The solar storm of 1859, also known as the Solar Superstorm, which occurred during solar cycle 10, was the most powerful solar storm in history that is recorded. It lasted from August 28 to September 2. Also the largest flare of a solar storm was seen on this Superstorm, taking only 17 hours to reach the Earth. This is very strange becuase a solar flare normally reach the Earth between 3 to 4 days. Also the biggest geomagnetic storm ocurred and the aurorae was seen all over the wordl.
