Space Weather
Space weather describes changing environmental conditions in near-Earth space. Magnetic fields, radiation, particles and matter, which have been ejected from the Sun, can interact with the Earth’s upper atmosphere and surrounding magnetic field to produce a variety of effects.

Aurora forecasts
Northern Hemisphere
There is a chance of further auroral enhancements into the UTC working week due to a fast solar wind, although this will be at high geomagnetic latitudes and less extensive compared to the past UTC weekend. There is a falling chance of visibility from the north of Scotland and similar magnetic latitudes.
Southern Hemisphere
There is a chance of further auroral enhancements into the UTC working week due to a fast solar wind, although this will be at high geomagnetic latitudes and less extensive compared to the past UTC weekend. There is a falling chance of visibility from the far south of New Zealand and similar magnetic latitudes.

Forecast overview
Space Weather Forecast Headline: Falling Slight Chance of further Minor geomagnetic storm G1. Further Minor radio blackouts (R1s) likely.
Analysis of Space Weather Activity over past 24 hours
Solar Activity: Moderate levels, with a peak flare reaching low level Moderate class at 08/1537 UTC. There are five sunspot regions on the visible disc. The most significant and magnetically complex region on the disc resides in the south near centre-disc. This spot has significant magnetic complexity and mixed polarity maintained within its central portion, with a delta formation evident where the compact central portion connects with the leading portion. The remaining regions are small and magnetically simple.
No Earth-directed Coronal Mass Ejections (CMEs) were observed in available satellite imagery.
Solar Wind / Geomagnetic Activity: Solar winds were reflective of an ongoing fast wind. The solar wind speed was Strong throughout. The Interplanetary Magnetic Field was weak throughout. The north-south component was erratic and weak. Geomagnetic activity was Quiet to Active (Kp2-4).
Energetic Particles / Solar Radiation: No solar radiation storms were observed.
Four-Day Space Weather Forecast Summary
Solar Activity: Moderate activity is likely, with occasional low-level moderate-class flares from the largest sunspot region likely to continue. There is a daily slight chance of these flares reaching strong-class.
Solar Wind / Geomagnetic Activity: There are no Earth-directed coronal mass ejections, and the only forecast feature is therefore the current Strong coronal hole fast wind, which should now gradually wane through the period.
Quiet to Active (Kp2-4) geomagnetic activity is most likely, with a falling Slight Chance of further G1 minor geomagnetic storms on Days 1 and 2 (09-10 Nov) while the solar wind speed is Strong and there is a risk of geomagnetic sub-storms. Mainly Quiet (Kp0-2) conditions should prevail Day 3-4 (11-12 Nov).
Energetic Particles / Solar Radiation: There is a rising slight chance of exceeding the S1/Minor Radiation Storm threshold, should the most complex active region produce any larger x-ray flares as it rotates westwards.

Solar imagery
SDO AIA-193
This channel highlights the outer atmosphere of the Sun - called the corona - as well as hot flare plasma. Hot active regions, solar flares, and coronal mass ejections will appear bright here. The dark areas - called coronal holes - are places where very little radiation is emitted, yet are the main source of solar wind particles.

SDO AIA-304
This channel is especially good at showing areas where cooler dense plumes of plasma (filaments and prominences) are located above the visible surface of the Sun. Many of these features either can't be seen or appear as dark lines in the other channels. The bright areas show places where the plasma has a high density.
