Abstract

After unsuccessful efforts to find the eclipsing binary MO Puppis in the sky, a search of the discovery plates at Sonneberg Observatory revealed that its published position was in error by one degree in declination. Once located, observations on Harvard College Observatory plates produced a probably period, which was then confirmed and improved by visual observations.
