On April 22, 2012, filament material uncurled as an erupting prominence around sunspot group AR11463. There was a C1.8 solar flare and the resulting eruption produced a SCORE-C CME detected by SOHO/LASCO C2 at 15:30 UT.
An eruption of plasma from just behind the solar limb observed by SDO with the 304 Angstrom camera.This shows material at temperatures around 60,000-80,000 Kelvin. This produced a CME that went out the left side (East) of the Sun starting around 2 UT. At ~1000 km/s the CME has a SCORE O (for ordinary). NASA produced a computer model predicting the CME will impact STEREO Behind on 4/17 at 7:40 UT (but not Earth).
