Abstract

We present, for the first time, a quasi-simultaneous spectroscopic observation of the whole Lyman series of HI and continuum in a quiescent prominence. Namely we have extended our previous study of higher Lyman lines to lower members of the series, particularly L-alpha and L-beta. For the latter two lines, we compare our calibrated profiles (free of geocoronal absorption) with previous data from OSO-8 LPSP spectrometer and (for L-alpha) from UVSP/SMM. We demonstrate the importance of Lyman lines for studies of the base of the prominence-corona transition region.
