COMET KOHOUTEK-IKEMURA (1975b)
     Dr. K. Osawa, Director of the Tokyo Astronomical Observatory,
cables that Ikemura has discovered a comet, as shown below.  The
comet is clearly identical with the one observed by L. Kohoutek on
Feb. 27 (IAUC 2752), but the motion is reversed, and the Feb. 9
observation must therefore refer to a different object.  Further
observations of comet Kohoutek-Ikemura were subsequently identified
by N. Kojima (Ishiki) and by R. E. McCrosky on a plate taken by G.
Schwartz with the 41-cm astrograph at Harvard Observatory's Agassiz
Station.  All these observers described the comet as diffuse,
without condensation.

     The following orbital elements and ephemeris, based on approximate
observations only, are by K. Hurukawa and T. Hirayama:

       T = 1975 Mar. 23.45 ET    Peri. =  33.2

COMET KOHOUTEK
     Dr. L. Kohoutek, Hamburg Observatory, informs us that the sense
of motion of the Feb. 9 cometary object is unclear but that he has
possibly reobserved this object as follows:

     1975 UT          R. A. (1950) Decl.      m1
     Feb. 27.79965    4 34.2     +20 13       15
