The following meteor has a very high angular velocity, in fact it is the 2nd fastest meteor I have ever recorded, that's out of 1388 meteors. It's also very bright, 9th brightest. The brightness is partly due to its high velocity. To give you an idea, the Leonids are the fastest meteors with an average velocity of 70 km/s 
. The fastest Leonid I captured had an angular velocity of 28.5 deg/s. This meteor has an AV of 35.4, that's fast.

Because of this I reported it to Tolis Christou at the Armagh observatory. Luckily they have also recorded the same meteor so we should be able to determine a pretty accurate velocity.
A hyperbolic meteor is one which was not in orbit around the sun and has therefore come from outside the solar system
But don't get too excited, if the meteor observed was at an unusually low altitude say 80km up then it is not hyperbolic. But thanks to Armagh observatory we have a two camera system and are able to determine the height.

for further discussion with the Japanese observers
