Whether it's horns or an arch depends on timing. However, due to the consistency of the relative motions in play, horns on a sunrise will always get thicker as the moon moves past the sun. On the other side then, during sunset, an arch would similarly be getting thicker while the sun goes down and the moon moves past it.

What you can't have, for one example, is horns that get thinner during sunrise.

ORLY? Video here makes it look the other way around.

I think it looks thicker as it rises because the sun is getting brighter and therefore more overexposed. During an eclipse, the moon takes about 5 hours to traverse the full diameter of the sun. During a sunrise, the sun takes about 5 minutes to go from partially visible to fully above the horizon. So any actual change in thickness is negligible.
