Common ground-based optical and radiometric detections within Czech fireball network
Abstract
This paper describes first results of common detections of fireballs by photographic cameras in Czech Fireball Network (CFN) and the new radiometric systems equipped with sensors with very high times and intensity resolutions placed at two stations of this network, Ondřejov Observatory and Kunžak. Since August 1999, when we started regular operation of two radiometric systems, we have detected 17 different fireballs. Eleven of them were recorded simultaneously by photographic cameras, another six were only single radiometric detections as radiometers can detect meteoric events also under cloudy conditions. From two most suitable common events we performed calibration of radiometers and we determined their sensitivity. We found significant differences between lightcurves of slow and fast meteors recorded by these techniques, and finally, we found substantial differences in shapes of lightcurves for fireballs belonging to the same meteor stream observed in only 2.5 hours time interval.
