Storms from 
the Sun


Sun Bubble, Bubble, Toil and Trouble
While our Sun does give us a steady stream of warmth and light, it also has weather that is turbulent and dynamic, provoking the cosmic equivalent of winds, clouds, waves, precipitation, and storms...

CME Hurricane Sol
One of the most important solar events from Earth's perspective is the coronal mass ejection (CME), the solar equivalent of a hurricane. A CME is the eruption of a huge bubble of plasma from the SunÝs outer atmosphere, or corona...

Aurora Storm Front
Coronal mass ejections occur at a rate of a few times a week to several times per day, depending on how active the Sun may be. And because of the size of the plasma clouds they produce, the odds say Earth is going to get hit by a CME from time to time...

Orbits Seeing the Invisible
Auroras are a visible sign of the magnetic mayhem in our atmosphere, but beyond that, the human eye canÝt detect much of what we call space weather...

Space Weather 
Effects Blackouts, Burnouts, and Bummers
Aside from bright auroras, there are other less benevolent effects of the connection between Sun and Earth. In fact, bright auroras are merely a visible sign that the balance of electrical and magnetic energy in EarthÝs magnetosphere has been upset...
