The timing of the event will be most important for who will see the auroras. NOAA SWPC has issued a Geomagnetic Storm Watch, anticipating G1 storm levels Friday afternoon (EDT), "with a chance for G2 storm levels if more favorable conditions are observed."Īlthough very strong geomagnetic storms have been known to cause problems with orbiting spacecraft and satellites, and with power grids on the ground, weak and even moderate geomagnetic storms most often result in vibrant displays of the Aurora Borealis, aka the Northern Lights. As it passes, the magnetic field carried by this solar storm will likely result in a minor disturbance in Earth's geomagnetic field, causing what's known as a geomagnetic storm. However, it is aimed almost directly at us.įorecasters with NOAA's Space Weather Prediction Center are expecting the CME to arrive here sometime during the day on Friday. This 'solar storm' is moving fairly slowly through space, taking roughly three days to cover the 150 million kilometres between the Sun and Earth. The right panel is the view of the solar corona from NASA/ESA's Solar and Heliospheric Observatory (SOHO) from July 4. The left panel shows the view of the Sun from NASA's Solar Dynamics Observatory on July 5, highlighting AR 3559.
Monday night, a large active region on the Sun, which solar scientists have named AR 3559, released an immense cloud of charged solar particles out into space - a Coronal Mass Ejection, or CME. Skywatchers across Canada may see displays of the Northern Lights on Friday night due to a passing solar storm.
Eyes to the sky for the start of the weekend.
