From an article by Meteorologist Paul Dorian Vencore, Inc:
“For the second time this month, the sun has gone completely blank.
This is a more dangerous time for astronauts as the increase in potent cosmic rays can easily shatter a strand of human DNA. Also, during years of lower sunspot number, the sun’s extreme ultraviolet radiation (EUV) drops and the Earth’s upper atmosphere cools and contracts. With sharply lower aerodynamic drag, satellites have less trouble staying in orbit— a good thing.
On the other hand, space junk tends to accumulate, making the space around Earth a more dangerous place for astronauts.”
