Just as I left the house to drive into work this morning, around 5:50am, I saw a bright greeny-blue fireball trailing debris off to the west, with an apparent position south of the moon. After a couple of seconds it exploded in a bright flash.

One other person here saw it this morning too. Anyone else notice it? I've been trying to see if there are any known suspects. At meteor entry temperature everything looks blinding white, so I wonder whether this wasn't orbital junk with fuel or something else contributing to the colour.
