Currently, quiet conditions persist but these are unlikely to last with the recent flaring. The last storm rose to G3 levels which are indicated by a Kp index of 7: (originally At such levels, auroras were visible well into the contiguous 48 states of the United States.

These flares have all originated from Active Region 1429 which will likely produce many more such flares before it either fades out or is rotated onto the far side of the Sun.
