Hello.
>From West Orange, NJ through a small patch visible between trees, a house
and paranoid neighbors all night house lights I saw one very bright 2 sec.
white with trail travelling SW @ 3:10AM. Watched for @2more hours but saw
nothing big enough to cut through the haze.
Next year I swear I'm going somewhere dark!

I was out most of last night observing 0345-0645 and 0700-1015 UT. I saw
no Perseid fireballs and fewer negative magnitude Perseids than the
previous morning.
The parking lot lights at the Story County Conservation Center at
McFarland Park go off at 10:45 CDST. The LM was a little better than yesterday.
On drive home saw evidence of horizon haze up to 3 degrees, but still not
bad for Iowa in summer. I deployed a black umbrella to block the bright Moon
light.
The session got off to a bad start. I saw two Perseids right away, then
it was a half hour before I saw another meteor. There were several other
long lulls in which no Perseids were seen. It was nearly two hours before I
saw the first negative magnitude Perseid.
The brightest meteor of the session was a - 5 yellow Antihelion that ended
near Capella. The next brightest meteor was a - 4 yellow Kappa Cygnid.
The brightest Perseid was - 3. The brightest ATR was - 2. No apparent
SDA's or ERI's. Trains were more apparent than yesterday morning due to
slightly better LM.

Hopefully good!!!
The last night there were a few video meteors. More video Perseids the
night before that between 10 and 11 including a -4/ -5.

I can not confirm this 'enjoyable PER activity' between the period 01.12 -
03.12 UT. No fireballs and not so many negative magnitudes...
30 Perseids during this 2 hour watch...
Long trains and good luck for the main maximum!

Because of the bright Moon light train durations were generally very
brief. Report later.

I've had two observing sessions since my last report July 29. Went out to
the Blackfoot site at Beaver Hills Dark Sky Preserve after moonset on the
morning of Aug 6, and snatched a couple of hours from the city limits on the
morning of Aug 12 under bright supermoonlight. Had planned to also go out
on the 12/13 for the post-peak show with Ross Sinclair, but we were totally
clouded out. Fortunately, I had gotten my "contingency sample" on the
11/12, making this my 27th straight year of observing Perseids within 24 hours
plus or minus of the peak.
That occasion had an auspicious beginning when I saw a beautiful 4-second
kappa Cygnid literally a couple of seconds after I left my house as I was
walking down the porch steps towards the car. With the bright Moon rampant
in the south, I headed due north of my home, got to just outside the city
limits (about 12 km from my home rather than the usual 55), and found an
isolated spot on an E-W road with zero artificial light trespass of any
description. I settled in the shrubbery on the south side of the road to block the
moon and most of the light dome of Edmonton, and concentrated on the
northern half of the sky, with Polaris being in the centre of my chosen field of
view. Even so, the limiting magnitude was pretty poor at just 4.3, as I
could *barely* see the arc of 3 stars of about that magnitude between Polaris
and Kochab in Ursa Minor.
Not surprisingly, Perseid counts were not great, some 29 seen in two hours
Teff, along with 3 kappa Cygnids and 5 sporadics (a couple of which were
from southern, but otherwise unidentifiable, radiants). Of those 37 meteors,
11 were of negative magnitude, topped by a brilliant silvery-white Perseid
of mag -6 that dropped straight down from the radiant, leaving a fading
train for 7-8 seconds. Colourful meteors were very few and far between, while
trains were very brief, both no doubt affected by the brilliant moonlight.
Unlike my previous session at Blackfoot where it was so quiet at times I
could hear my own pulse, this spot was closer to "civilization" so there was
a constant hum of traffic, dogs barking, etc. I was unable to find a good
station with "clean static" for radio monitoring, so I opted to put in my
ear buds and listen to some contemplative music. The obvious choice from my
iPhone collection was an album by the great American jazz trumpeter Jon
Hassell, entitled "Last Night the Moon Came Dropping Its Clothes in the
Street". An appropriate title for the night after the much-hyped "Supermoon"!
It's based on a poem by the 13th century Sufi mystic Jalaluddin Rumi that
begins:
Last night the moon came dropping its clothes in the street
I took it as a sign to start singing
Falling up into the bowl of sky
Somehow seemed appropriate to the task (and the pleasure) at hand.

The Perseid main maximum night was partially clear in Ronse, Western
Belgium. Some long observing periods were spoiled by cirrus and other middle
lower cloud fields. Despite the cloudy periods, I was present on the
observing field between 21.15 (August 12) - 03.15 UT (August 13). Only 4.25 hours
of the 6.00 observing hours were useful for data reduction. In grand total I
observed 153 meteors including 133 Perseids. Hourly counts topped at 39
PER/ hour for the period 01.00 - 02.00 UT with a Lm around 5.40. I looked
into northern direction. This Perseid display was a good mix between weak and
bright meteors. I was able to see 4 fireballs (-7, -6, -5 en one -4). Most
fireballs were captured by several all sky systems at Zeeland (the
Netherlands) and Oostduinkerke (Belgium).
August 10-11 (not observed) and 11-12 was also (partially) clear. August
13-14 was clouded out.
I collected also a mass of visual data during the moonless period from end
July - begin August: my observing nights were: July 23-24, 24-25
(Belgium) and July 26-27, 27-28, 29-30, 30-31, 31- August 01, 04-05, 05-06, 06-07,
07-08 (from Revest du Bion, dep. Hautes Alpes de Haute Provence in France.
I know what to do ;-)
Clear Skies!
