At least this one isn't being ignored by the PTB, but the Norwegian government has and is doing all it can to explain just what is causing these lights. Good for them!
The Hessdalen Lights

Sightings of this particular phenomenon go back as far as 1811 and occur in the Hessdalen Valley, which is in the middle of Norway. However, in the early 1980s, the lights became much more frequent, with a peak of nearly 20 separate reports each week. Since then, the sightings have decreased in frequency, with observations numbering 10–20 per year. Normally, the lights are either bright white or yellow and hover above the ground.
Various scientific studies have been commissioned to find out the source behind the lights, but no conclusive explanation has been found. (There are cameras stationed around the valley, set up to take pictures of any bright light.) Studies meant to refute some of the findings have pointed out a variety of logical explanations, including car headlights and mirages, though they admit that such things don’t necessarily explain every occurrence.
I think that it's great that the folks in Norway are continuing to study these lights and I do wish them the very best. However, since the lights have been around since the 1800s, I reckon that the answers are not going to be fast in coming!
Coffee inside one more time, due to the rain. However, I do have some oven fresh biscuits and some apple butter I'll share!
