The results and conclusions are startling, and can be summarized in the following table:
As the table demonstrates, 85% of the observed phenomena shows (external) plasma characteristics (including 5% geometric shapes). The remaining 5% of the observed phenomena shows characteristics of solid, structured objects (and 10 % of uncertain character).
Teodorani explains the results in this article
A fundamental result which was ascertained directly on the field during two intensive scientific missions, is just that the Hessdalen phenomenology is characterized by two well- distinguished aspects:
- the very most part of luminous apparently immaterial orbs for which an external plasma appearance has been ascertained, but with highly anomalous characteristics both thermodynamically and morphologically,
- a slender but significant minority of objects which possess sharp characteristics of solidity.This double way in which the learnt phenomenology appears can be interpreted only in two alternative ways: or like an overlap of two phenomena with sharply different characteristics, OR like two sharply different behaviours of the same phenomenon.Anyway it must be reminded that, by assuming that the second option is taken into account, well-known laws of radiation physics say very clearly that the instrumental verification of the plasma nature of a given phenomenon, is not sufficient to demonstrate that the phenomenon is a plasma entirely, but only that his external surface (or: photosphere) behaves like a plasma which, by its nature, is able to hide all what exists inside it, as any photon coming from the interior should be immediately absorbed or scattered by the cloud of ions and electrons which are located in the external region, which in its turn is the only one which can be monitored instrumentally. In order to try to penetrate inside the plasma cloud, during the next missions, an “imaging radar” is planned for use, together with a high-resolution spectrograph  able to furnish a much more precise quantitative description of the plasma photosphere of the phenomenon
Since the first field-observation in Hessdalen (EMBLA 2000) it has been possible to learn that, together with a big majority of lights of the “plasmoid type”, structured objects were present too: at first a triangle of lights, then a low-luminosity egg-like translucid object . During the second field-observation (EMBLA 2001) something similar to a flattened ellipsoid was recorded . All these specific evidences of “structured targets” do not demonstrate at all, of course, that Hessdalen is subject to ET visitation.
On the contrary it is even more reasonable to suspect that the governments which are at present possibly experimenting flying devices working with “exotic tecnology”, would choose locations just like Hessdalen in order to work with no disturb by putting into practice the best of the camouflages. The co-existence of anomalous lights of possible natural origin linked to the territory and of flying machines born from some mind of the “Skunk Works” might permit to some government to operate in total secret by letting the public opinion believe that Hessdalen is an alien basis.
Therefore, the fact that some “structured events” in Hessdalen were recorded by EMBLA, is not a proof that Earth is visited by exogenous probes. Nevertheless this possibility in itself, as a pure work-hypothesis, is not at all excluded by official science, and it is included inside the plans (introduced before) of the SETV project. As it has been said, Earth may be reached in several ways which are canonically accepted. In order that this possibility may be proved or confuted, it is necessary to expand of at least an order of magnitude, both the sophistication and the completenesse of the sensing instrumentation.

Here it is worth noting that Teodorani keeps the door open for the SETV hypothesis (extraterrestrial visitation), but suggests that secret experiments with exotic technology are a more likely explanation.
My tip is exotic (man-made) technology. More on this in later posts.
