Just below Tycho's eastern rim crest (at 2 o'clock and 4 o'clock positions) are smooth ponds of impact melt. Wes' remarkable image also shows that secondaries are concentrated on the east side of the crater, and a high Sun view demonstrates that there are fewer rays to the west. Tycho was formed by an oblique impact, with the projectile coming from the west. The forward momentum carried ejecta debris to the east, raking the surface with small impacts. It wouldn't have been a good place to be 109 my ago.
