Daytime hunting only? I've found daylight-sunup and late PM-sundown just fine for calling, when there's a lot of moon. My theory is that prey animals have a better chance when the moon is full, so Wiley has to start earlier and/or stay later.
You have to be more careful about your own movements and being seen as a coyote comes to a call, of course. 50 to 100 feet of speaker wire, to get him focussed away from your hidey-hole is a help.
One or two shooter-guys sitting very still, upslope from the guy with the call, is a good system, if you have some helpers available.
Always remember that no matter what direction he comes from, he'll circle downwind to make the final approach upwind to the sound or bait.
