Description:

We report on simultaneous profiles measurements obtained in the La, Lp, MglI and Call lines in a sunspot umbra and penumbra, performed with the L. P. S. P. instrument on OSO 8. Although the statistic does not allow for a full time coverage in all lines, we are able to analyze CalI H and K shifts and intensity variations, along with calibrated average profiles in other lines. Results are compared with other observations and predictions of the acoustic model.
