PERIODIC COMET WHIPPLE (1985h)
     The recovery of this comet has been reported as shown below.
The observed position is in good agreement with the prediction on
MPC 9597 (elements on MPC 8274).

J. Gibson (Palomar Observatory). 1.6-m reflector and CCD.  The
   first two images are near the edge of frames and outside the
   reference star arrays.  Some frames show a tail 3" -4" long in
   p.a. 260-265; otherwise the images are stellar in appearance.
T. Gehrels (Kitt Peak).  SPACEWATCH camera 0.91-m telescope.
   Images identified and positions reduced by J. V. Scotti.  Some
   slight indication of diffuseness.


COMET MACHHOLZ (1985e)
    The following ephemeris continues that on IAUC 4078.  It seems
unlikely that any substantial component remains (cf. IAUC 4083).
