Abstract

We present non-LTE diagnostics of the filament observed by SOHO/SUMER on May 27, 2005 in the whole Lyman series. The filament was situated close to the disk center. The Lα observations were carried out with normal voltage of detector A. The slit was placed at the central part of the detector – outside the Lα attenuator. Therefore, the observed profiles of this line could be calibrated reliably.
