It seems conceivable that once the sun exhausts its hydrogen supply and starts expanding, there could be a point where its leading edge envelopes the moon before it does the earth.
During that time, before the sun vaporizes the moon, that part of the sun would be between the earth and the moon. However, given the present knowledge of astrophysics, it seems to be empirically impossible for the entire sun to ever be in that position.
I guess another word for it could be the heliocaust.*
