You could still see where the planet is, because you'll have a spot in the sky without stars. The eclipse will last on the order of an hour or so (with considerable variation depending on orbital radius and planet size), after which the moon will go out of the planet's shadow and you will be able to see at least a crescent of light on the limb of the planet...

Regular eclipses like that, even if somewhat rare, would have some interesting effects on native wildlife. Mating flurries, pollen explosions, and nocturnal predators having a heyday from the deeper darkness.
