M6.3 solar flare and Earth directed CME
Following the appearance of a new active sunspot AR1429 on March 2, it erupted on March 5 with a major X1-class flare, sending a storm of plasma and charged particles towards the Earth, followed by a second major X5.4 -class flare on March 7. The widely-reported CME produced by this X5.4 -flare from sunspot AR1429 hit our planet’s magnetic field on March 8th. The impact was weaker than expected, producing only a mild geomagnetic storm. Power grids and other sun-sensitive technologies were unaffected.

CME Impact and G3 Class Geomagnetic Storm In Progress.
A G3 Geomagnetic Storm (KP=7) is now in progress. Solar Wind speeds touched 830km/s on the arrival of the coronal mass ejection (CME) late yesterday.
Active Region 11429 has continued where it left off, by blasting another M flare today (M6.3) while in an earth facing position, a coronal mass ejection immediately followed and is headed earths way.
Impact is expected during March 11 and another geomagnetic storm may result.
Active sunspot AR1429 continues to grow. It is now more than seven times wider than Earth, which makes it an easy target for backyard solar telescopes.
The behemoth spot has unleashed four strong flares since it emerged on March 2nd, including the X5-class eruption of March 7th. More could be in the offing. The active region has a “beta-gamma-delta” class magnetic field that harbors energy for additional X-class eruptions.
