Popis:	Chromospheric spicules are observed with high spectral and moderate spatial resolution in H alpha , H BETA , H, and K. Individual spicules seem to have much larger line widths than do quiescent prominences. All strong lines (including H and K) except D/sub 3/ change from self-reversed or flat-topped to Gaussian profiles with increasing height. D/sub 3/ has a Gaussian profile whose half-width increases with height. (auth)
