Solar geomagnetic storms could sometimes cause telecommunication disruptions and power outages -- problem is, we can only predict if they're destructive 30 to 60 minutes before they arrive. Now,
galactic weatherman NASA Goddard scientist Neel Savani has started testing a new forecast model that will allow the agency to warn utility or telecommunication companies 24 hours beforehand. The agency says these damaging storms are caused by coronal mass ejections (CME), or massive bursts of gas and materials from the sun, which are aligned in the opposite direction of the Earth's magnetic field. We unfortunately don't have the tools to figure out a CME's configuration until it's close enough to the planet.
