APOD: 2019 March 6 - A February without Sunpots

See Explanation.  Clicking on the picture will downloadthe highest resolution version available.

There were no sunspots in February.  Called a "solar minimum", the last time this happened was 11 years ago.  Environmental effects include the sun dimming, decreased solar wind, the collapse of Earth's outer atmosphere ("thermosphere"), and reduced drag on satellites.
