Solar activity was at very low levels. No numbered sun spots were observed on the solar disc. No significant flares were detected in the last 24 hours and none are expected in the next 24 hours.

No Earth-directed coronal mass ejections (CMEs) were detected 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 remain so in the next 24 hours. The greater than 2MeV electron flux remained under the 1000 pfu threshold and is expected to remain so in the next 24 hours. The 24h electron fluence was at nominal levels and is expected to remain so, although slight increase is possible due to the influence of the HSS currently affecting the Earth.

Over the past 24 hours the solar wind conditions (ACE and DSCOVR) started to recover from the HSS which arrived to the Earth on Feb 6th. The total magnetic field varied between 0.8 nT an 6 nT and its Bz component weakly oscillated between -4 nT and 4 nT. The phi angle was predominantly positive reflecting the polarity of the coronal hole affecting the Earth. The solar wind speed showed a gradual decreased from 550 km/s to 410 km/s as the effect of the HSS starts to wane.

The geomagnetic conditions over the past 24 hours were predominantly quiet with several unsettled periods and two isolated locally active conditions with K Dourbes equal to 4. Mostly quiet conditions are expected in the next 24 hours as the influence of the HSS continues to wane. Isolated unsettled to active periods remain possible.
