A powerful solar eruption is expected to blast a stream of charged particles toward Earth tomorrow (Jan. 24), as the strongest radiation storm since 2005 rages on the sun.

Early this morning (0359 GMT Jan. 23, which corresponds to late Sunday, Jan. 22 at 10:59 p.m. EST), NASA's Solar Dynamics Observatory caught an extreme ultraviolet flash from a huge eruption on the sun, according to the skywatching website Spaceweather.com

According to NOAA, this is the strongest solar radiation storm since May 2005, and as a precaution, polar flights on Earth are expected to be re-routed within the next few hours, Kathy Sullivan, deputy administrator of NOAA, said today at the 92nd annual American Meteorological Society meeting in New Orleans, La.
