On the last rotation this gave periods of minor storming (Kp=5, less intense than the occasional major storming during previous rotations) and similar effects are expected from early on Saturday Oct 28th. Solar activity is expected to remain very low, and the solar disk will be spotless once NOAA AR0917 completes its W limb transit later today. TODAY'S ESTIMATED ISN : 000, BASED ON 12 STATIONS.
