✦ Synopsis

Observations are reported of an Ha filament clearly visible in the image of the chromosphere at the limb as well as in the Hc~ spectrum of the same part of the chromosphere. Observations of this kind may give valuable information about the absorption mechanism at work in filaments.

Time succession of 25 Ha spicules has been studied. The spectra are obtained at a height of 6 arc sec during 21 rain (38 pictures) with the 53 cm Lyot coronagraph. Total intensities W, widths AA and radial velocities Vr are determined (about 650 Ha line profiles). For 14 spicules the sign of V, vari
