Moving star grows extremely bright then fades away.I had fallen asleep watching TV on the couch and woke up at about 4 AM. I got ready for bed, my wife was sleeping already, and I went outside to smoke a cigarette on my porch.I sat down, not really paying attention to the sky, when all of a sudden out of the corner of my eye I saw what appeared to be a star moving. I had seen these before but this time the sighting only lasted about 4 to 5 seconds. The star got extremely bright, brighter than any star in the sky, as it began to move from left to right and slightly downwards. The light that was emitted was a bright white light, the same color as the stars. As soon as it appeared it disappeared, losing all brightness and finally disappeared. I waited about a minute with my camera phone handy in case it decided to reappear again but it never did.I've seen moving stars here in Puerto Rico before, about 4 to 5 times in a 4 year period But I was always able to relocate the moving star and was able to follow its trajectory with the naked eye, observing them as they grew bright white and then faded out about every 15 seconds approximately, eventually losing track of them as they continued on their path. This time though the bright white light was even brighter than the previous sightings of moving stars and the whole sighting only lasted about 4 to 5 seconds. Afterwards, I could not relocate the moving star again.
