Here is the current forecast discussion on space weather and geophysical activity, issued 2016 Apr 09 1230 UTC.

Solar Activity

24 hr Summary: Solar activity was low due to weak C-class flare activity from Region 2529 (N10E60, Ehi/beta). Over the past 24 hours, the region more than doubled in size but maintained a simple bi-pole magnetic configuration. Region 2528 (N07W73, Bxo/beta) continued to decay as it approached the west limb. Multiple filament eruptions were observed throughout the period but no Earth-directed CMEs were observed in available coronagraph imagery. Forecast: Solar activity is likely to be low with C-class flares over the next three days (09-11 Apr) due to the flare potential of Region 2529.

Energetic Particle

24 hr Summary: The greater than 2 MeV electron flux was at normal levels and the greater than 10 MeV proton flux was at background levels throughout the period.

Forecast: The greater than 2 MeV electron flux is expected to be at normal to moderate levels over the next three days (09-10 Apr). The greater than 10 MeV proton flux is expected to remain at background levels throughout the forecast period.

Solar Wind

24 hr Summary: Solar wind parameters reflected a near-background solar wind environment. Solar wind speeds gradually decreased from initial values of 360 km/s to end-of-period values approaching 330 km/s. Bt ranged between 3-7 nT. The Bz component was mostly northward to +6 nT with a few brief southward incursions to -3 nT. The phi angle configuration was highly variable throughout the period between a positive and negative sector orientation.

Forecast: Solar wind parameters are expected to be at near-background levels over the next three days (09-11 Apr).

Geospace

24 hr Summary: The geomagnetic field was quiet at all latitudes.

Forecast: The geomagnetic field is expected to be quiet all three days of the forecast period (09-11 Apr) under a nominal solar wind regime.
