Bulletin

Solar activity was low with X-ray flux remaining below C Level. All the regions on the visible disk are fairly simple, NOAA AR 2558 can produce C-class flares. No Earth directed CMEs have been recorded in coronagraph data.

Solar wind speed is at 450 km/s. The interplanetary magnetic field intensity at 4 nT. Geomagnetic conditions were quiet to unsettled. The same situation is expected to continue today and active conditions are expected from June 21 (late) onwards due to a high speed stream from a coronal hole.

Today's estimated international sunspot number (ISN): 034, based on 11 stations.
