TWX 710-320-6842 ASTROGRAM CAM Telephone 617-864-5758 PERIODIC COMET HOLMES (1979f) This comet has been recovered by C.-Y. Shao and G. Schwartz with the 155-cm reflector at Harvard Observatory's Agassiz Station, and the following precise position is available: 1979 UT R. A. (1950) Decl. m2 July 20.29580 3 43 14.55 +35 49 59.9 19.5 The object is almost stellar in appearance, and in very close agreement with the predicted position (cf. MPC 4668). COMET RUSSELL (1979d) K. S. Russell, U.K. Schmidt Telescope Unit, communicates the following semiaccurate positions: 1979 UT R. A. (1950) Decl. m1 Observer July 15.39444 14 57 35.5 + 1 04 15 18 J. Barrow 16.39583 14 59 20.4 + 1 05 55 18 K. S. Russell The following ephemeris continuation is from orbital elements that slightly refine those on IAUC 3376. Accurate positions of this comet are urgently needed. 1979 ET R. A. (1950) Decl.
