Abstract
A TELEGRAM from Dr. Harlow Shapley announces the rediscovery of Comet Pons Winnecke on May 3, its magnitude being 14. A definitive orbit for this comet was computed by Mr. J. G. Porter and members of the Computing Section of the British Astronomical Association, and an ephemeris is given in the "Handbook" for 1945. The correction to the computed perihelion is + 2·6 days, and the result must be considered very satisfactory as the comet passes just over 0·6 unit from Jupiter, suffering considerable perturbations. Dr. Shapley has also announced the rediscovery of Comet Kopff on May 7d. 9h. 10m., U.T., its magnitude being 13. An orbit and ephemeris were computed by Messrs. W. E. Beart and W. P. Henderson and are given in the "Handbook" of the British Astronomical Association for 1945. A correction of about –8 m. in R.A. to the ephemeris is indicated from the observation.
