Bulletin

The X-ray background radiation has decreased slightly. C-flaring activity is however still very likely. A forward shock is seen in ACE solar wind data around 12UT on December 13: temperature, density and magnetic field strength increased, the speed increased from around 270 km/s to 330 km/s. The shock is probably linked to the interaction of a slow and fast solar wind stream giving rise to a co-rotating interaction region. The northern coronal hole that reached the central meridian on December 10 is responsible for the fast solar wind. The planetary K index became 4 during one 3-hour interval this morning, December 14. The total magnetic field strength at the L1 point is around 10 nT, the wind carries 10 particles per cm3 at a speed of around 400 km/s. Active conditions are possible.

Die heute international geschätzte Sonnenfleckenanzahl (ISN): 094, basierend auf 11 Stationen.
