The solar activity remained at very low levels with no significant solar flares over the past 24 hours. The visible sunspot region (Catania 37, N0AA-AR 2767) remained stable with classification alpha/Hsx. The X-ray flux is observed below B-class level and the solar activity is expected to remain at low levels over the next 24 hours.

No Earth directed Coronal Mass Ejections (CMEs) were observed in the available coronagraph imagery.

The greater than 10 MeV proton flux was at background 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 at background to moderate levels over the past 24 hours and is expected to remain so in the next 24 hours.

The solar wind parameters (ACE and DSCOVR) were at slightly enhanced levels over the past 24 hours. The total interplanetary magnetic field was weak with values of 2-5 nT. The north-south Bz component varied weakly between -4 nT and 3 nT. The solar wind speed fluctuated around 380 km/s with a gradual increase to 420 km/s at 07:30 UTC today. In the past 24 hours the Phi angle remained negative over the entire period, suggesting the arrival of a HSS from the negative polarity equatorial coronal hole which crossed the central meridian on July 23rd. The solar wind conditions are expected to remain slightly enhanced for the next day under the remaining influence of the HSS, originating from the equatorial coronal hole facing the Earth at the end of last week.

The geomagnetic conditions were mostly quiet with a maximum Kp-NOAA value equal to 1 and an isolated local unsettled period where K-Dourbes index reached 3 at 2pm UTC yesterday. Mostly quiet to unsettled conditions are expected for the next 24 hours due to the remaining influence of the HSS.
