Solar activity was at low levels over the past 24 hours. There are no visible active regions. Solar activity is expected to remain at low levels.

No Earth directed Coronal Mass Ejections (CMEs) have been detected in the available coronagraphic imagery.

An equatorial positive polarity coronal hole traversed central meridian on February 3, its associated high speed solar wind is expected to arrive to the Earth in 24 to 48 hours.

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 remained below the 1000 pfu threshold during the past 24 hours. The electron flux is expected to remain below this alert level for the next period. The 24h electron fluence was mostly at normal levels, it is expected to remain so in the next 24 h.

Over the past 24 hours, the solar wind speed ranged between 480 and 410 km/s. The total magnetic field strength fluctuated between 4 and 5 nT. Bz had a minimum value of -4 nT. The interplanetary magnetic field was directed towards the Sun (negative polarity). Slow solar wind conditions expected for the next 24 hours.

Geomagnetic conditions were quiet to unsettled (NOAA Kp recorded values between 0-3, local k Dourbes between 0-3). Geomagnetic conditions are expected to be mostly quiet in the next 24 hours, and increase to active levels after that with the arrival of the high speed stream.
