The sun has had no sunspots for almost two weeks (as of Feb. 1, 2018) and just has a single, tiny one that appeared on Jan. 31, 2018. The video shows a rotating sun in filtered light for the past week, but it is even hard to tell the sun is rotating since there are just about no features. Even the small spot that appears on the 31st is hard to see. This spotless period is a prelude to the approaching period of solar minimum next year, when the sun's activity will be at the low end of its 11-year cycle.
