Solar activity was at low levels over the past 24 hours with only one sunspot on the visible solar disc. The Catania sunspot group 83 (NOAA- AR 2812) slightly grew but did not produce any flare. Solar activity is expected to remain at low levels.

No Earth-directed coronal mass ejections (CMEs) was observed in the available coronagraph imagery.

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 the 1000 pfu threshold in the past 24 hours and is expected to remain so during the next 24 hours. The 24h electron fluence is at normal levels in the last 24 hours and is expected to stay at normal levels for the next 24 hours.

The Earth is currently in the slow solar wind regime. The solar wind parameters (ACE and DSCOVR) were at nominal levels over the past 24 hours: The solar wind speed ranged between 310 km/s and 350 km/s . The interplanetary magnetic field magnitude was below 6 nT, and Bz component varied between -3 nT and 4 nT. Slight enhancement due to the high-speed stream associated with the small patchy equatorial coronal holes (in the south hemisphere, with negative polarity) is possible but not very likely.

Geomagnetic conditions were quiet (Kp and K-Dourbes: 0-2). Quiet conditions are expected with possible short period of unsettled conditions due to possible slight enhancement of the solar wind.
