Östhammar, Sweden – March 16, 2021, 7:10 PM local time, cameras belonging to the Norwegian Meteor Network, detected a meteor, travelling southeast along the coast of Uppsala county in Sweden, and ending above the nuclear power plant at Forsmark. The event was small, but speed of entry was also relatively slow, so there is a slim chance of finding meteorites.

StrewnLAB Search Area
We have calculated a predicted strewn field, based on the published trajectory from the Norwegian Meteor Network. We have fair confidence in the trajectory, and atmospheric stability was good, so the search area should be accurate. Please download and review the Google Earth files below for detailed maps of the search area.
Weather Data
The weather data below is sourced from weather balloons, and publicly available via NOAA’s Integrated Global Radiosonde Archive (IGRA). This data is downloaded and post-processed by the StrewnLAB algorithm, to account for changing weather patterns and weather balloon drift. The plots have altitude on the y-axis, in kilometers above sea level. The wind speed below 10km has large effect on the drift of meteorites.
