News and Video

The event occurred just after 4AM local time, so most people were sleeping and didn’t see the bright flashes of the fireball, but multiple people in the area reported being woken by the loud booms that followed.

The sky lit up so bright it was almost daylight and there is a burning smell about 20 minutes afterward.

Reported by Gabby R. to the American Meteor Society

StrewnLAB Maps & Data

The trajectory of this meteor was solved by Jim Goodal from videos published online and the trajectory solution was run through the StrewnLAB software to predict the search area shown below. Please download and review the Google Earth files below for detailed maps of the search area.

2024-12-18 05:13 UTC V3: Trajectory solved from video, looks like a good match to the Doppler, but not very precise. Waiting for find coordinates from the field.

2024-12-19 16:56 UTC V4.1: Lower end height measured at 13km, based on two videos. The resulting strewn field matches very well with find coordinates. Waiting for find coordinates to be released by source.

Main Mass Search Area

End height for this meteor was measured at approximately 13.3 km, so it is very possible a larger mass is yet to be found. Our StrewnLAB software attempts to estimate the maximum size of the main mass, based on the end height and for this fall the maximum theoretical mass was 17 kg! Based on this, I wouldn’t be surprised to see a 5kg mass found, or larger. For our VIP subscribers, I have posted the following main mass search area:

This file contains the predicted search area for masses in the 1 to 10 kg range only. Additional mass ranges available upon request to Team Strewnify subscribers.

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.
