We'll have two blue Moons in 2018--Jan. & March (without a full Moon in Feb.). The 2nd full Moon of Jan.(31) 2018 will be in eclipse at Moonset for us. Maybe if there is a great composite volcano eruption during that time frame, the Moonlight will scatter to blue from the dust. One can only hope...
