ocr: Another huge eruptive prominences recorded by EIT in in the resonance line of singly ionized helium (He I) at 304 Angstroms. While the filament was active at least nine hours before this exposure, the eruption started less than three hours before this image was obtained (26 August 1997 at 16:07 UT). The prominence is over 350,000 km across, large enough to span 28 Earths.
