GEOMAGNETIC STORM WARNING: A large hole in the sun's atmosphere is facing Earth and spewing solar wind in our direction. Estimated time of arrival: Oct. 24-25. Minor G1-class geomagnetic storms are likely when the gaseous material arrives. Wind speeds are expected to reach 700 km/s, sparking bright auroras around the Arctic Circle and maybe even in northern-tier US states from Maine to Washington. Aurora alerts: SMS Text.
