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
Geomagnetic activity is expected to be near background levels until the arrival of fast solar winds from a coronal hole on 11 June (UTC). This is likely to slightly enhance aurora activity, with aurora potentially visible across northern parts of Scotland and similar geomagnetic latitudes, perhaps continuing on 12 June. However, short hours of darkness will limit any viewings where skies are clear.
Southern Hemisphere
Geomagnetic activity is expected to be near background levels until the arrival of fast solar winds from a coronal hole on 11 June (UTC). This is likely to slightly enhance aurora activity, with aurora potentially visible across southern parts of New Zealand and similar geomagnetic latitudes, perhaps continuing on 12 June.

Forecast overview
Space Weather Forecast Headline: Minor storms Expected day 1 (11 Jun) and Likely day 2 (12 Jun). Chance of isolated Moderate class flares throughout.
Analysis of Space Weather Activity over past 24 hours
Solar Activity: Low, with occasional small common class flares. There are currently six sunspot regions on the Earth-facing disc, most small and simple and either stable or decaying. Two regions are moderately sized, one of which in the northeast is the largest on the disc and also moderately magnetically complex. This region is also the only region which has displayed slight growth recently, with new small peripheral spots developing.
No Earth directed CME's were observed in available imagery.
Solar Wind / Geomagnetic Activity: Solar winds were predominantly Slightly Elevated around 400-450 km/s. The strength of the solar wind's magnetic field was weak, while the important north-south component weakly fluctuated. Geomagnetic activity was Quiet to Unsettled.
Energetic Particles / Solar Radiation: The count rate of energetic particles (high energy protons) remained at Background, with no solar radiation storms observed.
Four-Day Space Weather Forecast Summary
Solar Activity: Solar activity is forecast to be Low, but with a chance of rising to Moderate due to isolated Moderate-class flares and a slight chance of a Strong flare.
Solar Wind / Geomagnetic Activity: A CME was seen leaving the Sun in the northeast at around 09/1557 UTC, with another CME observed after a Common class flare from a plage region in the southwest, around 09/1918 UTC. These have been assessed as relatively slow CMEs that are largely missing, but may give glancing impacts on day 4 (June 13). Otherwise, current Background solar winds are expected to continue until the onset of a solar wind enhancement on day 1 (11 Jun), with winds becoming Elevated and perhaps Strong. The winds are expected to ease through day 3 (13 Jun). Geomagnetic activity is expected to be Quiet at first, but expected to rise to Active to Minor Storm with the fast wind onset, before easing again to be mainly Quiet to Unsettled by day 3 (13 Jun). However, any CME arrival could bring a further Active spell with a slight chance of Minor Storms.
Energetic Particles / Solar Radiation: The count rate of energetic particles (high energy protons) is forecast to remain at Background, with no solar radiation storms occurring.

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.
