Eastern sky large flash star missing Super Nova?Camping,Star gazing; our elevation 5180ft. Eastern sky 1/2 way up off horizon.2 stars close together,1dim the other about 3times brighter. The dimmer one started flickering in brightness,which caught our eye. Then it started to glow(like a light on the verge of burning out), Just as bright as its neighbor,and then, A flash of light,(like an old flashbulb), Which spilled out into the sky. Temporarily drowning out, or blocking the light from its brighter neighbor. Followed by 2 waves (Orange in color),of 1/2 Arcs (like rippling water, but not complete circles)on opposite sides of where the star was, Which was gone from the night sky. There was no sound and did not cast a shadow. The Milky Way was passing in front of these stars. I know the date. But, this was no firework. Super Nova? I thought this would be on the news or the Web. But haven't found anything.
