Solar flaring activity was at moderate levels over the past 24 hours. The largest flare was a M2.4-class flare located in the NOAA Active region 3293 that rotated over the East limb. The most magnetically complex region produced C-class flare. The flaring activity is expected to remain moderate with small chance of X-class flare.

Few coronal mass ejections and flows were observed in the available SOHO/LASCO coronagraph imagery and automatically detected by the Cactus tool over the past 24 hours. However, no clear Earth-directed coronal mass ejections were identified.

The greater than 10 MeV proton flux was at the background levels over the past 24 hours. The proton flux is expected to be at the background levels over the next day. The greater than 2 MeV electron flux was above the 1000 pfu threshold due to the enhanced solar wind condition and is expected to remain at that level over the next days. The 24-hour electron fluence was at moderate levels and is expected to remind at moderate levels over the next 24 hours.

The influence of the solar wind streams associated to the negative polarity coronal hole reminds low. The solar wind speed ranged between 450 km/s and 560 km/s. The total interplanetary magnetic showed the values below 5.6 nT, and the southward interplanetary magnetic component, Bz, fluctuated between -3.9 nT and 4.4 nT. The solar wind conditions near Earth is expected to remain elevated for the next 1-2 days. The solar wind parameters are expected to remain stable for the next 24 hours.

Geomagnetic conditions were globally quiet with unsettle conditions (NOAA- Kp 1 to 3, K-BEL 1 to 3), during the last 24 hours. For the next 24 hours, they are expected to remain mainly quiet.
