Willow Beach, Arizona, USA – Monday, October 24, 2022, 6:53 PM , A meteor fireball was observed over Arizona, heading northwest toward Las Vegas, Nevada. Two distinct flashes and were observed before it ended at a height of 27km, over the Lake Mead area.

This was a good-sized fireball, with a good chance that meteorites reached the ground. There are land use regulations complicating the search efforts, but public land for searching is available. Refer to the sections below for details and search maps, which you can download to Google Earth.

Search Efforts

Search efforts went underway as early as October 26th, based on an early release Strewnify map. The search area was very large (even bigger than the map posted below), due to lack of good video data initially. Many people searched and nothing has turned up yet. However, the Arizona desert has a way of preserving meteorites, so it’s never too late to search this area, and you never know, you might find meteorites from a previous in the process.

Search efforts are complicated for this event, because the area crosses boudaries between various land management agencies, and the only sutible land for hunting is managed by the BLM (see links below).

StrewnLAB Search Area

We have solved several iterations of a trajectory solution, based on the videos and still images above. The latest trajectory solution was run through the StrewnLAB software to predict the search area shown below.

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.

Moderate winds from the NW elongate the strewnfield to the SE
