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. 相似文献

In order to further observing programs aimed at the possible meteor storms of November 1998 and 1999, we describe here how
the Leonid shower is expected to manifest itself on the sky. We discuss: 1) the expected wavelength dependence of meteor (train)
emission, 2) the meteor brightness distribution and influx, 3) the stream cross section, radiant and altitude of the meteors,
4) the apparent fluxes at various positions in the sky as a function of radiant elevation as well as 5) the trail length and
radial velocity, and 6) the diameter and brightness of persistent trains as a function of radiant elevation. These topics
were chosen to help researchers plan an observing strategy for imaging, spectroscopy, and LIDAR observations. Some applications
are discussed.
