Cockburn Island, Ontario, Canada

Tolsmaville, Ontario, Canada – Friday, June 19, 2026, 8:13 PM local time, A daytime meteor was observed entering the atmosphere at a steep angle, ending above Cockburn Island (prounced KOH-burn) in Ontario, Canada and shaking the area with a loud sonic boom. This was a large meteor event and it fragmented into many pieces which were detected by Doppler radar on the eastern side of Cockburn Island.

Search Efforts

Search efforts are in progress by local resident, stay tuned here for updates.

For those who live currently on Cockburn Island, I would highly encourage you to search for these meteorites. Due to the steep angle of entry of this fireball and the low wind conditions, many of the thousands of meteorite fragments could be concentrated to an area of less than 100 hectares (250 acres). I have posted this map on my website as well, with KMZ files that can be downloaded to your phone (see instructions on my Strewnify website as well). If you have any questions, please let me know. https://www.strewnify.com/y20260620_00z_17t/

StrewnLAB Maps & Data

Meteorites from this event were positively identified on Doppler radar, with the highest concentration 2 to 4 km southeast of Tolsmaville. The search area is approximately 4 kilometers by 4 kilometers, in a wooded brushy area, with limited roads. The terrain is not ideal for meteorite hunting by any stretch, but due to the size of the event and the high meteorite fall density measured by Doppler radar, it is definitely worth searching, if you can get permission to search.

Due to the steep angle of entry of this fireball and the low wind conditions, many of the thousands of meteorite fragments could be concentrated to an area of less than 100 hectares (250 acres).

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.
