A solar storm is expected to hit Earth's magnetic field early Saturday and last through Sunday. Scientists said it will be a minor event and they have notified power-grid operators, airlines, and other potentially affected parties. “We don't see any ill effects to any systems," said forecaster Joe Kunches at the U.S. government's Space Weather Prediction Center in Boulder, Colorado. The storm started Thursday as the sun unleashed a massive flare that sent a cloud of highly charged particles racing toward Earth. It was the sixth time this year that such a powerful solar outburst has happened. None of the previous storms caused major problems.
