IWLOP #029 - Fracastorius
Since this crater intersects the Nectarian Basin wall, it formed after the Nectarian Basin impact but before the area was flooded with lava.

R1: Fracastorius - Oval/Almond shape to the crater on south shore of Mare Nectaris. North wall virtually non-existent with similar colour to the Mare.
C1: Crater M located near the centre line in lower half of the crater. Crater L was located in the upper half just off centre. The rille seemed to pass just north of crater M, extending east towards a small crater and ending on the crater wall near crater D.
NOTE: The crater floor north of the rille into Mare Nectaris was darker than the floor south of the rille. There was also a bright line (ejecta?) that ran NE to SW, especially noticeable below crater D.
