Greetings again all,
     I ventured down once again to Matanzas Inlet for two more hours of
pre-max Perseid observations.  This time, the cirrus clouds were gone and
the sky was blissfully clear.  My results for each of the two hours was
almost identical!

Here's the data:

Observed for radiants:

CAP - alpha Capricornids
ERI - eta Eridanids
ANT - Anthelions
PER - Perseids
SDA: South delta Aquariids
PAU - Piscids Austrinids
NDA: North delta Aquariids
KCG: kappa Cygnids
BPE - beta Perseids

Session One:
August 3/ 2016, observer: Paul Jones, Location: Location: North Bank of
Matanzas Inlet, Florida, Lat: 29.75N, Log: 81.24W (approximately 18 miles
south of St. Augustine, Florida). 25% cirrus cloud interference, Facing:
west

0325 - 0425 EDT (0725 - 0825 UT), Teff: 1.0 hour, No breaks
14 PER: +1(2), +2(5), +3(3), +4(2), +5(2)
6 SDA:  +1, +2, +3(3), +5
1 NDA: +3
1 CAP: +3
1 ERI: +3
8 SPO: +2, +3. +4(4), +5(2)
31 total meteors

7 of the 31 meteors (6 PERs and 1 SDA) left trains. Yellow and blue tints
were seen in the brighter PERs and the SDAs.


Session Two:

August 3/4, 2016 Observer: Paul Jones, Location: North Bank of Matanzas
Inlet, Florida, Lat: 29.75N, Log: 81.24W (approximately 18 miles south of
St. Augustine, Florida).



0425 – 0525 EDT (0825 – 0925 UT) Teff: 1.0 hour, No breaks, LM: 6.9, Clear,
except for some very slight haze near the horizons, facing: west


14 PER: +2(4), +3(8), +5(2)

5 SDA: +2, +3(2), +4, +5

1 NDA: +4

2 ERI: +3, +4

9 SPO: +1, +2, +3(3), +4(4)

31 total meteors


9 of the 31 meteors left trains (7 PERs, 1 SDA and 1 SPO), a couple of the
PERs were bluish and a couple were yellowish.


I was struck by how almost identical the two hours turned out in terms of
the numbers.  They were almost mirror images of one another!  The biggest
difference in the meteors of all types this morning was that they were so
much fainter than the previous morning - across the board.


I was lucky the skies were so good or I would not have seen many of them
through yesterday's cirrus cloud invasion...;o).


More later, Paul J in North Florida
