Sunspots are heading toward a low point expected in 2019-2020, NASA says
Solar minimum means certain types of activity, such as sunspots and flares, drop
But, it could cause coronal holes and enhance the effects of space weather
The sun is heading into a period known as solar minimum, during which activity at the surface will change form.
In this time, certain types of activity, such as sunspots and solar flares will drop but, its also expected to bring the development of long-lived phenomena including coronal holes.
According to NASA, solar minimum could also enhance the effects of space weather, potentially disrupting communications and navigation systems, and even causing space junk to hang around.
