Bulletin

Solar activity was low with two lower C-class flares. The source region was NOAA active region (AR) 2434, which is close to the west limb. NOAA AR 2436 became slightly more complex in its trailing part, while the other regions were stable. Flares at the C-level are expected. No Earth- directed CMEs were observed.

A shock was observed in the solar wind around 18:30 UT on October 24. Solar wind speed, density and temperature made a jump. The magnitude of the Interplanetary Magnetic Field (IMF) has reached a magnitude of 14 nT with a mainly positive Bz component varying from -9 to 10 nT. Solar wind speed reached 540 km/s. The shock is probably related to the October 22 CME. Geomagnetic conditions are quiet (K<3) to unsettled (K=3), which is mainly expected to continue.

Die heute international geschätzte Sonnenfleckenanzahl (ISN): 063, basierend auf 14 Stationen.
