US-SPACE-SUN
This 04 November, 2003 NASA Solar and Heliospheric Observatory EIT (Extreme ultraviolet Imaging Telescope) image shows giant sunspot 486 (lower-R) 486 unleashing another powerful solar flare. Ionizing radiation hit Earth's atmosphere soon after the explosion and caused a severe radio blackout, which radio listeners noticed across North America. This latest flare from sunspot 486 could be historic. The blast saturated X-ray detectors on board GOES satellites for 11 minutes. The last time a flare did this, on 02 April, 2001, it was classified as an X20--the biggest ever recorded at the time. This latest solar flare appears to have been even stronger. Sunspot 486 is near the sun's western limb, which means the blast was not directed very much toward Earth. Even so, sky watchers should be alert for auroras on 05 or 06 November when a coronal mass ejection (CME) is expected to deliver a glancing blow to our planet's magnetic field. AFP PHOTO/NASA
