There can be a big difference in how the Hessdalen phenomena look like.
The difference is so big that there might be different kind of phenomena we are facing.
These differencies can be seen both in the pictures and in the description from the observers.
The phenomena can be organised in different types, based on how it looks like, the movement and how it behaves.
Most of the descriptions, given by the observers, tell about a lightphenomena seen when it is dark outside.
That is natural, because it is easier to see a light when it is dark outside.
85 % of the raports gathered during the periode with highest activity, in the beginning of the 80'ies,
tell about a lightphenomena. The rest of the report use the word "object", and some of these were
seen during the daytime. Sadly, there are no pictures of these, but there are several pictures of the lightphenomena.
When the lights is best documented and in majority of the cases, we have choosed to use the word lightphenomena,
and we have programmed the aoutomatic station to react on lightphenomena. When we get more powerful
computers, we can program them to also react on phenomena seen on daytime. (We need more ekonomical support to be
able to do that.)
The phenomena can be devided in these categories:
White, or blue-white flashing light. They are usually high up in the air, close to the to of the mountains
or even higher. Their living time is usually short, typical some seconds. Sometimes they have been seen
for a minute, but seldom any longer time. The picture on the right is taken with a long exposure time. During that
time has the light flshed several times while it is moving. The camera has been on a tripod.
A yellow light, with a red light on the top.
This red light can be flashing. The picture on the right is taken with a long exposure time. During that time
has the light moved, and one red flash happened during this periode.
When the light is moving during the exposure time, you will see it as a yellow line on the picture.
It is also possible to see that the yellow light is not constant in intensity. The camera has been on a tripod.
A yellow or white light. This is the most common description of the Hessdalen Phenomena. This light can
stand still for more than an hour. It can move around slowly down in the valley, stop sometimes for minutes, start moving again.
The shape is often round as a ball. Sometimes there are other shapes.
4 - A black "object" with light on.
This has been reportet several times in Hessdalen.
To the right you can see a picture of such a phenomena. It was Leif Havik
who took the picture in Hessdalen on the 18.Mars 1982. It shows three lights on this "black object".
To the left for that picture you can see a drawing made by one
observer of a similar phenomena in Hessdalen. A "object" with a light on each end.
The four pivtures from the left is taken from a film recorded in Hungary around 1990.
It shows a light with a black area on, which is moving around on the light. In one part of the film is this
black area covering nearly the whole light, and then is it a black "object".
It is shown here for illustration, even if it is not recorded in Hessdalen, because it is
something similar as decribed of these phenomena in Hessdalen.
You can see the film here, a 3 Mbyte-avi
or a 44 Mbyte-avi verson. The speed of this film is half of the original.
The moving speed of this phenomena is then two times more than what you see on that film.
