Beside the number of sunspots on the solar disc facing Earth, the solar flaring activity was at low levels. Several C-class flares were observed from different sunspot groups. The larger ones were a C5.0-class from Catania sunspot group 45 (NOAA active region 3030) at 01:34 UTC, and a C5.7-class from Catania sunspot group 53 (NOAA active region 3038) at 06:18 UTC.

No Earth-directed Coronal Mass Ejections (CMEs) have been detected in the available coronagraph images over the past 24 hours.

The greater than 10 MeV proton flux was at nominal levels over the past 24 hours and is expected to remain so for the next 24 hours. The greater than 2 MeV electron flux exceeded the 1000 pfu alert threshold in response to the high solar wind speed associated with the Coronal Hole in the past days. It is expected to remain so during the next 24 hours. The electron fluence was at moderate levels and is expected to remain so.

The solar wind parameters in Earth environment continued to be elevated due to the influence of the fast solar wind speed streams associated with the equatorial coronal hole (positive polarity) that reached the central meridian last week. The solar wind speed ranged between 471 km/s and 629 km/s. The interplanetary magnetic field magnitude showed values between 1.5 nT and 10.0 nT. The Bz component of the interplanetary magnetic field was predominantly negative and fluctuated between -5.4 nT and 6.1 nT. The enhanced solar wind conditions are expected to persist as long as Earth remains under the influence of the solar wind associated with the coronal hole.

The geomagnetic conditions were quiet to unsettle due to the elevated the solar wind conditions (NOAA Kp and local K-Belgium 1-3). The geomagnetic conditions are expected to be quiet with periods of unsettled condition as long as Earth remains under the influence of the solar wind associated with the coronal hole.
