A giant hole appeared on the Sun’s surface this weekend, blasting solar winds towards Earth. The phenomenon, officially known as a ‘coronal hole’, isn’t actually a hole in the Sun’s surface
Well, as hot gases and solar winds escape through the coronal hole, the Sun’s surface beneath it becomes cooler and less dense than the areas around it.
And when the Sun is viewed in ultraviolet light, as in the picture below, these cooler areas show up as black – creating the illusion of a, frankly massive, hole in the Sun. In fact, this one is about the size of 60 Earths.

Apart from maybe the odd light show in the sky here and there and some possible electrical interference I think the most obvious effect will be extreme weather.
