An unusually strong solar storm headed toward Earth could produce northern lights in the U.S. and potentially disrupt communications this weekend.

An unusually strong solar storm headed toward Earth could produce northern lights in the U.S. and potentially disrupt communications this weekend.

The National Oceanic and Atmospheric Administration issued a rare geomagnetic storm watch — the first in nearly 20 years. The watch starts Friday and lasts all weekend.

NOAA is calling this an unusual event, pointing out that the flares seem to be associated with a sunspot that’s 16 times the diameter of Earth. An extreme geomagnetic storm in 2003 took out power in Sweden and damaged power transformers in South Africa.

The latest storm could produce northern lights as far south in the U.S. as Alabama and Northern California, according to NOAA.

    Go out anyways and look north, there’s a good chance you’ll see something.

      I remember watching the aurora from the Bastille Day solar storm in 2000. The whole sky in NorthWestern Ontario was red … like a red umbrella shimmering down. I’ve never seen an aurora like it since.

      I assume there is like no cloud penetrative? We have light clouds and fog all week and that sucks.

        Yeah they can’t really be seen through clouds aside from maybe the clouds looking slightly brighter.
