Fascinating faculae provide a way for anyone with a small telescope to track the ups and downs of the solar cycle — even when there are no sunspots.
We examine the fascinating solar phenomena that anyone with a small scope and safe solar filter can see, whether the Sun's in eclipse or not.
Two big, naked-eye sunspot groups are putting on a splendid show this week. We're also in the crosshairs for a strong geomagnetic storm and possible auroras.

The Sun has been unusually quiet lately. Since the start of 2017, only a single tiny sunspot has made a brief appearance on the solar disk.
