Halloween Solar Flare Headed For Earth; Could Disrupt Power Grid...

SUN DAY Halloween solar flare headed for Earth could trigger Northern Lights this weekend – and disrupt power grid 

THE SUN launched a massive solar flare yesterday that's headed in Earth's direction – the strongest storm seen in the current weather cycle. The volley of radiation may trigger the northern lights if it collides with our atmosphere, and could cause major issues for power grids, experts suggest. NASA’s Solar Dynamics Observatory, which tracks the Sun's activity, captured an image of the event at 11:35 a.m. EST (4:35 p.m. BST) on Thursday. It has already caused a temporary, but strong, radio blackout in parts of South America, according to the U.S. Space Weather Prediction Center (SWPC). The flare is the result of a coronal mass ejection (CME) – a huge expulsion of plasma from the Sun's outer layer, called the corona. In a blog post, Nasa said that the "significant" flare has been classified an X1. Flares are ranked by letter, with the biggest labelled as "X-class." The smallest flares are "A-class." Higher numbers designate more intense flares. Nasa logged an X28 in 2003, though an X1 is still a significant eruption. Source
