Number 35... the X1.6 solar flare that occured on September 10 was the 35th X-class solar flare of this solar cycle. It was a powerful solar flare but as far as X-class solar flares go... it was with a peak flux of X1.6 actually only a relatively modest solar flare when you consider that solar flares can get 10 or even 20 times stronger than that. The true X-treme solar flares are the so called ''super X-class solar flares''... X-class solar flares that peak at X10 or even higher. We have yet to see such a solar flare this cycle... or have we?
A lot of people come to SpaceWeatherLive to follow the Solar activity or if there is a chance to see the aurora, but with more traffic comes higher costs to keep the servers online.
