Solar storms can cause a wide range of effects from minor disruptions to satellite operations, to full-blown blackouts.
According to the astronomy website SpaceWeather.com, a crack has likely opened in the magnetic field in the early hours of July 22, between 4.30am and 11am BST.
The website said on Friday: “Solar wind poured in, fueling a period of geomagnetic unrest (Kp=4).
“So far no reports of auroras have been received, probably due to the glare of northern summer sunlight. Quiet conditions have since resumed.”
The website also informed of an erupting sunspot, AR2846, that was detected on July 20.
The sunspot hurled a CME out into space that was not expected to hit us head-on but could still have an impact on space weather.
The website added: “Normally, the location of the blast site would rule out an impact on Earth.
“However, the explosion’s debris squirted out sideways”
