Comet/Tail
New York, on Jan 3, 2004

The first was taken Dec 31 between 3-4:00 PM. They have a rusty colored persona with a tail of rusty color as well and other debris too. The second was taken between 1:30-3:00 PM. Moon swirls seem to have comet tails. The third and fourth were taken with cloudy skies Jan 3 at 2:00 PM.
