Solar physicists predict that northern states in the United States may see the aurora borealis on Sunday after a massive eruption was observed on the sun by the National Solar Observatory yesterday.

Not unusually, Friday’s massive eruption of solar magnetic filaments was directed toward Earth.
This was described as a “full halo” CME. SpaceWeather.com. CME stands for coronal mass ejection, in which magnetic fields and clouds of charged particles from the sun stream into space at up to 1,900 miles (3,000 kilometers) per second.
If directed towards Earth, it can take several days to reach Earth, where it creates magnetic storms that often result in the appearance of the aurora borealis.
The website says it could hit Earth’s magnetic field this weekend, suggesting midnight on Sunday, November 5th. It is predicted that a G2 class (moderate) magnetic storm accompanied by an aurora will occur in the northern states of the United States.
Early monitoring of space weather reaching Earth suggests the aurora may be better than expected. X’s SpaceWeatherLive said, “If this value persists, the geomagnetic storm conditions up to the G3 (Kp7) level are expected to be stronger than predicted.”
National Oceanic and Atmospheric Administration’s Space Weather Prediction Center 3 day weather forecast predicts the peak will be between 03:00 and 06:00 UTC on Monday, or between 22:00 and 01:00 EST from Sunday to Monday.
According to NOAA, auroras are caused by collisions of electrons in the upper reaches of Earth’s atmosphere. They form about 50 to 300 miles (80 to 500 kilometers) above the Earth’s surface.
I wish you clear skies and big eyes.
