During 17 out 19 years we have what’s called a Blue Moon. It’s when their are two full moons in one month. Tonight will be a rare Blue Moon on New Years Eve. It happens once every 19 years. The last time was 1990, and not again until 2028. Article. I think I will shoot this Blue Moon, if the weather complies. I’m also gaining the energy to try and get some interviews for the podcast :).
