Delisle Stewart discovered IC 1637 = D.S. 144 on a plate taken in Arequipa in 1899. His published position is accurate.

600/800mm - 24" (11/7/18): at 200x; faint, moderately large, slightly elongated, 1' diameter, low surface brightness. Very weak central brightening. Located 14' SSE of NGC 418. The contrast was poor during the observation due to low elevation of the galaxy and the nearby skyglow on the horizon.
