Abstract
AN optical jet, extending 10 arc min from the elliptical galaxy M89 (NGC4552) is reported here. Two low surface brightness shells partly surround the galaxy and a much fainter arc, 13 arc min away has also been detected. The jet was found on five deep plates of the Virgo cluster obtained by the 1.2-m UK Schmidt Telescope. Three sky-limited IIIaJ (bandpass 395–530 nm) and two IIIaF (630–685 nm) plates were taken on hypersensitised1 emulsions. A slightly different plate centre was used for two of the plates.
