![]() ![]() The colors of the polygons correspond to the approximate weights of the stones that might be found. ![]() Map showing the modeled strewn field over the composite Doppler radar data. These were combined with wind information to model the area of impact. Yet few observations of the bolide were reported because the event occurred against the backdrop of a well-lit sky.īy the time the team arrived in Mission, TX late on the 16th, additional resources including videos, data supplied by the Meteoroid Environment Office at NASA Marshall Space Flight center, and data points from NOAA’s Geostationary lightning mapper, resolved the altitude, speed and trajectory of the bolide. The darker the shade the higher reflectivity value of the return.įries and Fries journeyed to an area in the Rio Grande Valley where sonic booms where heard from McAllen, west to Nuevo Laredo, and south, beyond the border into Mexico, the boom told a tale of solid material moving through the lower atmosphere. The colors reflect the strength of the reflection off surface area. Composite NEXRAD doppler weather radar returns of falling meteorites. A preliminary report was posted on the NASA website, showing sufficient evidence that space rocks may have survived to land on the ground. Oddly, they also coincide with the anniversary of the Chelyabinsk, Russia super bolide and the 2009 Ash Creek, TX meteorite falls.Īll three of the new events have also produced meteorites.įalling materials (possible meteorites) were identified the following morning from NOAA NEXRAD weather radar data by NASA Johnson Space Center scientist Marc Fries. The first on 13 February over the west coast of France, the second over Matera, Italy on Valentine’s day, and the third in the U.S. Article and images by Linda Welzenbach FriesĬoincidence or connected? Three February fireballs on three consecutive days. Loose pieces of black chert and fossil palm were sometimes mistaken for meteorites until the first real stones were found. The ground is composed of soft silt, sand and carbonate of the Miocene Goliad Formation.
