I definitely agree with Bill. I really wasn't expecting too much as the
peak was suppose to be in broad twilight for Tulsa, OK USA but we had
some impressive Aurigids. I only saw 10, but everyone of them was
impressive and bright. In fact two of them I would consider daytime
meteors.

NOTES:
Bright waning gibbous moon through duration of count. Looked northeast
and used ballcap to keep moon out of line of sight.
Glad to have seen some Aurigids. The second fireball produced one of
the longest lasting persistent trains that I have seen in quite some
time.
