A huge fire ball like a small moon, colors aqua, green, blue..sailed across with soft wind sound...2:am Bronx NY

My brother and I were walking home at 2:am  down a bronx street at schieffiline ave, as we were crossing the bus stop, I saw a glow over the project building, when I glanzed up I observed a huge sphere-like sailing with green and blue flames, I herd a slight soft wind sound as it traveled accross the sky very low just under the clouds, it seemed very close to the 10 floor building.. continued towards north-east direction, from where we were standing that would be going towards long Island,we observed it about a minute and half before it was covered with the clouds but there was a corona formed aqua color, there was some night car traffic, i guess some other people saw this as well..never saw anything like it again.
