I was outside looking at the stars and noticed that one seemed to be darting back and forth and up and down. I was standing on back step and started to walk into yard and kept watching and waiting to try and figure out if it could be an airplane. No lights visible, just looked like a star darting around. I walked further towards it and then thought I was hearing a sort of a humming sound. I went back in to get my phone to record thinking this was just too weird. When I came back out, was still there and recorded it. I made sure to keep my body and hand still and was able to record the light darting around. I went back in and about 10 min later checked and it had moved over but seemed like it had more light. I went in to get binoculars and when I looked , I saw some red,green and blue lights was just hovering and I could hear the hum again. I was more amazed with the wonder of what it could be. Was difficult to see well, but with binoculars I almost would guess it may have had a bit of triangular shape. Couldn't make it out though because of lights flickering. That was it. I was tired and went back in.
