Undulating Orange lights, changing formation and shape.For the past three Nights my husband and myself have witnessed strange orange (fire like) balls of light floating in the sky. They seem to climb and sometimes disappear. This evening they were in the formation of a large triangle shape and then they switch to being in one line, then two objects went side by side. The lights all disappeared. throughout the whole sighting, they change shape and brightness.....We have no idea what these can be and thats why I googled them which then took me to your site.
