Earth has attacked by the solar flare. This incident occurred at 1:12 pm ET on January 27, 2012 and peaked at 1:37. Power released by these events reached 0.00018 watts per meter square (type X1.8). An enormous energy. This energy causes the loss of radio contact for an hour on sunlit side of Earth, especially in areas of low lattitudes. Beside causing the loss of radio contact, low-frequency navigation signals degraded for about an hour (R3 scale according to NOAA). Flares also causes a number of corona mass escape into space and drive up to the speed of 1500 miles per second. NASA officially announced this fact.
NASA:"The sun unleashed an X1.8 class flare that began at 1:12 PM ET on January 27, 2012 and peaked at 1:37. The flare immediately caused a strong radio blackout at low-latitudes, which was rated an R3 on NOAA's scale from R1-5. The blackout soon subsided to a minor R1 storm. Models from NASA's Goddard Space Weather Center predict that the CME is traveling at over 1500 miles per second. It does not initially appear to be Earth-directed, but Earth may get a glancing blow."

Although no direct impact to human life, but people who live dependent on technology is the most sense.
