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
Although solar wind speeds remain elevated, the likelihood of auroral activity is diminishing as geomagnetic conditions gradually ease. The auroral oval is expected to remain mostly confined to higher latitudes through Saturday UTC night, with mainly low geomagnetic activity thereafter.
Southern Hemisphere
Although solar wind speeds remain elevated, the likelihood of auroral activity is diminishing as geomagnetic conditions gradually ease. The auroral oval is expected to remain mostly confined to higher latitudes through Saturday UTC night, with mainly low geomagnetic activity thereafter.

Forecast overview
Space Weather Forecast Headline: Diminishing chance of G1 Minor Storms Day 1. Likelihood of isolated Moderate class flares.
Analysis of Space Weather Activity over past 24 hours
Solar Activity: Solar activity is currently Low, with only minor Common-class flares observed.
There are currently eight sunspot regions on the Earth-facing disc. A bipolar region In the northwest has several small spots surrounding its large positive-polarity spot but with some decay evident in the smaller spots in recent imagery. Another bipolar region in the northwest, continues to grow as additional spots emerge. A bipolar region in the southwest quadrant has shown some overall decay, especially in the large trailer and smaller intermediate spots. A developing bipolar region in the northeast continues to show modest growth, especially in its lead portion. A small but developing bipolar region is located in the far southeast disc. Remaining regions active regions are generally stable and relatively small, with simple magnetic structures.
No Earth-directed Coronal Mass Ejections (CMEs) were observed.
Solar Wind / Geomagnetic Activity: Solar wind conditions were indicative of waning CME influence. Solar wind speeds, measured at L1 by ACE, were mostly in the range 550-650km/s, with a few short-lived peaks above 700km/s, and a maximum of 757km/s around 05/2012UTC. The magnetic field carried by the solar wind was initially strong but gradually decreased and returned to weak levels from around 05/1930UTC. The important north-south component was variable and showed a similar overall trend. Geomagnetic conditions were G1-G2/Minor-Moderate Storm levels (Kp 5-6) between 05/1200-2400UTC, then eased to Quiet to Active (Kp 2-4).
Energetic Particles / Solar Radiation: The count rate of energetic particles (high energy protons) remains at background with no solar radiation storms observed.
Four-Day Space Weather Forecast Summary
Solar Activity: Solar activity is forecast to remain generally Low, with a chance of Moderate-class flares and slight chance of Strong flares.
Solar Wind / Geomagnetic Activity: Recent CME influence has largely waned although solar wind speeds remain elevated, occasionally strong, near 600km/s. With no further Earth-directed CMEs currently forecast and the influence of both the recent CME activity and the coronal hole high-speed stream expected to gradually diminish further, solar wind speeds are likely to slowly decrease over the coming days.
Geomagnetic activity may still reach Active, with a diminishing chance of isolated G1/Minor Storm levels initially. However, conditions are expected to gradually ease to predominantly Quiet to Unsettled levels later on Day 1 (06 June), with similar levels likely for the remainder of the forecast period.
Energetic Particles / Solar Radiation: The count rate of energetic particles (high energy protons) is forecast to persist 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.
