Solar winds exceeding 600 kilometers per second hit the Earth  

There was no such prediction

A few days ago, the Earth’s magnetic field was hit by solar winds that exceeded 600 kilometers per second. And while there was no immediate danger, they caused impressive and unexpected auroras. In fact, the aurora became visible for the first time in five summers from Denmark.

The incident was not in the forecast and the auroras surprised us. – SpaceWeather

Solar winds are streams of charged particles and plasma that cannot be contained by the Sun’s gravitational field and reach Earth. By observing the surface of the Sun, scientists can create a “weather report” on solar activity and we usually know when we will have solar flares or solar winds and what their intensity will be. However, this one escaped us.

NASA ‘s Deep Space Climate Observatory observed weak solar winds that increased significantly and unexpectedly during Sunday. The source of the solar storm remains unknown, but SpaceWeather speculates that it is the harbinger of solar winds coming from the Sun’s equator. But we may just have missed a CME.

An inconsistency in the solar wind data on August 7 indicates a shock wave existed in the solar wind. These days the Sun’s activity produces so many smaller bursts that it’s easy to miss the faint CMEs headed for Earth.

At the time of writing, solar wind speeds are just under 600 km/s and are categorized as G2 solar storms, with G1 being the weakest and G5 being the strongest. G2 storms can affect power systems at high altitudes, as well as spacecraft trajectory predictions.
