Why is it rare? There's a full moon every month.

Basically the Harvest Moon is the full moon closest to the autumnal 
equinox. It rises soon after sunset. It is no bigger than most other 
full moons but it is definitely tinted orange. This is a true physical 
effect not an optical illusion. The passage of light through the 
thicker layer of atmosphere scatters the blue light leaving only the 
reddish portion of the spectrum. It makes a wonderful effect for 
photographers wishing to shoot a spooky Halloween scene
