     M. T. Carini, Science Programs, Computer Sciences Corporation;
and J. C. Noble and H. R. Miller, Georgia State University, write:
"We have observed the quasar 3C 446 in an unusually faint state
during 1991 Sept. and Nov.  Observations obtained at the Hall 1.07-m
telescope (+ nitrogen-cooled CCD camera) of Lowell Observatory
indicate the following magnitudes and colors:  Sept. 18, V = 18.00 +/-
0.01; Nov. 3, V = 18.28 +/- 0.03, B-V = +0.56 +/- 0.07; Nov. 6, V =
18.50 +/- 0.04, B-V = +0.47 +/- 0.05; Nov. 7, V = 18.49 +/- 0.03,
V-R = +0.59 +/- 0.07.  Further observations of this source are
encouraged."
