Solar activity was very low over the past 24 hours. No significant flares have been recorded. The solar disk is currently spotless. Solar activity is expected to be very low over the next 24 hours.

No Earth-directed Coronal Mass Ejections (CMEs) have been detected in the available coronagraphic 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 remained below the 1000 pfu alert threshold and is expected to remain below this level during the next 24 hours. The 24h electron fluence was at nominal levels and is expected to remain so.

The solar wind speed has been slightly enhanced with values between 390 to 500 km/s over the past 24 hours. The Bz component was mostly positive, fluctuating between -4 and +6 nT. The interplanetary magnetic field phi angle was predominantly in the positive sector (directed away from the Sun). The solar wind speed and interplanetary magnetic field are expected to continue to be enhanced on May 04, due to the ongoing influence of the high-speed stream associated with the positive polarity coronal hole in the southern hemisphere, which crossed the central meridian on April 30.

Geomagnetic conditions were quiet (NOAA Kp and local K Dourbes 1-2) over the past 24 hours. Geomagnetic conditions are expected to be quiet to unsettled over the next 24 hours, with possible isolated active periods due to the influence of the high-speed stream.
