Multiple Earth-directed CMEs, significant geomagnetic storming possible

Solar activity was at very high levels over the past 24 hours, with a series of moderate to strong solar flares, including an M9.9 flare on July 28 with an Earth-directed component. This, coupled with the cannibal CME expected to arrive late on July 29 into July 30, suggests significant geomagnetic storming is possible, potentially in the range of G3 – Strong or even G4 – Severe on July 30.
