Continuous spectral observations of spicules

D₃ and H line spectrograms of spicules are analysed. The spectrograms are obtained with a specific device attached to the 53 cm coronagraph of Abastumani Astrophysical Observatory. Certain results are derived, based on the observational material consisting of 70 height series spectrograms taken over a period of 44 min in H line and 60 height series spectrograms taken over a period of 30 min in D₃. Each series involves 8 spectrograms reflecting the state of spicules at eight different heights in the chromosphere.
