The Coronal Mass Ejections (CME’s) throw particles into space which cause solar winds. Leads to Auroras

Leads to colder sun spots.

Detailed explanation-1: -CMEs travelling faster than the background solar wind speed can generate a shock wave. These shock waves can accelerate charged particles ahead of them – causing increased radiation storm potential or intensity.
Detailed explanation-2: -Large portions of the corona, or outer atmo-sphere of the Sun, can be explosively blown into space, sending billions of tons of plasma, or superheated gas, Earth’s direction. These CMEs have their own magnetic field and can slam into and interact with Earth’s magnetic field, resulting in geomagnetic storms.
Detailed explanation-3: -CMEs can also cause surges in electrical currents which overload power grids causing widespread blackouts. Also, according to NASA, CMEs can jostle Earth’s magnetic field which can impair radio transmissions and increase radio static in Earth’s ionosphere.
Detailed explanation-4: -When a CME reaches the Earth, its impact disturbs the Earth’s magnetosphere, setting off a geomagnetic storm. A CME typically takes 3 to 5 days to reach the Earth after it leaves the Sun therefore observing the associated solar flare or the ejection of CMEs from the Sun provides an early warning of geomagnetic storms.
