Here is the current forecast discussion on space weather and geophysical activity, issued 2017 Mar 01 1230 UTC.

Solar Activity

24 hr Summary: Solar activity was very low. There were three spotted regions on the visible disk. Region 2640 (N08W10, Axx/alpha) lost its trailing spots, Region 2638 (N16W49, Hsx/alpha) remained stable and mostly unchanged in appearance, and Region 2641 (N15E20, Cao/beta) developed additional leading spots. No Earth-directed CMEs were observed in available satellite imagery.

Forecast: Solar activity is expected to remain at very low levels with a chance for C-class flare activity over the next three days (01-03 Mar).

Energetic Particle

24 hr Summary: The greater than 2 MeV electron flux was at normal to moderate levels. 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 for the next two days (01-02 Mar), with a chance of reaching high levels on day two (02 Mar), due to CH HSS influences. By day three (03 Mar), moderate to high levels are likely due to ongoing CH HSS effects. The greater than 10 MeV proton flux is expected to persist at background levels throughout the forecast period.

Solar Wind

24 hr Summary: Solar wind parameters were at nominal levels before becoming enhanced late in the period with the passage of a CIR ahead of a negative polarity, polar-connected CH HSS. Total field strength was elevated between 9 and 20 nT while the Bz component oscillated between +10 and -17 nT. Solar wind began the period around 425 km/s and increased to over 550 km/s by the end of the period. The phi angle was negative.

Forecast: The solar wind environment is expected to remain enhanced on days one through three (01-03 Mar) due to the effects of the CH HSS. Solar wind speeds ranging from 600 - 700 km/s are anticipated based on earlier observations from STEREO-A.

Geospace

24 hr Summary: The geomagnetic field was at quiet to unsettled levels until late in the period (01/1036 UTC) when G1-Minor storm levels were observed.

Forecast: Unsettled to active conditions, with isolated G1 (minor) geomagnetic storming periods, are expected on days one and two (01-02 Mar) as a negative polarity CH HSS becomes geoeffective. Mainly unsettled to active levels are anticipated on day three (03 Mar) as the CH HSS begins to subside.
