Propagation of velocity waves are investigated in the solar chromosphere, with a special view to high frequencies (periods --->60 s). Four line profiles have been observed during 27 mn with the Sacramento Peak vacuum telescope (Ha, 3933, 8498 and 8542 Can). Three Fourier analysis are performed accor

In order to precise previous results about wave propagation in the quiet chromosphere (N. Mein and P. Mein, 1976), we study the behaviour of Doppler shifts and intensity fluctuations in 3 lines of Ca II. We use the same observation as in our previous work, that is to say a sequence of spectra lasti

Spectra of Hc~, lift and HO have been taken under good seeing conditions with the vacuum tower telescope of Sacramento Peak Observatory. Intensity curves are given at various wavelengths in these lines to permit further comparison with a tlaeoretical model. Moreover, considering in each case the ran

A high resolution profile of the solar OI 1304.9 A line has been measured from rocket spectrograms. The profile is nearly flat-topped, showing only a slight solar reversal after instrument effects and absorption due to atomic oxygen in the earth's atmosphere have been allowed for. A theoretical anal
