Stay away from the flare. The strongest solar storm since 2005 has forced Delta airlines to reroute flights between the U.S. and Asia to avoid any chance of impact. The solar flare began Sunday night and will likely continue through Wednesday, with Delta expecting to continue the reroutes through Tuesday. Radiation may cause satellite disruptions or communication problems for polar-traveling airplanes, but its effects on the ground will be negligible. In 1989 a solar storm caused a massive blackout in Quebec, and last October a freak storm caused auroras to be seen as far south as Alabama.
