  Saturn's quasi-periodic planet-encircling storms are the largest convecting
outbursts in the Solar System. The last eruption was in 1990. A new eruption
started in December 2010 and presented the first-ever opportunity to observe
such episodic storms from a spacecraft in orbit around Saturn. Here, we analyze
images acquired with the Cassini Imaging Science Subsystem (ISS), which
captured the storm's birth, evolution and demise. In studying the end of the
convective activity, we also analyze the Saturn Electrostatic Discharge (SED)
signals detected by the Radio and Plasma Wave Science (RPWS) instrument. [...]
