Nope, that's a different phenomenom. That is simply sunlight
reflected from the day side of earth.

No, it's the total cloud cover on the day side that affects
it. 

The red glow of the eclipse is light refracted through the
earth's atmosphere into its night-time shadow onto the day
side of the moon.

The old moon in the new moon's arms is light reflected from
the day side of earth to the night side of the moon.
