September 12, 2019 12:49:48 UTC – A large meteor came down over Europe and was detected by 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... as a half-kiloton event! There were clouds in the area at the time of the fall, so the local camera data was difficult to process precisely. Luckily CNEOS provided a trajectory, which ended up being fairly accurate. This event was definitely worth searching, because a meteorite was found the day after it happened!

We reported on September 20th, 2019, there was a Rock Found Near Flensburg…, but details of the find were not released until later on the German forum, Arbeitskreis Meteore e.V. that there was a ~25 gram Typically, meteoroids breaks apart during flight through the atmosphere. Much of the material evaporates in a process called ablation, leaving only small stones to find. Occaisionally, large meteor events can... located near Flensburg Airport the day after the event!
Read this initial reportt from Andreas Moeller, on AKM e.V. Forum:
As some of you have certainly heard, Sirko [Molau] gave a talk at the IMC in Bollmannsruhe, about the fireball over the North Sea and also reported on a possible find. The following happened: One day after the event, someone from Flensburg reported on the fireball reporting form with a photo of a meteorite he allegedly found. Afterwards, AKM contacted this person and examined the meteorite. I would like to mention here that the person has requested absolute discretion and the exact location of the meteorite is kept secret. For this reason, the Kong-Arrildshoj Park, in the western part of Flensburg is indicated as the find location. At this point, I would like to give a big thank you to Dieter Heinlein, who has worked hard to ensure that the find is scientifically studied. Maybe Dieter will write a few more details. Currently it seems to be a very light (~ 2g / ccm) CC [Carbonaceous Chondrite] with a striking rusty color. Here are two photos from Carsten [Jonas].As reported by Andreas Moeller, on AKM e.V. Forum, a German forum on atmospheric phenomenon [Translated from German]
You can also read more about the find on Karmaka Meteorites website.
This meteorite was classified as “C1-ung”, an ungrouped carbonaceous chondrite of petrologic type 1. This is an extremely rare type! In fact, there are only two other C1 chondrites in the Meteoritical Society database, one from Antarctica, and one from the Apollo 12 Moon Mission! That makes this Flensburg meteorite, the largest of its kind ever classified!
Data & Reports
The latest version of the A computer simulation program, written by Jim Goodall. For more information, please visit the StrewnLAB Page.... Bulletin includes location and density data from the find, described above. I would like to think that the Version 3 prediction was actually correct, but the probability of finding a carbonaceous chondrite was low and the map indicated it as such. I do include this possibility in my simulations, by generating 5% of the meteorites as carbonaceous, to represent the actual probability of that meteoroid material in witnessed fall data. You can read more about my simulation methods in the StrewnLAB and Monte Carlo articles.
You will find the latest StrewnLAB Bulletin and The geographic area where meteorites landed, from a specific meteor event. The strewn field size and shape are affected by the size of the event, the slope of the meteor,... KML or KMZ files are often used to share geographic data and they are most often used in Google Earth software.

Good Luck!
