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, it’s 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.
