144P - Kronck’s Cometography

Discovery:

 Yoshio Kushida (Yatsugatake South Base Observatory, Japan) discovered this comet on Technical Pan 6415 patrol film shot with a 0.10-m f/4.0 telescope on 1994 January 8.81. He estimated the magnitude as 13.5. The comet was near the edge of the photograph and exhibited a strong central condensation within a coma 1-2 arc minutes across.

Recovery:

The comet's next perihelion date was 2001 June 27 and it was recovered by C. E. Delahodde and O. R. Hainaut (European Southern Observatory, La Silla) on 2000 July 25. Their observation on July 27 was also the last obtained during this apparition.
