Spotless sun, G2 watch active
Our sun is spotless today. The NOAA SWPC reports that there are no numbered sunspot regions on the earth-facing side of the solar disk and that means our sun is devoid of sunspots for the first time since 18 July 2014. As a result, solar activity is at very low levels and the last registered solar flare took place three days ago!
