There are five active regions visible on the solar disc, all of them with simple alpha or beta magnetic field configuration. Several C-class flares were detected in the last 24 hours. The strongest one was a C3.1 flare from NOAA AR 3207, peaking at 16:16 UTC. Further C class flaring is expected.

No Earth-directed coronal mass ejections (CMEs) were detected in the available coronagraph imagery over the past 24 hours.

The greater than 10 MeV proton flux was at nominal levels in the past 24 hours and is expected to remain so in the next 24 hours. The greater than 2 MeV electron flux has been below the 1000 pfu threshold and is expected to remain so. The 24h electron fluence was at normal levels and is expected to remain so over the next 24 hours.

A small equatorial coronal hole of negative polarity is expected to influence solar wind conditions within 24 hours.

The solar wind speed at the Earth decreased to 350 km/s. The magnitude of the interplanetary magnetic field is around 4 nT. The interplanetary magnetic field has a negative polarity (towards the Sun). The arrival of the high speed stream (HSS) from the equatorial coronal is expected today, although the coronal hole is small and it may not create a significant HSS.

Geomagnetic conditions were mostly unsettled both locally and at planetary levels (K_BEL and Kp up to 3). Unsettled to active conditions can be expected for the next 24 hours.
