Kenneth and All,
Your description of the path seems to indicate a Taurid meteor. Taurids
though, are not swift meteors with a maximum angular velocity of only 17
degrees per second. At that time of night my rough calculations show the
maximum angular velocity of ANY meteor to be near 23 degrees per second.
This is fairly swift when compared to the average angular velocity of 5-10
degrees per second of meteors seen that time of night. Meteors seen just
before dawn can approach 40 degrees per second.
If your meteor was indeed 12 degrees long then its duration could be no less
than one half second. My feeling is that the actual length was shorter
(estimating true lengths is not easy and easily overestimated!) and that the
duration of the meteor was a quarter second or less. This adds up to be a
I hope this helps!
