Today there is no strong flares and magnetic storms . There is only one active areas (AR) - I already told about AR here - https://steemit.com/science/@maksina/space-weather-glossary-a-active-region-ar
But due to a coronal mass ejection (CME) left the sun on June 28th we are witing some storm tomorrow. This CME is expected to reach Earth on July 2nd ( see video) .

NOAA forecasters estimate a 45% chance of G1-class geomagnetic storms when the CME arrives. High latitude sky watchers should be alert for auroras, especially in the southern hemisphere where winter darkness favors visibility.
Last auroras June , 25 under Canada ( from here )
