A geomagnetic storm classified G4 – a very strong storm – took place last night (June 22-23, 2015), sparking displays of auroras, or northern lights. The reports we saw had them as far south as the U.S. state of Virginia and similar latitudes, but we might hear of even more southerly sightings today. The last on this scale happened in March, when auroras were seen as far south as New Mexico. The display might last into the night of June 23-24. Your best chance to catch auroras is to find a country location, far from city lights.
