When it occurs, a solar eclipse is visible over only a portion of the earth. In order to see it, you must stand: -- at a place on earth where the eclipse will be visible, -- outdoors -- in the daytime, i.e. between the hours of sunrise and sunset
If you were standing on the Moon, it would be easy to notice a solar eclipse; the Earth would block out the Sun, all over the Moon, for an hour or so. On the Earth, we would have called it a lunar eclipse. From the Moon, it would be difficult to notice an Earth eclipse; the shadow of the Moon on the Earth, so obvious when you're in the dark at midday, wouldn't be so obvious from 250K miles away; a small dark circle on the Earth.
During a lunar eclipse, a resident of the Moon would experience a solar eclipse; the Sun would be hidden behind the Earth.
In the Moon's shadow. Particularly, the "penumbra" which is the lighter partial shadow, rather than the "umbra", the darker total shadow area.
The basic difference is when a lunar elise happens the earths shadow falls on the moon and therefore the moon is not illuminated, with a solar eclipse the moons shadow falls on the earth and the sun is covered by the moon. In both cases the sun moon and earth have to be 'in line'. Lunar eclipse; Sun, earth, moon. Solar eclipse; Sun, moon, earth. It is one of the great coincidences that the moons' size and distance from the earth almost matches the apparent size of the sun, hence we can have the type of total eclipse that we do. If the moon was any bigger or smaller or if it was more distant or nearer to earth this would not be quite the case.

That person would observe an eclipse of the sun.

If you were on one of Jupiter's moons, you would see frequent eclipses from the giant planet. Eclipses on Earth are caused by the moon.
A solar eclipse. Earth would cover the Sun from his point of view.
it would look small

Considering you can't stand on Jupiter and not sink it's a hard one to find out. It would vairy depending on where the moons were. But if you were to choose one it would be Lo
4 moons would go across the earth, and 109 earths would go across the sun.
