Lew, You mentioned that the June Arietids have a peak at 7hUT which is 3 am local for you. That is definitely during some dark hours for you...or near I guess for higher latitudes. But I believe the problem is that the Arietid radiant may not have risen above the horizon yet at that time? I haven't looked at it very closely, but I think that's what's happening. By the time the radiant does reaches the horizon, it is daylight. George
