Difficulties in the interpretation of the meteor phenomenon have been mainly caused by the impossibility of dividing in time and space the information obtained from the observations. To a certain extent the use of the method of instantaneous exposures can help to overcome these difficulties. The present paper deals with the study of a bright meteor N 770533, broken into many fragments and its spectrum, which was doubly photographed in 1977, July, 19h 30m 56s UT in Dushanbe (Figure 1). The photographs were taken by the method of instantaneous exposures, which has been described by Babadzhanov and Kramer (1968). To take the photographs of spectra, transparent replica diffraction gratings with light concentration in the first order have been used. Rotating shutters made it possible to obtain meteor images in integrated light with duration of 0.00056s every 0.02s, as well as to obtain spectra with durations of 0.00056s and 0.0033s every 0.02s. A panchromatic emulsion with spectral sensitivity 3800 to 7000 Å was used.
