S. J. Bus (Lowell Obs., Anderson Mesa Sta.). 0.33-m astrograph.
G. Harlan (Lick Observatory). Average of measurements of ends of
trail on May 30; 0.51-m twin astrograph. Measured by B. Jones.
M. Koishikawa (Sendai Obs., Ayashi Station). 300mm telephoto lens;
comet diffuse, m1 = 8.0, coma dia. 2'; communicated by S. Nakano.
T. Kumamori (Murou Station, long. 136.0025 E, lat. +34.5672, elevation
400 m). 0.23-m f/4.4 reflector, Tri-X film; communicated by
H. Kosai, Tokyo Astronomical Observatory.
T. Seki (Geisei). 0.60-m reflector; communicated by Nakano.
The following improved parabolic elements, by the undersigned,
are from 8 observations, May 28-June 5. The comet will be within
20 deg of the sun during June 21-July 7; while the comet may reach m1
about 1 in late June, it will be much too close to the sun for viewing.
