Here is the current forecast discussion on space weather and geophysical activity, issued 2016 Feb 27 1230 UTC.

Solar Activity

24 hr Summary: Solar activity was at low levels. Region 2506 (S06E13, Dai/beta) produced a C3/Sf flare at 27/0555 UTC. The region underwent development, adding new intermediate and trailer spots. Region 2507 (N19W66, Bxo/beta) briefly decayed into plage but redeveloped two small spots near the end of the period. No Earth-directed CMEs were observed in available coronagraph imagery.

Forecast: Solar activity is expected to be very low with a chance for C-class flare activity throughout the forecast period (27-29 Feb).

Energetic Particles

24 hr Summary: The greater than 2 MeV electron flux was at normal to moderate levels. The greater than 10 MeV proton flux remained at background levels.

Forecast: The greater than 2 MeV electron flux is expected to be at normal to moderate levels on days one and two (27-28 Feb), decaying to normal levels by day three (29 Feb). The greater than 10 MeV proton flux is expected to remain at background levels.

Solar Wind

24 hr Summary: Solar wind parameters, as measured by the ACE satellite, reflected mostly nominal conditions. Bt was observed between 3-7 nT while the Bz component varied between -3 to +5 nT. Solar wind speeds remained relatively low, averaging around 400 km/s through the period. Phi angle was predominantly oriented in the positive sector.

Forecast: Solar wind conditions are likely to persist at mostly nominal levels on days one through three (27-29 Feb)

Geospace

24 hr Summary: The geomagnetic field was at quiet levels.

Forecast: The geomagnetic field is expected to be at predominately quiet levels all three days (27-29 Feb) under a mostly nominal solar wind regime.
