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.[1][2] 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.[3]

PGC 1228197 is a member of a poor galaxy cluster called II ZW 108. It has a stellar mass of 8.5 × 1010 M○.[4]
PGC 1228197 is classified as a jellyfish galaxy.[5][6] It has a lengthy tail that is ≥90 kpc wide, with ionized gas stripped from the galaxy.[7] The galaxy is surrounded by its own magnetized intracluster medium drape.[8]
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.[5][9][10] Because matter is accreted into its supermassive black hole, its active galactic nucleus is trigged.[11]
