Elmshorn, Germany – Tuesday, April 25, 2023, 2:14 PM local time, A very bright daytime fireball was observed by many over northern Germany, falling nearly vertical, and ending less than 18km above the village of Elmshorn. Meteorites have been recovered from this event and strewn field density is very high. There are good chances of finding meteorites from this event!

Search Efforts

Local search efforts began soon after the initial finds were made known, and the European Space Agency has also organized a search team, focusing on the immediate area surrounding the finds. A team from the U.S. arrived on Thursday, May 4th, and more are likely to make the trip to Germany by the weekend. Much of the search area is residential, but there are also some fields to the west. As always, please ask for permission before searching private property!

If you have find data or information about searched areas, please contact Jim Goodall on Discord or Facebook Messenger.

StrewnLAB Maps & Data

We received some trajectory analysis data from Vincent Haberer, and we calibrated the the trajectory solution in our StrewnLAB software to match the first two published find locations (Karmaka). Wind drift is considered and the angle of entry, so the shape should be correct, but the exact center of the strewn field is unknown. The map below considers all available data to estimate the probability of finding meteorites, by location.

Strewn mass is difficult to estimate, but based on available data and finds, but a reasonable estimate would be <70kg on the ground, with an average strewn density of 2.4 kilograms per square kilometer. This is very high! For this reason, we have categorized this event as Class A, with a high probability of finds for meteorite hunters.

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 onthe drift of meteorites.
