Bulletin

Solar activity was very low with no flares above the B-class in the past 24 hours. An isolated C-class flare remains possible but unlikely. The Earth is currently inside a fast (around 620 km/s) solar wind flow produced by either of the low-latitude coronal holes that reached the solar central meridian on June 12. The Kp index reported by NOAA reached 6 yesterday evening in response to the arrival of the interaction region between the fast solar wind and the preceding slow wind flow. Dourbes and IZMIRAN reported K = 5. Currently the geomagnetic conditions are unsettled (NOAA, Dourbes) to active (IZMIRAN). Further geomagnetic storming (probably up to K = 5 level) remains possible.

Today's estimated international sunspot number (ISN): 041, based on 21 stations.
