Search Efforts

This was a fairly large event and many fragments have already been found, so you can expect meteorite hunters to be actively searching the area for a few weeks. The meteorite material was classified as For additional pictures and detailed account of the search efforts, please visit Karmaka Meteorites.

StrewnLAB Search Area

A trajectory for this meteor was analyzed by BRAMON and run through the StrewnLAB software to predict a search area. Raymond Borges also provided our team with meteorite find data, which was helpful in verifying the trajectory and understanding the fragmentation profile. 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 on the drift of meteorites.

Fortunately, there was little wind at the time of the fall, meteorite drift was small.
