This is a very good sighting. Although this might be mistaken as a lenticular cloud, it really is a saucer craft cloaked by vapors. The craft is 43 metre or 140 feet in diameter. The crew are Nordics which is a change from all the Reptilian craft of late. It launched from the Nordic underground base in Antartica and will return there. Their mission is to observe military bases and activity, find the location of nukes in particular and observe weather conditions. They like the Phoenix area and find it safe to appear to witnesses there.
