          Lunar perigee
                2011

Jan 22, 0:11    362,792 km
Feb 19, 7:28    358,246 km
Mar 19, 19:10   356,577 km
Apr 17, 6:01    358,087 km
May 15, 11:19   362,132 km
Jun 12, 1:43     367,187 km
Jul  7, 14:05   369,565 km
Aug  2, 21:00   365,755 km
Aug 30, 17:36  360,857 km
Sep 28, 1:02    357,555 km
Oct 26, 12:27   357,050 km
Nov 23, 23:25   359,691 km
Dec 22, 2:58    364,800 km

Whilst not exactly "a kilometre or two", it is
