Here is the current forecast discussion on space weather and geophysical activity, issued 2019 Apr 30 1230 UTC.

Solar Activity

24 hr Summary: Solar activity was at very low levels under a spotless solar disk. No Earth-directed CMEs were observed in available coronagraph imagery.

Forecast: Solar activity is expected to be very low for 30 Apr-02 May.

Energetic Particle

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

Forecast: The greater than 2 MeV electron flux is expected to be at normal to moderate levels on 30 Apr-02 May. The greater than 10 MeV proton flux is expected to continue at background levels.

Solar Wind

24 hr Summary: Solar wind parameters continued at nominal levels with solar wind speed ranging from 300-390 km/s. Total field ranged from 3-5 nT while the Bz component was between +2/-5 nT. Phi angle was oriented in a negative (towards) solar sector.

Forecast: Solar wind parameters are expected to become enhanced late on 01 May as a negative polarity CH HSS moves into geoeffective position. Solar wind speed reaching 500 km/s is likely based on STEREO A data.

Geospace

24 hr Summary: The geomagnetic field was quiet.

Forecast: The geomagnetic field is expected to be mostly quiet on 30 Apr. Late on 01 May, a negative polarity CH HSS is expected to become geoeffective causing unsettled to active conditions. Unsettled to active levels are expected to persist into 02 May.
