Bulletin

The Sun is spotless and produced only a few A flares in the past 24 hours, from a new region near the East limb. The chance for a C flare in the next 24 hours is estimated at 5%.

No Earth-directed Coronal Mass Ejections (CMEs) were observed in available coronagraphic imagery.

The greater than 10 MeV proton flux was at nominal levels in the past 24 hours, and is expected to stay at nominal levels in the next 24 hours.

Solar wind speed as registered by DSCOVR further decreased from about 370 to 315 km/s. The Interplanetary Magnetic Field (IMF) was oriented towards the Sun and its magnitude varied between about 3 and 5 nT. Bz was never below -5 nT. The solar wind is expected to stay at nominal levels in the next days.

Quiet to unsettled geomagnetic conditions (K Dourbes between 1 and 3; NOAA Kp between 1 and 2) were registered in the past 24 hours. Quiet to unsettled conditions (K Dourbes < 4) are expected on July 29, 30 and 31.

Die heute international geschätzte Sonnenfleckenanzahl (ISN): 000, basierend auf 20 Stationen.
