The solar activity was quiet over the past 24 hours, with the X-ray flux below C-level. Two sunspot groups are visible on the visible disc (Catania sunspot group 54, NOAA AR-2880 and Catania sunspot group 58, NOAA AR-2882) and a newly emerged unipolar sunspot groups (Catania sunspot group 58). They did not show any significant flaring activities. The solar activity is expected to remain at low levels over the next 24 hours with a very small chance of C-class flare.

No Earth directed Coronal Mass Ejection (CME) has been observed in the available coronagraph 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. The greater than 2 MeV electron flux was below the 1000 pfu and at nominal levels in the past 24 hours, and is expected to stay at nominal levels in the next 24 hours. The greater than 2 MeV electron fluence was at nominal levels in the past 24 hours, and is expected to stay at nominal levels in the next 24 hours.

The Earth remained under the slow solar wind speed regime over the past 24 hours. The solar wind parameters (as observed by ACE and DSCOVR) showed an ambient background solar wind flow: The wind speed ranged from 280 km/s to 340 km/s. The interplanetary magnetic field magnitude was below 6.0 nT with its Bz components fluctuating between -5.0 nT and 4.0 nT. Since 08:00 UTC the interplanetary magnetic field parameters showed some enhancement associated with the phi angle changing from positive to negative sector: the magnitude reached up to 9.3 nT and the Bz component reached -8.2 nT. Nominal solar wind regime is expected to persist in the next 24 hours. Mostly nominal solar wind regime is expected to persist in the next 24 hours.

The geomagnetic conditions were quiet over the past 24 hours: values of K-Dourbes and NOAA-Kp index between 1 and 2 were registered. Currently unsettled conditions is observed in response to the enhanced interplanetary magnetic field. Quiet conditions with occasionally unsettled conditions are expected as long as the Earth remains in slow solar wind speed regime.
