Sun sends out another `X-class` flare
Washington: NASA`s Solar Dynamics Observatory has captured an image of the sun showing an X1.1 class flare that peaked at 11:26 p.m. EST on Nov. 7, 2013.
This is sun`s its sixth significant flare since Oct. 23, 2013, peaking at 11:26 p.m. EST on Nov. 7, 2013.
Solar flares are powerful bursts of radiation. Harmful radiation from a flare cannot pass through Earth`s atmosphere to physically affect humans on the ground, however-when intense enough-they can disturb the atmosphere in the layer where GPS and communications signals travel.
Active region 1890 is bigger than Jupiter and has produced numerous flares, including 2 X-class, since emerging over the sun`s eastern limb on Nov. 2, 2013.
This flare is classified as an X1.1 flare. X-class denotes the most intense flares, while the number provides more information about its strength. An X2 is twice as intense as an X1, an X3 is three times as intense, etc.
