Description	Studovali jsme vlastnosti plazmy rozsáhlého EUV filamentu pozorovaného přístroji na družici SoHO 15. října 1999. 3D strukturu EUV rozšíření (části viditelné jenom v EUV oblasti spektra) tohoto filamentu byla zreprodukovaná použitím pozorování EUV koronálních čar provedených přístrojem SoHO/CDS. Potom jsme fitovali syntetickými pozorované profily Lymanových čar vodíka, které byly pozorovány přístrojem SoHO/SUMER. Syntetické profily byly vypočteny použitím non-LTE modelu s filamentem aproximovaným jednorozměrnou vrstvou. Fitovali jsme profily z nejtmavší časti EUV filamentu (t.j. H_alpha filament) viditelné taky v H_alpha čáře i profily z EUV rozšíření tohoto filamentu. (cs) We study physical properties of plasma of the extended EUV filament observed by SoHO on October 15, 1999. 3D structure of the EUV extension (part visible in the EUV spectral range only) of this filament was reproduced using observations of the EUV coronal lines made by SoHO/CDS. Then we fitted by synthetic the profiles of hydrogen Lyman lines observed by SoHO/SUMER spectrograf. Synthetic profiles were calculated using non-LTE 1D-slab model. We fitted profiles both from the darkest part of the filament (so called H_alpha filament) visible also in H_alpha line and from its EUV extension.
