A STUDY OF THE FRAGMENT DISPERSAL AND TRAJECTORY OF THE SAYH AL UHAYMIR 001 METEORITE SHOWER. ... We obtained hundreds of GPS find locations, analyzed the fragment distribution, and developed a model of the meteorite's trajectory. ... More than 2670 samples weighing more than 450 kg have been collected. ... Increasing fragment mass along track indicated a flight direction of 233o. The fragments' mass distribution was used to model the meteorite trajectory. ...

... The source exhibits a mas-scale structure which, according to the USNO multi-epoch monitoring at 2.3 and 8.4 GHz over the period from 1994 July through 1998 April, undergoes considerable changes in the brightness distribution and positions of the major structural features. Our image is qualitatively consistent with the structural pattern of the source. ...
