Carribean SeaI was on a cruise in the Bahamas with my family and met a kid that I befriended that I stayed up with till about 4 every morning just talking about a bunch of random stuff. One clear pitch black night ((we were in the middle of the Carribean Sea)) night, I noticed a round ((not like airplanes with 4-5 lights))bright yellowish-white circle and saw it out of the corner of my eye and alerted the other kid. I stared at it for about 30 seconds, then it dissapeared. It re-emerged 10 seconds later, and we saw it for about 5 seconds then it was gone and didnt come back again.((NUFORC Note: Date is approximate. PD))
