Two waves of solar material blown out by powerful sun eruptions n this week are hitting the Earth now, and could amplify the aurora displays for observers in northern regions. Scientists with NOAAs Space Weather Prediction Center in Boulder, Colorado, expected the first wave of solar flare particles — unleashed by a so-called coronal mass ejection, or CME, on Monday (Sept. 8) — to reach Earth Thursday night (Sept. 11). A second wave, this one caused by a massive solar flare on Wednesday, is due to arrive between Friday and early Saturday. We do expect these storm levels to cause significant auroral displays across much of the northern U.S. on Friday night, SWPC Director Thomas Berger told reporters on Thursday. With clear skies currently forecast for much of these regions, this could be a good opportunity for auroral sightings. [Amazing Aurora Photos of 2014]
