Detailed explanation-1: -In general, solar flares are nothing to worry about. So-called “killer flares” do not exist and although solar flares can significantly disrupt the technological world, they don’t contain enough energy to do any lasting damage to Earth itself.

Detailed explanation-2: -"Harmful radiation from a flare cannot pass through Earth’s atmosphere to physically affect humans on the ground,” the space agency said in a September 2017 statement. “However-when intense enough-they can disturb the atmosphere in the layer where GPS and communications signals travel."

Detailed explanation-3: -Therefore, solar flares pose no direct danger to humans on Earth. However, this absorption of high-energy electromagnetic radiation can temporarily increase the ionization of the upper atmosphere, which can interfere with short-wave radio communication, and can temporarily heat and expand the Earth’s outer atmosphere.

Detailed explanation-4: -“At its most active, called solar maximum, the Sun is freckled with sunspots and its magnetic poles reverse.” That sort of solar activity has impacts here on Earth. It could disrupt navigational tools like GPS, cause blackouts and problems with power grids, and cause radio communications issues.
