Night to July 25th a large meteor shone in the night sky over southern Scandinavia, and according to the Norwegian Meteor Network, the interest among the population has been great.
At an early stage, the network assumed that Finnemarka west of Lier municipality is a precipitation area for the meteorites.
– This is a large, locally hilly and wooded area that is challenging to search in, they write on its pages.
They say that meteors often fall obliquely to the ground while fragmenting, and therefore can leave meteorite rocks over a large area.
Now they have narrowed down the fallout area and show a map. The map can be found at the bottom of this article.

The meteor network explains that what is shaded in gray on the map is the area they consider most interesting.
– The wider red ellipse marks a larger search area that we also consider relevant, but with somewhat less probability of discovery, the network writes.
They also no longer exclude discoveries to the southwest or northeast, but consider the probability of finding something in these areas to be small.
– Any finds at the southwestern end of the search are expected to be meteorites of a few kilos, while finds in the far northeast are expected to be meteorites of a few tens of grams, but these are uncertain estimates, they write.
Although the mass of the object that entered the Earth’s atmosphere may have been around 100 kilos, only a small proportion will survive all the way down to the ground on Earth.
The Norwegian meteor network reminds that you can not apply in places where the right of public access does not give permission, without permission from the landowner.

How to search for meteorites
– What one should first and foremost look for are dark stones, often with rounded shapes (but not as pebbles), often the same shape as a clay lump with a thumbprint. If the stone has split, the inside is often light. Many meteorites are magnetic, but not all. A few meteorites consist of a lot of iron and are very heavy.
The network recommends looking for rocks lying on the ground in a place where they do not seem to belong.
If you find a meteorite, they recommend that you take pictures of it, note the place you found it and that you take it with you – preferably in a plastic bag that protects.
– Contact the Norwegian Meteor Network or the Natural History Museum for assessment. Look for more meteorites in the same area. It is allowed to bring meteorites found in open country where traffic is allowed under the right of public access, as long as they are easy to take with them, they say.
