From The Stargate Omnipedia

Designation given to the planet where the Ori successfully created and activated the second Supergate in the Milky Way Galaxy. Like Kallana, this planet was most likely consumed by a black hole to form the event horizon for the Supergate.

SG-1, aboard the Odyssey, traveled to the Pegasus Galaxy equipped with an eighth-chevron dialing crystal and a Milky Way gate. With these they dialed a standard Stargate placed at the coordinates of PGG-002. They then detonated directed warheads at the open wormhole, causing it to leap instead to the Supergate -- activating it and blocking the Ori from being able to dial in again.
