As was pointed out the rhythm of AR2371 was becoming obvious with cyclic peaks of increasing outbursts (flares).
Solar windA severe G4-class geomagnetic storm is in progress on June 22nd. This follows a series of rapid-fire CME strikes to Earth's magnetic field during the past 24 hours. Magnetic fields in the wake of the latest CME are strongly coupled to Earth's own magnetic field. This is a condition that could sustain the geomagnetic storm for many hours to come. High- and mid-latitude sky watchers should be alert for auroras tonight, especially during the hours around local midnight.
speed: 633.3 km/sec - high - normally one will see a slower wind speed with a high proton count. This time it is different, high kinetic energy is hitting.
density: 13.6 protons/cm3 - high count but not as high as it could be
AR 2371 is pointed at the earth.
Here is the blast that hit earth and did cause a bit of a radio blackout.
Auroral activity is very HIGH as shown in this current graphic:

Planetary K-index
Now: Kp= 5 storm
24-hr max: Kp= 5 storm
Interplanetary Mag. Field
Btotal: 35.6 nT
Bz: 17.3 nT north - north orientation is a good thing, a strong geomagnetic interplanetary field, much higher than normal.. North is shielding.. I can only imagine if this was a southerly polarity how much energy would be coming in.. AS-IS it is pretty strong looking at the auroral oval.
