ABSTRACT COMET OR NEBULOUS MINOR PLANET?—At the Konigstuhl Observatory a photograph talten on April 3 showed what seemed to be a new minor planet, which received the designation 1916 ZK. Its


daily motion was —o.6m. and + 3′, whilst its magnitude was 13.0 (_Astronomische Nachrichten_, 4841). Three days later, on another photograph, it presented a nebulous appearance. This was


more strongly developed by April 27 (_Astronomische Nachrichten_, 4843). Dr. Max Wolf's observations have been confirmed at the Babelsberg Obversatory (_Astronomische Nachrichten_,


4843). On April 30 the nebulosity involved a stellar nucleus. This remarkable body evidently bears a likeness to Neujmin's comet 1913_c_, which resembled a minor planet when first


discovered, but a few days later developed a weak cometic chevelure; and the latest, observations indicate that it is really a new comet. The position of the object on discovery was:—April


3, R.A. 12h. 52.9m., declination +0° 11′ on April 30, 12h. 58.9m., +2° 39.6′. The daily motion on April 27 was ‘ 0.5m. and +5′ and the magnitude was 13.3. Access through your institution Buy
