The National Oceanic and Atmospheric Administration (NOAA) issued a G1 (minor) geomagnetic storm watch for Tuesday and Wednesday. The storm watch was issued "due to the arrival of a negative polarity coronal hole high speed stream," SWPC explained in a post online Sunday. C.

Its covering a surface area that could swallow 10 Earth’s whole! The new sunspot in question is nearly 80,0000 miles across, according to NASA. Massive sunspots like these are so large that they can be noticed by the naked eye, and were even regularly recorded by ancient Chinese...
