Please help identify unknown homescreen status bar icon

Android 8.0, running on HTC 10, on Verizon Wireless.

Between the Bluetooth and alarm clock icons, is a new icon that I do not recognize. It is a circle with a horizontal line in the middle. The horizontal line does not touch the edges of the circle.

Welcome to AC.

That would be Do Not Disturb...
