I was out east of Hickman, NE at Wagon Train Lake near the dam, on the north east part, closest to the parking lot, set up to do a little fishing and take pictures of the sunset. (I have included a map of the lake; where the little yellow bubble is at the bottom of the map is where I was.) As the sunset wasn't all that spectacular, I turned my attention to the June full moon. I took around 30 pictures in all, throughout the moon's rise, facing easterly from the south end of the lake. I did not look at the pictures until earlier today. I have not tried to crop anything, or filter it or do anything with the images. It may be a plane, but the pictures were taken seconds apart and were on a photo burst setting, so I really don't think that's what it is.
