Here is the current forecast discussion on space weather and geophysical activity, issued 2017 Mar 30 1230 UTC.

Solar Activity

24 hr Summary: Solar activity was very low. Region 2644 (N12W16, Eao/beta) exhibited slight decay and remained stable. Region 2645 (S10E23, Dsi/beta) grew slightly, showing consolidation between the intermediate spots and the leader spots, as well as some of the intermediate spots and trailer spots. Region 2646 (N06W90, plage) lost its spot as it rotated past the western limb. No Earth-directed CMEs were observed in available satellite imagery.

Forecast: Solar activity is expected to be very low, with a chance for C-class flares and a slight chance for M-class flares (R1-R2 Minor-Moderate) during the forecast period (30 Mar-1 Apr). Region 2644 continues to weaken and stabilize, while Region 2645 continues to exhibit growth and intermediate spot generation.

Energetic Particle

24 hr Summary: The greater than 2 MeV electron flux was at high levels for the majority of the period, reaching a peak flux value of 29,502 pfu at 29/1500 UTC. The greater than 10 MeV proton flux remained at background values.

Forecast: The greater than 2 MeV electron flux is expected to be at mostly high levels all three days (30 Mar-1 Apr) with a chance for very high levels on days two and three due to continuing CH HSS influences. The greater than 10 MeV proton flux is expected to continue at background levels all three days.

Solar Wind

24 hr Summary: Solar wind parameters remained enhanced as CH HSS influence persisted. Total field strength was steady between 3 to 5 nT, the Bz component was variable between -4 nT and +5 nT, and solar wind speed ranged from 600 to and 685 km/s. The phi angle was predominantly negative (towards the Sun).

Forecast: Solar wind speed is expected to remain elevated as CH HSS influence continues through day one (30 Mar). Recurrence and model data suggests conditions could enhance further as the CH HSS influence increases on days two and three (31 Mar-1 Apr).

Geospace

24 hr Summary: The geomagnetic field was at unsettled to active levels, with an isolated period of G1-Minor storming during the 30/0300-0600 synoptic period as CH HSS influences continued.

Forecast: The geomagnetic field is expected to be at primarily unsettled to active levels, with an isolated period of G1 (Minor) storming likely on day one (30 Mar), due to persistent CH HSS effects. Days two and three (31 Mar-1 Apr) are expected to be unsettled to active, with a chance for G1 storm levels, as CH HSS influences continue.
