We will be soon!

The sunspot is just rotating into view, so its energy has been directed sideways and not directly at Earth. In coming days, if more major flares erupt as forecasters expect, they'll head right at us and radio blackouts, cell phone dropouts and other communications disruptions are more likely, scientists said.
Solar flares send radiation to Earth in about 8 minutes. Hours later, clouds of charged particles can engulf the planet. If the magnetic field of a storm is oriented opposite to our planet's protective magnetic field, gaps are created and radiation leaks to the planet's surface, potentially threatening astronauts aboard the International Space Station, sometimes shorting out satellites, and even causing terrestrial power grids to trip.
A severe geomagnetic storm produced aurora sightings along the northern tier of the United States, and even as far south as Arizona. Aurora are colorful sky lights triggered when charged particles excite molecules in the atmosphere.
According to one eyewitness from British Columbia, Canada, the solar storm is lighting up the sky. "It is 10 p.m. and the northern sky here is aglow, as if there were a major league night game at the nearby school," local resident of Cortes Island, John Sprungman, told SPACE.com. He reported no special effects at this moment other than the bright night sky.
There have been seven major flares in recent days, including a tremendous X-17 eruption Wednesday. An event Friday evening was an X-6. On Saturday, an X-1 and an X-2 erupted. Even an X-1 can cause severe disruptions. <snip>
