| Description
| - Stereoscopic video and photographic observations of six faint and one bright Draconid meteors provided meteor morphologies, heights, light curves, and atmospheric decelerations. The spectrum of the bright meteor was also obtained. We developed a simple model of meteoroid ablation and fragmentation. The model assumes that cometary meteoroids are composed of constituent grains. We have found that the grain mass range was relatively narrow in all meteoroids but differed from case to case. Individual mm sized meteoroids contained tens of thousands to almost a million grains. The meteoroids were porous aggregates of grains, having porosities of about 90%. The energy needed for grain separation was 15-30x lower than the energy of vaporization. The relative abundances of Na, Mg, and Fe were nearly chondritic.

- Pomocí dvoustaničních video a fotografických pozorování šesti slabých a jedné jasné Drakonidy jsme změřili tvary, výšky, světelné křivky a atmosférická brždění meteorů. pro jasný meteor jsme získali také spektrum. Vytvořili jsme jednoduchý model ablace a fragmentace meteoroidu. Model předpokládá, že kometární meteoroidy jsou tvořeny jednotlivými zrny. Zjistili jsme, že rozsah hmotností zrn byl relativně úzký ve všech meteoroidech, ale lišil se případ od případu. Meteoroidy o rozměru několika milimetrů byly tvořeny desetitisícy až téměř milionem zrn. Meteoroidy byly porézními slepenci zrn s porézností okolo 90%. Energie potřebná k oddělení zrn byla 15-30x nižší než energie odpaření. Relativní zastoupení Na, Mg a Fe bylo přibližně chondritické. (cs)
