We report the detection of an Hα trail of 85 kpc projected length behind galaxy 2MASX J11443212+2006238 in the nearby cluster of galaxies Abell 1367. This galaxy was discovered to possess an extended component in earlier, deeper Hα observations carried out with the Subaru telescope. However, lying at the border of the Subaru field, the extended Hα tail was cut out, preventing the determination of its full extent. We fully map this extent here, albeit the shallower exposure.
Key words: galaxies: evolution / galaxies: clusters: individual: A1367 / galaxies: individual: 2MASX J11443212+2006238 / galaxies: interactions
