NGC 3884 is a spiral galaxy located about 330 million light-years away[2] in the constellation Leo.[3] The galaxy was discovered by astronomer William Herschel on April 27, 1785[4] and is a member of the Leo Cluster.[5][6][7]
Although it is classified as a LINER galaxy,[8][9] NGC 3884 is also classified as a type 1 Seyfert galaxy.[2][10]
One supernova has been observed in NGC 3884. SN 2018yn (type Ic, mag. 18) was discovered by POSS on February 23, 2018.[11][12]
