From the video description:
An earth-facing M1.1 Solar Flare was registered by Active Region 11731 at 05:10 UT this morning. This eruption took place in an earth-facing position which means any Coronal Mass Ejection (CME) will be earth directed. Latest imagery shows a strong CME leaving the sun shortly after the eruption. Geomagnetic storms should result as impact on earths magnetic field is expected sometime on May 5th. Associated with this blast was a 10cm Radio Burst and a Type II Radio Emission with an estimated velocity of 703 km/s.
