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
No enhancements to the aurora are forecast through this period. Any visibility will be restricted to just the highest geomagnetic latitudes.
Southern Hemisphere
No enhancements to the aurora are forecast through this period. Any visibility will be restricted to just the highest geomagnetic latitudes.

Forecast overview
Space Weather Forecast Headline: Chance of Moderate class flares.
Analysis of Space Weather Activity over past 24 hours
Solar Activity: Low with C-class flares, peaking at 10/1328 UTC. There are seven regions on the visible disc. The large region in the southwest has continued the trend of magnetic simplification, along with a reduction in area, while also spreading slightly through its maturation, but does maintain at least one weak, but inherently unstable, mixed polarity spot. The other regions are smaller and simple spots.
No Earth-directed Coronal Mass Ejections (CMEs) were observed.
Solar Wind / Geomagnetic Activity: Solar winds were reflective of waning fast winds from a large coronal hole. Solar wind speed fell gradually from Strong levels to current Elevated levels. Interplanetary Magnetic Field was Weak throughout. The north-south component was largely positive and also Weak. Geomagnetic activity was Quiet to Unsettled (Kp1-3).
Energetic Particles / Solar Radiation: No solar radiation storms were observed, with the count rate of energetic particles (high energy protons) persisting at Background.
Four-Day Space Weather Forecast Summary
Solar Activity: Low activity is likely, with a chance of rising to Moderate with any M-class flares, most likely from the larger region in the southwest.
Solar Wind / Geomagnetic Activity: There are no Earth-directed CMEs. Ongoing fast winds are expected to gradually ease through the period. Mainly Quiet geomagnetic activity with Unsettled intervals is forecast (Kp1-3), along with a slight chance of Active (Kp4) intervals, mainly Day 1(11 Nov)
Energetic Particles / Solar Radiation: Solar radiation storms are currently not expected. However any significant solar flares from the large region in the southwest, could result in the observed count rate of energetic particles (high energy protons) increasing. This will bring the slight chance of exceeding the S1 Minor radiation storm level.

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.
