Here is the current forecast discussion on space weather and geophysical activity, issued 2019 May 26 1230 UTC.

Solar Activity

24 hr Summary: Solar activity remained very low with a spotless visible disk. No Earth-directed CMEs were observed in available satellite imagery.

Forecast: Solar activity is expected to remain at very low levels on 26-28 May.

Energetic Particle

24 hr Summary: The greater than 2 MeV electron flux was at normal to moderate levels while 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 26-28 May. The greater than 10 MeV proton flux is expected to continue at background levels.

Solar Wind

24 hr Summary: Solar wind parameters continued near nominal levels. Total field strength peaked at 5 nT while the Bz component varied between +4 to -2 nT. Solar wind speeds ranged from about 300-350 km/s. Phi angle was variable between sectors.

Forecast: Ambient conditions are expected on 26-27 May. Enhancements in the solar wind are forecasted on 28 May as a recurrent, negative polarity CH HSS moves into a geoeffective position.

Geospace

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

Forecast: The geomagnetic field is expected to remain at quiet levels on 26-27 May. By 28 May, field conditions are expected to increase to unsettled to active levels due to the anticipated influence of a recurrent, negative polarity CH HSS.
