"The White Spot on Saturn's Ring, recently announced by Terby of Belgium, was observed at this Observatory [Warner Observatory, Rochester] on the evening of March 14th [1889] both by Professor Brooks and myself. In consequence, however, of its faintness, and of the bright moonlight in which it was viewed, it was a difficult object; but as we both saw in the same position and of the same size and shape, there could be no doubt in the mind of either of us that we had seen the “spot” which appeared as a narrow band extending across both outer rings, its western boundary being in contact with the black notch termed as shadow of the ball on the ring."
