Here is my Individual Preliminary Report.
4 hours of observing Leonids under 5.6 to 5.7 magnitude Skies 90 degrees 
11 minutes 19" west longitude + 30 degrees|  46'|  32" latitude. 
742 Leonids were counted on tape.
 
Long Earth Grazers from 11:30 CST till 12:30 CST. They were mostly 1st magnitude, 
flying in parallel from east to west.

From 7 UT to 8 UT hourly count was 36 Leonids|  (1 to 2 am local)
From 8 UT to 9 UT hourly count was 90 Leonids|  (2-3 am local)
From 9 UT to 10 UT hourly count was 220 leonids (3 to 4 am local)
From 10UT to 10:30 Ut HALF HOUR count 241 Leonids (4 - 4:30 am local) 
(see below for minute counts)
From 10:30 to 10:48 UT 18 minute Count 155 Leonids (4:30 to 4:48 local)

Count from then on was ceased due to strong Leonid activity, no matter what 
direction one looked they were falling, despite increasing astronomical twilight 
to the east. One could not really make an accurate estimate. I saw 10 at 
once looking west towards Orion where the sky was still dark.
While others were seeing similar activity looking north, or south. The zodiacal cone
was now going through Leo.

After 11 UT (5 am) the activity slowed somewhat due to increasing sky
brightness because of twilight. I continued to see Leonids while the sky was 
turning blue, as did others 7 seen of 1st magnitude at 5:01 am, and still strong 
activity at 5:04 despite haze and high cirrus now overhead I saw 6 more of 0 to 
1st magnitude.

Many fireballs, though the amount did not approach the 1998 fireballs which 
I saw from west Texas under 6.8 magnitude skies.|  There were several that 
were of the -8 category, and at least 2 bolides, which split and left| enduring 
trains( though none of the 20 minute| trains we saw in 1998). Some lit up the 
ground like strobe lights. A great mix of fireballs, and bright meteors with a 
lesser number of fainter 3-4th magnitude, but mostly -1 to 2nd magnitude. 
A number of J- shaped trains,|  both right side up and up side down.

10:12 - 10:14 - 23 Leonids
10:14 - 10:15 - 5 Leonids
10:16 - 10:18 - 16 Leonids
10:18 - 10:20 - 24 Leonids
10:24 - 10:27 - 40 Leonids
10:27- 10:29 - 12 Leonids
10:29 -10:30 - 12 Leonids
10:30 - 10:31|  9 Leonids
10:31-10:33 - 17 Leo
10:33-10:35 - 28 Leo
10:32-10:33 - 17 Leo
10:33-10:35 - 28 Leo
10:35-10:36 - 6 Leo
10:36 - 10:37 5 Leo
10:37 - 10:39 24 Leo

The excitement was so apparent on my tape as activity increased with bursts 
of 4 to 6 at once, or maybe more, from about 10:21 UT.|  A beautiful burst of 
6 at once out of the radiant at 10:23 UT,|  that had for a second or two had
trains that made the radiant appear as a sunburst, or should I say star burst.
The peak seemed to occur near 10:24 UT or so when this burst occured.

It was so apparent that activity had increased dramatically at that point, 
it seemed to me to be quite a flurry, but not sustained bursts. Spits and 
flurries of 4 to 6 at once, then slowing down to 1 or 2 then up again.
 
The skies were not perfect, but an honest 5.7 magnitude at 50 degrees elevation, 
as haze rolled in from the east, high thin cirrus type, and obscured about 25 
degrees at times, keeping the lower fainter meteors from being see, but after
the clouds of Texas......If you want a population breakdown I can provide it. 
Or more detailed breakdown.

3.57 hours of observing Leonids under 5.6 to 5.7 magnitude Skies, looking 
south at 50 degrees elevation, my observing angle. Location: 90 degrees 
1l' 19"| west longitude + 30 degrees|  46'|  32" latitude.794 Leonids were 
counted on tape. I was facing due south, about 50 degrees high.Leonids 
falling while the sky was turning blue deep into nautical twilight, as did others. 
Seven seen of 1st magnitude at 5:01 am and 15 total in this one minute, 
and still strong activity at 5:05 despite haze and high cirrus now overhead 
that came in slowly from the east in the last 1/2 hour, I saw 6more of 0 
to 1st magnitude. Between 11 UT (5am) and 11:05 UT (5:05am) I counted 
40 in 5 minutes. Many fireballs, though the amount of fireballs did not approach 
the 1998 fireballs which I saw from west Texas under 6.8 magnitude skies.  
There were several that were of the -8 category ( and at least 3 bolides, which 
split and left enduring trains( a bolide at 1:45 am of -8 through Cass left a wake
visible for 10 minutes, a|  - 4 blue bolide that exploded into pieces due
west at 2:01 am,|  left a train visible for several minutes). (None  of these
fireballs, left the 20 minute trains we saw in 1998.) One at 3:06 am lit up
the ground like a strobe light, then seconds later, a -5 left a beautiful
train.|  One at 3:51 am,|  which was a -8, lit up the ground as it blew into 2
pieces. A great mix of fireballs, several bolides, and bright meteors with a
number of fainter 3-4th magnitude, but average of mostly -1 to 2nd
magnitude. A number of J shaped trains,|  both right side up and up side
down.

Below is count from 1 am to 5:05 am local time

Obscuration of horizon 25 degrees (treeline) I was facing south looking 
about 50 degrees elevation.

The excitement was so apparent as activity increased with bursts of 4 to 6

onceout of the radiant at 10:23 UT,|  that|  for a second or two had trains that

it was so apparent that activity had increased dramatically at that point,

The skies were not perfect, but an honest 5.7 magnitude at 50 degrees
elevation was very consistent, we had some haze which rolled in from the
east, high thin cirrus type, and obscured about 25 degrees at times near the
horizon, keeping the lower fainter meteors|  from being seen, if they were
indeed there.
