Bright light in sky.

Shortly after pulling onto Main Street I looked up to see a bright light at first I thought it looked like possibly a helicopter with it’s search light on and it was moving pretty fast from right to left. After pulling onto Horton Avenue I realized this was to high up to be a helicopter with a search light on. The craft was still moving right to left and the light was on the right so on the back. The light was extremely bright for how high up it was, I’d say it had to be as high as a normal passenger plane would fly. The light shinning in back which was a white light looked dusty. After pulling onto Horton Ave and watching it for another 15-30secs the light turned off (it did not fad out) but you could still see the craft moving and it looked like it was leaving a dust behind. It moved quickly behind the tree line and that’s it. The object was not over head but maybe a few miles away, where I was looking it was towards the Cheshire/Hamden line but it’s hard to decipher how far it was from my location. But it was bright and large enough to see where I was. This did not look like a shooting star, green fire ball or comet. This was a craft of some kind.
