Abstract: | A daylight bolide was observed over Galicia (NW Spain) and Minho (N. Portugal) on March 1, 2005 at 15 h10 min ± 3 min UTC.
We interviewed 23 eyewitnesses of the event in order to obtain the azimuth, altitude, and slope of the fireball’s trajectory.
Reports suggest an atmospheric ending height below 20 km, indicating that meteorite survival was likely. From the reconstructed
trajectory and the fireball’s duration, we obtained the approximate heliocentric orbits for the meteoroid. Assuming an entry
velocity higher than 20 km s−1 which is consistent with its estimated duration, the meteoroid originated in the asteroid belt. |
