Space Weather Forecast Headline: Chance of Moderate-class X-ray flares. 

Analysis of Space Weather Activity over past 24 hours

Solar Activity: Solar activity has been Low with only Common-class flares observed in the past 24 hours.

There are currently eleven sunspot regions on the visible disc. There are a number of regions clustered together in the southeast and southwest of the disc, but the individual regions themselves are all fairly simple, are generally stable, with little growth or development observed. Perhaps most of note is a region in the northwest, which has shown the most recent growth and development, and exhibits some magnetic complexity. The remaining spot regions are generally small and simple.

No Earth directed Coronal Mass Ejections (CME) were observed in the past 24 hours. 

Solar Wind / Geomagnetic Activity: Solar winds showed either some lingering weak coronal hole and/or CME influence. Wind speeds varied between 360 to 420km/s. The Interplanetary Magnetic Field was Weak to Moderate. The north-south component varied, mostly weakly, but becoming briefly moderate at times. Geomagnetic activity was Quiet to Unsettled (Kp1-3).

Energetic Particles / Solar Radiation: Solar radiation levels have returned to background levels after a recent solar radiation storm from a far-sided eruption. 

Four-Day Space Weather Forecast Summary

Solar Activity: Generally Low activity is expected, with a chance for isolated Moderate-class flares. 

Solar Wind / Geomagnetic Activity: No Earth-directed CMEs currently feature in the forecast. The solar wind is currently experiencing minor disturbance, due to either weak CME influence and/or lingering weak coronal hole fast wind effects. A small coronal hole in the southern hemisphere is expected to provide minor enhancements in the coming days, with wind speeds perhaps reaching up to 500 km/s, although this is low confidence. 

Quiet to Unsettled geomagnetic activity is expected at first, but activity is likely to become Unsettled to Active with coronal hole influence, most probably on Days 1-2 (28-29 May), with a slight chance of G1/Minor Storm intervals.

Energetic Particles / Solar Radiation: Solar radiation levels are declining after a recent brief enhancement due to a far side eruption. Radiation levels are most likely to remain at background levels for the rest of this period.
