Mercury Bound CME in LASCO/C2

A Prominence Eruption Sends a CME to Mercury

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.

Beautiful Eruptions from the East Limb of the Sun

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).
