A group of 5 or 6 of us saw it and watched in amazement... we couldn't figure out what it was... it looked like a firework from the neighbor's yard but we couldn't figure out why it was silent or why it was travelling parallel to the earth...

Remarks
we thought it was a firework coming from neighbors.... it moved slowly from right to left and after a few seconds had a little explosion that may have contained some red or blue - looked just like a firework without any noise and at a parallel angle to the earth...
