Steven: I did watch the video clip and would disagree with your above statement for the following reason... As a graduate student in the late 80's, I worked at the Atmospheric Sciences Center of the Desert Research Institute: http://www.dri.edu/index.php?option=com_content&view=article&id=115&Itemid=127 (now called the Division of Atmospheric Sciences) which is the research branch of the University of Nevada system. I worked under Dr. James Telford who was an expert in cloud microphysics (over 100 peer-reviewed publications). Clouds are NOT uniform stable structures; in fact, they are quite turbulent, with regions (turrets) of rising air columns (due to the fact that moist air is LESS dense than dry air) surrounded by descending (drier) air columns. If the diameter of the ring was much smaller than the dimension of the immediate cloud structure, I'd say you might be right and the ring was simply the boundary of one of the inherent structures of the cloud; but from what I saw in the video, the dimensions of the ring were quite substantial compared to the cloud, and therefore I think it unlikely to be so SHARPLY defined and consistent over the time of the video... i.e., the turbulence would have blurred the boundaries, if not disrupted them completely. -Mark -----Original Message----- From: OrionWorks [mailto:[email protected]] Sent: Wednesday, June 17, 2009 8:28 AM To: [email protected] Subject: Re: [Vo]:Smoke Ring?

It sure looks like a smoke/vapor ring to me, meaning it would appear to be derived from a natural phenomenon. I gather a major reason some appear to consider the apparition artificial in nature or deliberately manufactured (presumably by some advanced intelligence, i.e. our friends originating from Zeta Reticuli ;-) ) is that the apparition seems perfectly circular in its geometry. I think the reason I'm inclined to assume that the "ring" is a natural phenomenon is that it remains stationary in the sky. The fact that it also appears to be perfectly circular does not immediately suggest to me that it is artificial in nature. It's my understanding that many things in nature will assume a perfectly circular geometry precisely because a circle/sphere is the most energy efficient/economic topological surface to assume. Bubbles are a perfect example of a perfect sphere. Few here would assume that bubbles are the result of intelligently piloted craft! BTW, there was marvelous you-tube video someone on this list shared many months ago showing dolphins creating exquisitely formed bubble rings. What was extraordinary about this behavior was the fact that these dolphins seemed to "know" precisely when and/or how to disturb the ring in order to split the bubble vortex into two independent rings. One can not help but acquire the sense that cetations possess an incredible amount of intelligence - to be able to form and manipulate these playthings. It was sheer play for them. Of course, Douglas Adams had plenty to say on the subject of just how intelligent dolphins are. "So long! And Thanks for all the fish!" The point behind this meandering follow-up post is the fact that the bubble rings these dolphins were manufacturing, once formed, were exceedingly stable as they traveled through the much more dense medium of water. They were quite circular as well. Now, consider the fact that atmospheric "smoke" rings have less viscosity to deal with, and it seems natural for me to assume that such phenomenon can remain stable in the sky for quite a while before eventually dissipating.
