IC 3550, IC 3551, IC 3552, IC 3555, and IC 3563 are HII regions in the arms of NGC 4559, found on a Heidelberg plate by Max Wolf. IC 3554 and IC 3564 are stars superposed on the galaxy. See the IC numbers for a bit more information.― IC Notes by Harold Corwin

IC 3555 is a complex of HII regions in NGC 4559, easily seen on the print of Wolf's original plate. The position I've chosen is for the brightest knot.― IC Notes by Harold Corwin
