E. Devinney and C. McCracken, Goddard Space Flight Center, report
that a spectrogram (dispersion 220 A/mm) obtained on Oct. 31.4
UT shows the gas-continuum ratio to be less than in comet 1975h.
Selected total visual magnitude estimates: Oct. 23.40, 9.6 (J.
Bortle, Brooks Observatory, 32-cm reflector); 30.40, 8.6 (R. Keen,
Boulder, Colorado, 15-cm reflector); Nov. 1.46, 9.0 (P. Maley,
Houston, Texas, 13-cm refractor); 2.46, 8.7 (Maley); 5.46, 8.8 (Maley).
