra - The penumbra is the weak or pale part of the Moon's shadow. From within the penumbra, the Sun is only partially blocked by the Moon as in the case of a partial eclipse. This contrasts with the umbra, where the Sun is completely blocked resulting in a total eclipse.
