THE IMPACTS HAVE BEGUN: minor CME hit Earth’s magnetic field on Aug. 17th (0303 UT). It could be the first of several CME strikes in the days ahead. NOAA forecasters say their cumulative effect could cause strong G3-class geomagnetic storms, especially on Aug. 18-19. During such storms naked-eye auroras can descend into the USA as far south as Illinois and Oregon (geomagnetic latitude 50 degrees). Cameras with sensitive night-sky settings may record auroras even farther south than that
