Sunspots were seen from Spain's Canary Islands as a geomagnetic storm was expected to reach the Earth.
What is a geomagnetic storm
A geomagnetic storm is a temporary disturbance of the Earth's magnetosphere caused by a solar wind shock wave and/or cloud of magnetic field that interacts with the Earth's magnetic field.
According to a image published on APOD the Sun's disk showed five sunspots, quite a lot considering that during the solar minimum in solar activity of the past few years, most days showed no spots.
