There was more about the blue moon as two full moons in the same
month (incidentally it happens again this month). It was suggested that it
was a reference to the practice of printers of diaries who thought it
necessary to distinguish between the two full moons in the month by
printing their full moon symbol on the appropriate days (nights?) in
different colours, the "extra" one being blue.
I think this is a load of tosh, but .....
Anyway, a whole month without any full moon at all, as last month,
is much more interesting.
