NGC 6984 is a barred spiral galaxy located 180 million light years away in the constellation Indus. It is a Type II Seyfert galaxy, a type of Active galactic nucleus (AGN). It is situated south of the celestial equator, and is visible with the help of a telescope having an aperture of 10 inches (250 mm) or more. It was discovered on 8 July 1834 by British astronomer John Herschel.

NGC 6984 is notable for having been the host of two supernovae which occurred in the same location (< 0.4 arcsec), about 1 year apart: SN 2012im (type Ic, mag. 18.9), first known as SNhunt142, and SN 2013ek (type Ib/c, mag. 16.9). Hubble Space Telescope observations were initiated by Dr. Dan Milisavljevic. NASA's press release about SN 2013ek said:

"It is so close to where SN 2012im was spotted that the two events are thought to be linked; the chance of two completely independent supernovae so close together and of the same class exploding within one year of one another is a very unlikely event. It was initially suggested that SN 2013ek may in fact be SN 2012im flaring up again, but further observations support the idea that they are separate supernovae — although they may be closely related in some as-yet-unknown way."
