You'll notice that we in the Uk are due a blue moon on June 30 (at 1349 BST) unfortunatey it sets at 0300 and rises again at 2159 (in the london area) so you'll have to look early or late to see if it is blue!
However all that day you can expect all those rare phenomena to occur. Maybe SWMBO won't have a head ache. Maybe a blue moon and blue pills day. /forums/images/graemlins/grin.gif
