How to read this table

Times are UTC. P: D/R means disappearance/reappearance; lowercase means the target is near Occult's calculated visibility limit; Gr is a graze and M is a predicted miss. Mag v/r are visual/red magnitudes. % ill uses + for waxing and − for waning; Elon is lunar elongation. Sun/Moon Alt/Az locate the objects in the sky, while CA/PA/VA/AA locate the event around the lunar limb. A blank field means Occult did not supply a value.
