Bulletin

Solar activity is on the C-level, with all the C-class flares originating from the Catania sunspot group 80 (NOAA AR 2361). The strongest flare of the past 24 hours was the C2.7 flare peaking yesterday at 15:19 UT. We expect flaring activity at the C-level, with an M-class flare possible but unlikely. A small low-latitude coronal hole in the southern hemisphere reached the solar central meridian yesterday. We expect the associated solar wind flow to arrive at the Earth late on June 7 - early on June 8. Given the small size of the coronal hole, we expect geomagnetic conditions to remain at the quiet to unsettled levels, with a stronger geomagnetic perturbation being unlikely. The Earth is currently inside a slow (around 290 km/s) solar wind flow with average (around 4 nT) interplanetary magnetic field magnitude. The geomagnetic conditions are quiet and are expected to remain so in the next 48 hours.

Today's estimated international sunspot number (ISN): 069, based on 22 stations.
