I went to a diner in bethpage, ny,. i went with 2 others, they entered diner, i stayed outside for a couple of minutes, when i saw the object on my left side in the sky. thought was a plane or chopper, but i observed a bowling ball shaped object kind of hovering or moving slowly approaching from my left(east to west) was amazed, took a few steps towards the direction it was coming from to get better look. i looked for wings or prop. was none.I waved and it started moving back towards se, instead of hovering or moving slightly west.It then also ascended quickly into the moderate decked clouds and disappeared. i was kind of awe struck and very impressed..Not the first time i`ve seen unusual stuff, at all.
