The solar activity has been very low over the past 24 hours. The region in the SE quadrant has developed a sunspot and has had low activity. The solar activity is expected to remain at low levels over the next 24 hours.

No Earth-directed coronal mass ejections were observed in the available coronagraphic imagery.

The greater than 10 MeV proton flux was at background levels in the past 24 hours, and is expected to stay at nominal levels in the next 24 hours. The greater than 2 MeV electron flux remained below the 1000 pfu alert threshold, were it is expected to remain during the next 24 hours. The 24h electron fluence was at nominal levels and is expected to remain at those levels over the next 24 hours.

The solar wind speed slightly increased from 320 to 380 km/s over the past 24 hours. The total magnetic field strength fluctuated between 2 and 7 nT. The values of the Bz component varied between -6 and +4 nT. The interplanetary magnetic field phi angle switched from the positive sector (directed away from the Sun) to the negative sector around April 10 02:20UT. Any effects from the high speed stream from the small, negative polarity coronal hole at central meridian April 8 have been minor. Over the next 24 hours, we can expect the last of its effects and return of solar wind parameters to background levels.

Geomagnetic conditions were at quiet levels (NOAA Kp and local K Dourbes 0-2) over the past 24 hours. Quiet to unsettled conditions are expected over the next 24 hours.
