1859 Solar Superflare Effect on Ozone Layer

Solar ‘superflare’ shredded Earth’s ozone. ‘The largest solar flare in the last 500 years may have shredded Earth’s ozone layer to a greater extent than human-made chemicals have in recent decades, new research suggests, but the effect was only temporary. If such a flare occurred today, it would likely be even more damaging to the ozone and could increase the rate of skin cancer around the world. On 1 September 1859, the Sun expelled huge quantities of high-energy protons in a ‘superflare’. The event was seen on Earth by an observer who noticed a white spot on the Sun suddenly brighten for about five minutes.’
