Bulletin

Solar activity has increased since the last bulletin. More than a dozen C-class flares and one M1.0 flare were observed by the GOES spacecraft. Almost every currently visible sunspot group contributed to this activity. The M1.0 flare, peaking at 8:55 UT on June 11 originated from a region that is currently turning to the Earth-facing side of the Sun. More flaring activity is to be expected, certainly at the C-level. Also an additional M-class flare is possible, mainly from the new region at the East limb (no NOAA number yet). The latest coronagraphic images indicate the occurrence of a CME propagating east of the Sun-Earth line, but more complete data are needed to analyse this.

The effects of the high speed stream are gradually decreasing. The solar wind speed is currently around 570 km/s and the interplanetary magnetic field magnitude obtains values below 5 nT. Geomagnetic conditions remain quiet to unsettled (K= 1 to 3), which is expected to continue for the next few hours. Geomagnetic activity might reach active to at most minor storm levels on June 12, depending on the potential arrival of the June 9 CME and the magnetic field properties.
