A giant sunspot on the sun has erupted for the sixth time in a week.

The sunspot, which is 14 times larger than Earth, has erupted with three flares in the last 48 hours.

‘A giant active region on the sun erupted on Oct. 26, 2014, with its sixth substantial flare since Oct. 19,’ NASA said.  ‘This flare was classified as an X2-class flare and it peaked at 6:56 a.m. EDT.  This is the third X-class flare in 48 hours, erupting from the largest active region seen on the sun in 24 years.”

Christopher Balch of the Space Weather Prediction Center said that the flare had an impact on radio signals that used the upper atmosphere.  A few radio communications systems were completely blacked out by the flare for a short time.

The sun has been in an aggressive time of activity after months of almost silence.

The sunspot, which continues to grow, has been described as “menacing” by astronomy experts.
