| Zusammenfassung |
| The STEREO mission has been providing stereoscopic view of the filament eruptions in EUV wavelengths. The most extended view during
filament eruptions is seen in He II 304 Å observations, as the filament spine appears darker and sharper. The projected
filament width appears differently when viewed from different angles by STEREO satellites. Here, we present a method for estimating
the width and inclination of the filament sheet using He II 304 Å observations by STEREO-A and B satellites from the two viewpoints.
The width of the filament sheet, when measured from its feet to its apex, gives estimate of filament height above the chromosphere. |
