In a sure sign of the eclipse, the moon is now trolling the sun on Twitter. 

@NASAMoon, which dishes information from NASA about the moon, blocked @NASASun on Twitter this afternoon just as the real moon covered the sun entirely on the United States' west coast.

The literal and figurative shade was met with some sass by our fiery sun, @NASASun.
