America : A 75,000-mile-wide HOLE has appeared on the sun – and experts warn it could knock out communications satellites and cause blackouts on Earth
- Nasa spotted the sunspot last week, but it has lingered through to today
- Dubbed AR2665, it is big enough to be spotted from Earth
- Experts have warned the spot is large enough to produce ‘M-class’ solar flares
- These can cause stunning auroras, and wipe out communication satellites
A huge spot has appeared on the sun that could send dangerous solar flares down to Earth.
The sunspot, dubbed AR2665, is 74,560 miles (120,000 kilometres) wide – big enough to be seen from Earth.
Experts have warned that the spot is large enough to produce ‘M-class’ solar flares, which can cause radio blackouts on Earth, knock out communications satellites and create radiation storms.Tspot is the first to appear after the sun was spotless for 2 days. Like freckles on the face of the sun, they appear to be small features, but size is relative: The dark core of this sunspot is larger than Earth as shown by this graphic
