Hessdalen lights

[JMA]

Hi,

I'm looking for skeptical opinions about the Hessdalen lights. See for some informations this webpage:

http://www.ufoevidence.org/documents/doc1847.htm

The ufologists seems to think that Hessdalen lights are part of the UFO phenomena, and that if the skeptics can't explain this light it's some proof of the reality of UFO...

Well, I really don't know that well the Hessdalen files, so if you have some insight in this subject...

The dominant skeptical explanation seems to be that the lights are a sort of mirage caused by sharp temperature gradients between cold and warm layers of air. Proponents of this explanation, reject the close-range accounts of the phenomenon which are invariably anecdotal.

While still some contended that the lights are the result of a naturally occurring phenomenon, the piezoelectric effect, discovered by Pierre Curie in 1883. In this case critics contend that the mountainous region is made up of mostly rocks containing quartz that expand during the day and contract at night, due to thermal expansion. This expansion and contraction creates stress on the quartz crystals which in turn is converted into voltage that is accumulated over time until it is then discharged into the atmosphere creating a ball lightning effect.

Is there evidences that in the Hessdalen area there is quartz (because I think the sentence apply to the Marfa Light in Texas)?

I know it's very a very basic question, but I'm a dummies in this subject...

The Hessdalen phenomena has been the focus of some investigation by people at my current college. I don't know much about it myself, but they have a project page in English: http://www.hessdalen.org/index_e.shtml

Thanks.

I'm a little bit surprise that there is not more interrest about this kind a subject on the forum. I mean: it is a strange phenomena and it has implication for explaining some ufo sightings...

I'm reading for the moment a book about the Min Min phenomena explaining some sightings with Barn Owls luminous phenomena:

I don't really know what to think of all that...
