Corwin's Notes
=====
NGC 443 = IC 1653. D'Arrest has a single observation of the galaxy from the
night of 8 October 1861. He published it in AN 1500, and again in his big
monograph. The declination is 0.5 arcmin greater in the monograph, but it is
still nine arcmin too small. I suspect a digit error in the arcminute 10's
place. With that, the position would be within an arcmin or so of the true
position. D'A's note about the 15th magnitude star 8.3 seconds of time
preceding the galaxy is correct -- the actual distance is 7.9 seconds.
Javelle rediscovered the galaxy over 40 years later in 1903. His micrometric
observation, re-reduced with respect to a modern position for his comparison
star, is within a couple of arcseconds of the modern positions.
