Solar activity was at low levels over the past 24 hours. The sunspot (Catania 83, NOAA-AR 2812) did not produce any significant flare (above B-class). 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.

Over the past 24 hours the solar wind parameters (ACE and DSCOVR) showed mostly nominal values: The solar wind speed decreased from 400 to 320 km/s . The interplanetary magnetic field magnitude was below 5 nT, and Bz component varied between -3 nT and 3 nT. The interplanetary magnetic field phi angle had a mostly negative polarity (towards the Sun). 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). Mostly quiet geomagnetic conditions are expected for the next 24 hours.
