2005 lunar occultations:

see http://skyandtelescope.com/observing/objects/occultations/article_1398_5.asp  for map which shows:

An occultation can be seen north of a red line or south of a blue one. A grazing occultation occurs along each line; tick marks at 10-minute intervals (increasing west to east) indicate the Universal Time of the middle of the graze. A circled A means the event is visible but the Moon’s altitude is too low for reliable timings, S means sunrise or sunset for bright objects, and T shows where twilight becomes too strong. B marks where a central graze occurs at the Moon’s north or south cusp and terminates the path (unless the star is bright enough that it might be observed against the sunlit side of the Moon).
