Below are detailed follow-ups to my two previous summary GEM reports.

December 12/13 (December 13 UTC)

Location: Bastrop County, Texas - Lat. 30.33 North, Long. 97.24 West
Weather: Very pretty - clear, calm, chilly (Ending temp. was 32F/0C.)
Obstruction: 1% or less (treetop off to my left, peripheral vision)
Observing focus in sky: altitude 60, azimuth 120

LM +5.5 using faintest stars

UTC Time.  Each time period is 5 minutes or 0.083 hour.
05:30-35 - GEM 2, Others 1 (GEM +1, 0)
05:36-41 - GEM 2, Others 1 (GEM -1, +1)
05:42-47 - GEM 3, Others 3 (GEM -1, +1, 0)
05:48-53 - GEM 3, Others 2 (GEM +5, +4, +1)
05:54-59 - GEM 1, Others 0 (GEM +3)
06:00-05 - GEM 6, Others 1 (GEM +4, +3, -1, +2, +3, 0)
06:06-11 - GEM 5, Others 1 (GEM +3, +4, +2, 0, +3)
06:12-17 - GEM 3, Others 1 (GEM +4, +1, +5)
06:18-23 - GEM 4, Others 2 (GEM +4, +2, +3, +4)
06:24-29 - GEM 2, Others 2 (GEM +1, +4)
06:30-35 - GEM 2, Others 0 (GEM +2, +5)
06:36-41 - GEM 3, Others 0 (GEM +4, +4, +2)
06:42-47 - GEM 1, Others 2 (GEM +2)
06:48-53 - GEM 1, Others 0 (GEM +1)
06:54-59 - GEM 2, Others 0 (GEM +3, +3)
07:00-05 - GEM 7, Others 0 (GEM +3, +3, 0, +3, +2, +1, 0)
07:06-11 - GEM 4, Others 1 (GEM +1, +5, +2, +3)
07:12-17 - GEM 1, Others 0 (GEM +4)

Teff = 90 minutes (1.5 hour) - GEM = 52, Others = 17

The first meteor was a -1 sporadic earth-grazer that crossed low
across the north from near Leo, passed near Polaris, and went on
to the northwest, leaving a very long train.  (Maybe it was a
Coma Berenicid?)

Just about the brightest one that I saw, 7:06-11, ended only a
degree or two above the horizon but lit up the sky and ground!
(A fellow observer looking in the opposite direction saw its
light.)

The weather tonight was turning cloudy and foggy, so no go.
