Bulletin

There are presently no active regions on the visible side of the Sun, and accordingly solar activity is low (without C-class flares reported). We expect low solar activity to persist in the coming hours. The CME, first seen in the SOHO/LASCO C2 field of view at about 14:24 UT on October 1, was associated with the EUV wave and coronal dimming. The bulk of the CME mass was in the north-east direction, and the CME had angular width of about 90 degrees and projected speed of 400 km/s (as reported by the CACTus software package). This CME will not arrive at the Earth.

The solar wind speed is slowly decreasing and it is presently about 500 km/s. The interplanetary magnetic field magnitude is stable having value of about 5 nT. Due to the long interval of the negative value of the Bz component of the interplanetary magnetic field and the fast solar wind, active geomagnetic conditions were reported (around 23:40 UT) on October 1. The local station at Dourbes reported K=4, and NOAA reported Kp=4. We expect quiet to unsettled geomagnetic conditions in the coming hours.

Die heute international geschätzte Sonnenfleckenanzahl (ISN): 008, basierend auf 17 Stationen.
