X1.2 solar flare with earth-directed CME

Sunspot region 4274 is at it again with a long duration X1.2 solar flare (R3-strong) that peaked at 09:20 UTC this morning. Solar imagery from SDO shows its an eruptive event along with associated Type II and IV radio sweeps and a coronal mass ejection was launched into space. Considering the location of this sunspot region near the center of the solar disk, the resulting coronal mass ejection is very likely to have an earth-directed component. We also entered a S1 minor solar radiation storm following the X1.2 flare which degrades HF radio signals at high latitudes.
