The solar flaring activity was at low levels over the past 24 hours with only very few small C-class flares from several sunspots groups visible on the disc seen from Earth. We expect a very low flaring activity with a small chance of isolated C-class flares.

No clear Earth-directed Coronal Mass Ejections (CMEs) have been detected in the available coronagraph images over the past 24 hours. However, a halo CME was detected by Cactus tool (the software package for 'Computer Aided CME Tracking') on June 26, at 03:30 UTC. Its main direction was South-West. No clear signature on disc could be associated to this CME, this indicate that the CME may well be backward. However, a confirmation is needed when data comes in.

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 was below 1000 pfu alert threshold and it is expected to remain so during the next 24 hours. The electron fluence was at normal to moderate levels and is expected to remain normal to moderated levels in the next 24 hours.

The solar wind parameters in Earth environment was enhanced with the expected arrival of the fast solar wind coming from coronal holes (negative polarity): the wind speed increased from 400 km/s up to 655 km/s. The interplanetary magnetic field magnitude reached values around 13 nT. The Bz component of the interplanetary magnetic field fluctuated between 12.0 nT and 8.7 nT being predominately negative. The solar wind conditions is expected to remain enhanced as long as Earth remain under the influence of the high-speed streams from coronal holes.

The geomagnetic conditions were active (NOAA Kp 4) in response of the arrival of the high-speed streams and the prolonged negative values of the Bz component of the interplanetary magnetic field. The geomagnetic conditions are expected to be unsettle with possible periods of active conditions.
