Bulletin

Solar activity was at very low levels. The Sun remains spotless and no flares have been observed. No Earth directed coronal mass ejections (CME) were observed over the last 24 hours in the available coronagraph imagery. The greater than 10 MeV proton flux remained at background levels over the past 24 hours. Solar activity is expected to remain at very low levels.

The solar wind speed varied between approximately 400 and 500 km/s (ACE). Bz varied between -7 and +5 nT. The interplanetary magnetic field was predominantly directed away from the Sun (positive sector). Quiet geomagnetic conditions were observed, with the Kp index (NOAA) and the local K index (Dourbes) ranging between 1-2 over the past 24 hours.

Quiet to unsettled geomagnetic conditions are expected with the possibility of isolated active conditions later today (July 15) or tomorrow (July 16), due to the arrival of the solar wind stream associated with the negative polarity equatorial coronal hole which began to transverse the central meridian on July 11.

Die heute international geschätzte Sonnenfleckenanzahl (ISN): 000, basierend auf 09 Stationen.
