OCCULTATION OF kappa GEMINORUM A BY 433 EROS
     Recent photographic and transit observations of Eros and/or kappa
Gem have been reported by P. Wild, Astronomical Institute, Berne;
H. L. Giclas, Lowell Observatory; R. S. Harrington, M. Miranian and
H. Crull, U.S. Naval Observatory; M. Mattei and D. Di Cicco, Harvard
College Observatory; and A. R. Upgren, Van Vleck Observatory.
These indicated that the occultation track would be well to the
west of all the predictions on IAUC 2737, and four hours before the
event the interpolation factor x was narrowed down roughly to the
range 1.5-1.6.  Photometry by C. A. Whitney, Harvard College
Observatory, on Jan. 18 indicated that Eros would be at minimum light
around Jan. 24d00h13m UT.  Dr. B. T. O'Leary, Hampshire College,
Amherst, Massachusetts, reports consistent, positive observations
of the occultation by three teams in western Massachusetts and
central Connecticut; the durations ranged from 2s.5 to 3s.4, and the
observed value of x was about 1.59.


COMET WEST
     Dr. Richard B. West, European Southern Observatory Sky Atlas
Laboratory, Geneva, reports that he has discovered a comet on a
plate taken by Pizarro and Ballereau at E.S.O. in La Silla:

     1974 UT          R. A. (1950) Decl.      m1
     Oct. 15.08607    1 06.2     -50 00       12

Daily motion: dR.A. = +1m.18, dDecl. = -1'.  The comet was diffuse, with
condensation or nucleus and a tail < 1o long.


NOVA PERSEI 1974
     The following selected visual magnitude estimates, referred to

10.5 (Bortle); 1975 Jan. 4.0, 11.0 (P. O. Taylor, Boynton Beach,
Florida); 5.02, 11.6 (Bortle); 9.0, 10.9 (M. J. Taylor, Boynton
Beach, Florida); 10.04, 11.6 (Bortle); 15.18, 11.8 (E. Mayer,
Barberton, Ohio); 17.06, 11.7 (Bortle); 18.0, 11.4 (M. J. Taylor).
