A solar flare is a violent explosion in the Sun's atmosphere with an energy equivalent to a billion megatons, traveling normally at about 1 million km per hour (about 0.1% the speed of light), though sometimes much faster. Solar flares take place in the solar corona and chromosphere, heating plasma to tens of millions of kelvins and accelerating the resulting electrons, protons and heavier ions to near the speed of light. They produce electromagnetic radiation across the electromagnetic spectrum at all wavelengths from long-wave radio to the shortest wavelength gamma rays. Most flares occur around sunspots, where intense magnetic fields emerge from the Sun's surface into the corona. The energy efficiency associated with solar flares may take several hours or even days to build up, but most flares take only a matter of minutes to release their energy.

Solar flares were first observed on the Sun in 1859. Stellar flares have also been observed on a variety of other stars.

The frequency of occurrence of solar flares varies, from several per day when the Sun is particularly "active" to less than one each week when the Sun is "quiet". Solar activity varies with an 11-year cycle (the solar cycle). At the peak of the cycle there are typically more sunspots on the Sun, and hence more solar flares.

I have heard that they take about 9 minutes to reach earth, so from that, given the distance to the sun is 92,955,820.5 Miles, then

92,955,820.5 Miles / 9 minutes
or
619,705,470 Miles per hour

The speed of light is 670,616,629.384

so its Warp 0.92
