Observer
NameSigne W
Experience Level1/5
RemarksWe first saw two very large cloud like smoke rings in a very dark sky. The top one was very light and airy in appearance and was expanding as it traveled to the north. The lower ring was much more dense, maybe 5degrees under the larger burst and it too slowly expanded and became fainter as it traveled to the north. We heard no noise with these and there were no meteor type tails, these were circular that kept expanding and got fainter as they traveled until they disappeared from view. They traveled in the direction of the 3 stars in the shapes of a triangle, then I heard the faint boom and the third cloud like burst appeared, expanded and disappeared. That one was much smaller then the other two. All were very cool. Have never seen anything like that. We wish we would have thought to try and take a photo.
