Space Weather Forecast Headline: Chance of isolated Moderate class flares.

Analysis of Space Weather Activity over past 24 hours

Solar Activity: Solar activity has remained at Low Levels with only isolated Common class flares observed, although one flare did come close to becoming Moderate, this was from a previously active region which has now rotated off behind the northwest limb. There are six sunspot regions on the visible disc, of which two are unnumbered, small, weak and magnetically simple. A region in the northwest remains the largest and most complex of the numbered regions. The remaining numbered regions are smaller and either unipolar or bipolar, and generally stable and inactive.

There were no Earth-directed Coronal Mass Ejections (CMEs) observed over the past 24hrs.

Solar Wind / Geomagnetic Activity: Solar wind speeds have persisted at Slightly Elevated levels whilst slowly declining, and are currently around 410 km/s. The strength of the solar winds magnetic field was Weak, while the north-south component was Weak and variable. As a result the geomagnetic activity was Quiet.

Energetic Particles / Solar Radiation: GOES18 high energy (>10 MeV) proton flux was at or near Background. 

Four-Day Space Weather Forecast Summary

Solar Activity: Low solar activity is expected to continue, though there is a chance of isolated Moderate-class flares. The chance of significant flares may increase, as new or returning regions are likely to rotate onto the visible disc through the period.

Solar Wind / Geomagnetic Activity: No Earth-directed CMEs feature in the forecast. Solar wind speeds are expected to continue declining to reach Background levels through Day 1 (22 May). No significant enhancements are anticipated over the following days.

Geomagnetic activity is expected to remain predominantly Quiet with a chance of isolated Unsettled intervals.

Energetic Particles / Solar Radiation: GOES >10 MeV proton flux is expected to remain at background levels.
