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

Analysis of Space Weather Activity over past 24 hours

Solar Activity: Solar activity has been Low in the last 24 hours, with no significant flares observed.

There are currently six regions on the visible disc. The largest sunspot region resides in the northwest quadrant, comprising a moderately large leader with a clustering of peripheral minor spots to the south and east, one of which is of opposite polarity and connected to the large leader, resulting in a weak delta configuration. The remaining regions are relatively simple, smaller and stable.

Two slow coronal mass ejections were detected on 03 Aug, associated with filament eruptions to the north and south of centre disk, though after analysis both are expected to miss Earth, arriving at 1AU above and behind Earth on 07 or 08 Aug.

Solar Wind / Geomagnetic Activity:  Solar wind parameters were indicative of residual coronal mass ejection effects. Wind speeds were background to slightly elevated. Interplanetary Magnetic Field was mostly Moderate, though fell to consistently Weak after 04/0833 UTC. The north-south component was initially positive (northward) until 03/1530UTC, then became negative (southward) thereafter. Geomagnetic activity was Quiet to Active (Kp 2-4).

Energetic Particles / Solar Radiation: The high energy proton flux was at background levels with no radiation storms observed.

Four-Day Space Weather Forecast Summary

Solar Activity: Low solar activity is expected to continue with a slight chance of isolated Moderate-class flares.

Solar Wind / Geomagnetic Activity:  In the absence of any geoeffective coronal holes or Earth directed coronal mass ejections, solar wind speeds are expected to remain at background. Geomagnetic activity is likely to remain Quiet to Unsettled (Kp0-3). 

Energetic Particles / Solar Radiation: Proton flux is expected to continue at Background with no solar radiation storms expected.
