Tonopah, Arizona, USA – Tuesday, April 16, 2024, 7:59 PM local time, a meteor fireball was observed heading south at 16 km/s, and ending at a height of 26 km above the Eagletail Mountains Wilderness. Due to the slow speed and low end height, meteorites are expected.

News and Video

Several videos of the event have been posted online and the story was covered by FOX 10 Phoenix.

The fireball is estimated to have weighed about 150 pounds. When it broke up, it released the same amount of energy as nearly two tons of TNT.

Search Efforts

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

Dr. Marc Fries of NASA noted “a single radar signature appears at 10km altitude”. For more information, please visit the ARES Meteorite Falls Page.

StrewnLAB Maps & Data

In addition to the posted NASA trajectory, I analyzed several videos and produced a modified trajectory solution, that 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.

2024-04-21 04:00 UTC – UPDATE V2: Modified the initial trajectory from NASA, based on available video.

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.

Mild winds from the northwest had a minimal impact on meteorite drift
