My wife and 3 year old daughter and myself were watching the ISS in the northern sky this morning from our apartment in south MS when a orb appeared from behind a cloud. It was heading towards the ISS what seems like just a few seconds when something like lightning shot out from it but it didn't hit the ground like lightning and it didn't travel far like lightning it stayed fairly close to the space station and it had two big lightning bolts with smaller ones coming from the big ones and one went above and the other went below the space station. The orb shot off in a different direction and was gone and the space station continued on like nothing had happened. There was no sound at all and it was over a few seconds after we first noticed the orb. My wife and I look at each other and said did you see that. We were shocked to see something like this happen and we both regret not filming as we had done on previous occasions of watching the ISS. I have heard of ball lightning and I know things can appear different from one perspective to the next but we have no idea what this was so I looked on the internet and couldn't find anything. This is when and where it happened. 5:37 to 5:40 July 24 2016 in South Mississippi looking at the northern sky about 30 degrees above the horizon.
