Fröslunda, Uppsala, SWEDEN – November 7, 2020, 10:27 PM local time, U.S. Government sensors detected a large meteor fireball travelling ENE at 17 km/s, ending above the town of Fjärdhundra, in the Enköping Municipality of Sweden’s Uppsala County. Total atmospheric impact energy was equivalent to 330 tonnes of TNT!
The event was also detected by the Norwegian meteor camera network, and a trajectory was published at the link below. Considering the size, speed, and angle of the fireball, it is likely there are meteorites on the ground. Travel is restricted at this time, due to the global pandemic, so the search will be limited to local efforts. Good luck to the people of Sweden, and we hope to see meteorites in the news soon!

Norwegian Meteor Network
Video and News
There were several videos captured, mostly by the Norwegian Meteor Camera Network, that were useful in determining the trajectory of the meteor. These videos were also found on YouTube.
This was a fairly large event, and meteorite hunters from all over Europe visited the region, to join the search. In late February 2021, an impressive 14kg iron meteorite was found! If you would like to join the search and future events in this region, please join the Facebook group:
As noted in the press release from the Uppsala Allsky Meteor Network, if you plan to hunt for meteorites in Uppsala,
Respect the law, and note the following:
• Parking a car in the area is very difficult. If possible use the designated parking area. Do not park on
private property or block entries or exits.
• Red roads on the map are private roads, and should not be used.
• Always be well visible, wear a high-visibility vest.
• Do not visit the area when hunting is in progress, which happens relatively often in this area.
• Keep your distance to any forestry activity, at least 90 m.
• Do not enter any area or field that is in use, such as planted acres, or fenced areas with animals.
• You are not allowed to damage property. For example, only the land owner is allowed to dig.
• Using a metal-detector requires an official permit, and does not grant any rights to dig.
StrewnLAB Search Area
Two trajectories for this meteor have been published, one from The Center for Near Earth Object Studies (CNEOS), is part of the California Institute of Technology's Jet Propulsion Laboratory. CNEOS collects data from U.S. Government sensors, and releases it for... and one from a team in Norway, and this data has been run through the StrewnLAB software to predict a search area. Please download and review the Google Earth files below for detailed maps of the search area.
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 A computer simulation program, written by Jim Goodall. For more information, please visit the StrewnLAB Page.... 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.
