A 500,000-mile-wide coronal hole on the sun is blasting solar wind at Earth, potentially igniting vibrant auroras and minor geomagnetic storms on Jan. 31 and Feb. 1 ...

Solar news: NOAA forecasts a geomagnetic storm alert and viewline map for Northern Lights sightings in the US for June 24-25.

A solar, or geomagnetic, storm occurs when the charged particles within solar wind interact with Earth's magnetic field, causing a significant disturbance, according to NASA.

SpaceWeatherLive.com reported solar wind speeds peaking at 1002 km/sec, with the interplanetary magnetic field (IMF) strength (Bt) reaching 25 nT and a southward Bz component of -18 nT.

A geomagnetic storm is a disturbance in Earth’s magnetic field caused by solar activity. There’s a reaction called nuclear fusion that occurs continuously deep within the Sun’s core.
