This is a Horizon icon. We've made it in iOS style, first introduced in iOS version 7 and supported in all later releases up until now (at least iOS 11). This style is based on thin two-pixel lines and is optimized for 50x50 px. Unlike other vector icon packs that have merely hundreds of icons, this icon pack contains 13,000 icons, all in the same style and quality.
The image is of a circle with a line through the top portion of it. The line is horizontal and above center. The line is solid and so is the circle and rays coming from the circle above the line. Below the line, the circle and the rays are dotted. In the center of the dotted part of the circle is the number 12 with a degree symbol.
