Abstract. Periodic comet 119P/Parker-Hartley, discovered on 1989 March 2 at Siding Spring, had been identified with 1986 TF, an object reported as a minor planet by both the Klet Observatory and Brorfelde. While P. Jensen reported in 1989 that the object is slightly diffuse compared with images of other minor planets, no report came from the KletObservatory. The re-analysis of plates from the Klet archive shows evident coma indicating cometary activity before perihelion.
