Bulletin

NOAA AR 2371 is decaying and produced only minor C-class flares in past 24h (the strongest was a C1.7 with peak at 06:06 UT). It still has potential for M-class flares. The fast solar wind from a high latitude coronal hole in the northern hemisphere may arrive to the Earth today. Geomagnetic conditions have decreased to unsettled levels after the passage of the CME from June 22. Conditions may increase with the arrival of the CME from June 25 expected later today.

Today's estimated international sunspot number (ISN): 019, based on 18 stations.
