The consequences of a strong solar flare could also affect Earth in the coming days. The US space agency NASA announced that one of the most violent solar flares in recent years has now been observed. Such eruptions could disrupt communications waves, power grids and navigation signals, among other things, and also posed a risk to spacecraft and astronauts, it said.
The sun’s activity has been increasing again since December 2019. Approximately every eleven years, in a so-called solar cycle, there are phases of weak and strong activity. The sun is currently approaching a maximum.
