I believe the Harvest Moon is the first full moon after the first day of Fall. I'm open to correction.
From here the moon looks like a big ol' cloud that... Oh. That is a big ol' cloud, doggone it.
I get confused. There's something to do with two full moons in one calendar month; I'm not sure if that's a Blue Moon or a Harvest Moon - but I think Slowboat is right.
It's just getting dark out now, and I don't think the moon will come over the eastern horizon for quite awhile this evening....but we'd like to see a cloud or two - our summer "monsoon season" consisted of exactly one half inch of decent spritz about 6 weeks ago.
