I am fascinated of how much power the sun has, and giving such flares means some disturbance to my mind, I felt unsafe going out expose to the sun especially looking up even at night time. Most around the duration up to 12 to 14 hours from September 6, 2017 . The radiation frequency is down below to around 3 khz wave, the speed of light is at 3 Million meters/second while the sun distance form earth is at 149.6 million kilometers. Be safe guys, although the speed of light is constant the frequency of radiation varies that could delay of the harmful ones. Be safe guys.
