Short summary
This study tests a recent suggestion that multi-month soft X-ray emissions from supernovae can destroy planetary ozone layers. To test this, we assume a year-long solar flare and evaluate the production of nitric oxide in the upper atmosphere and its transport down to the stratosphere. Our results suggest widespread catalytic destruction of ozone; however, these effects are limited to the upper edge of the ozone layer (near 40 km). Thus, the total column is only slightly affected (1–2 %).
