We had great skies in Tulsa, OK. for the Perseids this past weekend.
Some thought they were better on Sat. night and Sunday morning.  I
counted 307 from 9:30p.m.CST Sunday night to 5:15a.m. Monday morning
from our Tulsa Astronomy Club site.  Out of the 307, 292 were Perseids,
3 Alpha Caps, 1 possible Lacertid, 5 Kappa Cgys(one was a beautiful
golden -3Mg.) and the rest were sporadic.  One thing I noticed during
the 7 plus hours of observing, there would be lulls of no activity for
as much as 10-15 minutes then you would see as many as 5 within a
minute.   By 4a.m. most of the negative meteors were falling out of the
sky to tbe west.  Also I would say 80% of the meteors went either right
down the Milky Way or one side or the other, which made sense if you
tracked the Milky way from one end to the other it came back to the
Perseid radiant.  It just seemed unusual seeing the meteors fly down the
Milky Way like a super highway.  I felt that we actually saw more
Perseids after the predicted peak time.  The highest activity I felt was
between 4a.m.-5a.m..  Many left 1-3 second trains also.
Overall it was a good shower, but not the best Perseid shower I have
seen.

Hello list,
 
Due to the extreme heat in the midwest I cancelled my vacation to SE
Kansas  
but have started
using a new location about 4.5 miles SSW of Powell Gardens in Johnson
County 
MISSOURI.
Zenithal Star there is +6.5
 
Facing NE for 3:45 of observing time from 1116-0316 local time I will  
comment quickly on the 
following, and give a more IN-DEPTH report later next week on this
session.
 
93 meteors total, 16, 24, 19 (:45 min.), & 30 in the time bins. I had 4
in 
five minutes at 1046pm prior to the main session. Of course the Perseids
were  
the 
dominant source, but had interesting notes otherwise.
 
Perseids are overall a smattering of bright ones with otherwise slightly

below average main
population index.  I had a -5, -4, -3, -2, and just a few -1 to  +1's.
Gold 
with a couple Reddish-Orange ones the vast majority on the  brighter
ones.
 
I had a few Kappa Cygnids, one slow fragmenting one from Ursa Major
early  in 
the eve., one Lacertid candidate, several Delta Aquarids (missing a
negative  
mag. one that two other observers both saw), and had  0 mag. and a -4  
beautiful Alpha Capricornids that I believe might have been the meteor
seen by  Dr. 
Eric Flescher's group at the Louisburg KS observatory, which probably
lined  
up with the K Cygnid radiant for them but was a definite Alpha
Capricornid from 
 my site further NE. (I am in Lenexa KS with my observing logs still E
of 
Lone  Jack MO currently resting and watching the mesoscale T-storm
complex in E  
Nebraska late pm on the 12th Sunday.) ANT meteors were few, I think I
had  
three.
 
Perseid highlight was near the end of the first hour when everyone was  
commenting on lack of bright ones,
and a 0 mag. followed one second later by a -4 sped thru Pegasus with
both  
leaving trains of 1.5 sec. and 6 seconds.  The -5 terminal bursting
yellow  
Perseid was I believe just after the -4 Alpha Cap at 1229am very low in
the N  
sky and if Paul Martsching was action up in Iowa would have been in the
SW sky  
for him in Iowa.
 
Summary - fairly LOW Perseid rates, with qualtiy members interspersed in
the 
show, but dimmer overall this year with the main index.
