Lightning can heat the air it passes through to temperatures of about 30,000 °C (54,000 °F). That is regarded as 5 times hotter than the surface of the sun. The discharge process, or return stroke, of the lightning is the most luminous part where the electric current moves through the channel. One observation found that the rate at which the return stroke current traveled was around 100,000 km/s (or one-third the speed of light). Global monitoring indicates that lightning on Earth occurs at an average frequency of approximately 44 (± 5) times per second.

It’s pretty sick that some of the most extreme high energy phenomena in the universe take place right here on earth.
