I was fishing lake okoboji and initially noticed what i thought what looked like venus but it was in the southwest at 1am which it shouldn't have been there. i caught a fish so my back was turned to the object for approximately 3 to 4 minutes. after i put my line back out and sat back down the object had closed the distance and was over the south edge of the lake and quickly moved to the north east side of the lake, and was out of site within 1 to 2 minutes. at the closest the object was about 1/3 to 1/2 mile away and it had the color of embers of camp fire and seemed to be maybe 50 feet in diameter. at first i dismissed it as a drown or something along those lines, but speed and distance covered with no noise made me wonder. one month later on july 2nd similar time after 1am i saw a similar orb or ball at a greater distance south of royal and was able to get a poor photo but as the distance closed and i was attempting to get a video with my cell phone it completely disappeared, and i didn't see what direction or speed it left at. i am curious if any one else as seen something along these same lines in north west iowa. it seemed to be strange that i saw something on june 2nd and then again on july 2nd????
