PGC 1228197 known as WINGS J211347.41+022834.9 and JO206, is a large spiral galaxy located 700 million light-years away towards the constellation of Aquarius. The galaxy is estimated to be at least 160,000 light-years in diameter, making it somehow bigger than the Milky Way. With a radial velocity of 15,226 kilometers per second, it is slowly drifting away.

PGC 1228197 is a member of a poor galaxy cluster called II ZW 108. It has a stellar mass of 8.5 × 10 M○.

PGC 1228197 is classified as a jellyfish galaxy. It has a lengthy tail that is ≥90 kpc wide, with ionized gas stripped from the galaxy. The galaxy is surrounded by its own magnetized intracluster medium drape.

Such process is caused when it interacts with other galaxies causing it to run into intracluster medium. The galaxy then undergoes a process of ram-pressure where its gas is stripped, forming long galactic tendrils of stars. Because matter is accreted into its supermassive black hole, its active galactic nucleus is trigged.
