Comet C/2014 Q2 Lovejoy 28-12-14
Sorry about taking so long to get back to you. Off on holidays with limited internet access.
Anyway, what you saw was a fireball, a very bright meteor. They are beautiful and relatively rare. Fireball seeing, being in the upper atmosphere, is very location dependent, you may have been to only people in the world to see your respective meteors.
The comet itself is dim, and its movement can only be discerned over a period of several hours when using your unaided eyes.
