Abstract
Five spicule film sequences taken on different dates in Ha were studied. Maximum heights of spicules ranged downward from 20,000 km. Lifetimes ranged from the film limit of 0� 3 min to about 30 min. Distributions of maximum heights and lifetimes indicated the occurrence of numerous small, short-lived spicules that were not resolved in these films.Keywords
