Will o' the Wisp / Irrlicht / Ignis Fatuus

I'm researching about this natural physichal/chemical phenomenon, which is known to occur where organic material undergoes natural decomposition.
The phenomenon is rare, is seen only in the dark (which means only night time) and is observed mainly in marshes, swamps, cemeteries (in the past) or wherever some decaying material is present under ground or water.
If you have experience or recent observation of this light phenomenon, which is normally described as a transient "cold flame", please contact me.
I'm collecting reports about this fact, and any recent sighting will be very helpful for my research.

Maybe you can contact Mark Vornhusen, i came across this page he wrote years ago:
http://old.meteoros.de/irrlicht/irrlichte.htm
As far as the page has been taken "offline" quite some time ago, i'm not sure if the contact adress changed meanwhile.

PS: I'm well aware that the picture is just a placeholder ;-)

Thanks, I've written now to him, but I've probably done the same thing time ago, because I already knew this page... ;)
I've a good amount of publications about this matter, but the last reports obtained from living witnesses date back some years.
This phenomenon was rare in the past, and now seems to be almost disappeared! :cry:

For interested people, a well made (but somehow enigmatic in my opinion, because it lacks the evidence of the proofs!) scientific article about Ignis Fatuus: http://www.sciencedirect.com/science/ar ... 2814016425

Sorry, I'm no longer able to find the whole article... :?

The snake painted resembles a "Kreuzotter"... :P

Here is it:

Very well done analysis of the soil contents, but my question is: who actually observed the unusual "luminous cloud"? Which are the proofs of the actual existence of this "cloud"? There are no pictures, no footages, nothing more then vague reports... :cry: And a luminous cloud is something very different from the usual appearance of a typical Ignis Fatuus.
Anyway interesting and at least for me fascinating! :mrgreen:
