Hello. This is my first post 
I found a pretty old topic about auras here but it was pretty bloated and old so figured I should start a new one.
What I'm wondering is, is there a universally accepted "skeptic" position on what the aura is/isn't, as well as what accounts for the colors in Kirlian photographs?
As The New England Skeptical Society says, "There is no doubt that Kirlian photographs themselves are not fakes; they are photographing something, the question is exactly what are they capturing."
I've read the skeptic positions on Kirlian photography, most of which deal say the colors result from a "Corona Discharge".
From http://www.netasia.net/users/truehealth/Kirlian Photography.htm:
That webpage also says that "Kirlian photographs are made by placing an object directly on photographic paper or film laid atop a metal plate to which high-voltage current is applied." So is this guy saying that the "corona discharge" is caused directly by the electrical current's effect on the body's moisture? Thus the colors surrounding a person's head are not actually present there and just invisible to the untrained eye but actually just show up on the image due to the electricity?
My central question is, does the "corona discharge" explanation rule out the possibility of there existing an actual aura around the human body, rather than just an illusory but actually nonexistent one displayed only as a result of the Kirlian photography process?
Where do you all stand on the topic of auras in general?

From http://www.netasia.net/users/truehealth/Kirlian Photography.htm:
Furthermore, there’s nothing supernatural about Kirlian photography. The manner in which it’s done can be explained by natural means. Scientists say the size and shape of the aura doesn’t correspond to a person’s health, mood or attitude but is produced by fluctuations in high-frequency current. The image on film is actually a corona discharge, a natural electrical phenomenon like the one found in flashes of lightning.
Gary Poock and Paul W. Sparks reported in Smithsonian magazine that there are at least 13 factors that can influence the Kirlian image. These include voltage level, voltage pulse rate, moisture, atmospheric gasses, the internal force and angle of the object held against the film, and barometric pressure. In effect, a single person can come up with different auras simply by changing finger pressure and the amount of moisture found in his or her skin. The more moisture there is, the larger and more colorful the auras are.
"Living things (like the commonly photographed fingers) are moist. When the electricity enters the living object, it produces an area of gas ionization around the photographed object, assuming moisture is present on the object. This moisture is transferred from the subject to the emulsion surface of the photographic film and causes an alternation of the electric charge pattern on the film. If a photograph is taken in a vacuum, where no ionized gas is present, no Kirlian image appears. If the Kirlian image were due to some paranormal fundamental living energy filed, it should not disappear in a simple vacuum," explained Terence M. Hines, a psychology professor, in Pseudoscience and the Paranormal.
"That the Kirlian image is enhanced by emotional arousal can also be easily explained by the presence of moisture. A basic physiologicasl response to arousal is sweating. Thus, aroused individuals will have greater moisture content on their skin surface and the greater amount of moisture will produce a larger Kirlian image," added Hines, a consultant of the Committee for the Scientific Investigation of Claims of the Paranormal (CSICOP).
Until Kirlian enthusiasts come up with better equipment, more rigid standards and more convincing proof that auras exist, don’t waste your time and money on them. For now, the auras they produce are, at best, works of art that belong in a museum - not in a hospital.
