The sunspot spotted by NASA as our sun creeps toward its solar minimum is 75,000 miles wide. That has huge implications for our satellites and communications systems, and the sunspot could cause some blackouts on Earth.
The huge sunspot has the potential to send out dangerous solar flares known to take out important communication equipment, satellites, and even huge sections of the power grid. This sunspot is the first to appear after the sun was spotless for 2 days and the dark core is larger than the Earth.
