Cape Canaveral (USA), May 10 (AP) A strong solar storm headed toward Earth could produce northern lights in the US and potentially disrupt communications this weekend.

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

NOAA said the sun produced strong solar flares beginning Wednesday, resulting in five outbursts of plasma capable of disrupting satellites in orbit and power grids here on Earth. Each eruption — known as a coronal mass ejection — can contain billions of tons of solar plasma.

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.
