A short late-night meteor session under nice dark skies.  The  
Perseids was the more active of the shower sources...

Clear skies,

OBSERVING PERIODS: 0 = none seen;  / = shower not observed

0435-0550__0020+46__1.24__6.50___10___5___1___1___1___1___0  =  19

Note: The first column (Period UT) refers to observing periods broken  
down as close as possible to one hour of true observing, in Universal  
Time. The second column (Field) is the area in in the sky where I  
centered my field of view. The third column (TEFF) represents  
effective observing time (corrected for breaks or any time I did not  
spent looking at the sky).  The next column (LM) is the average naked  
eye limiting magnitude, determined by triangle star counts. All  
following columns indicate the number of meteors for each shower  
observed.

MAGNITUDE DISTRIBUTIONS:

SPO____1___1___2___2___3___1_____+3.80

ANT____0___0___0___1___0___0_____+4.00
SDA____0___0___0___1___0___0_____+4.00

Note: Magnitude -8 is comparable to a quarter moon, magnitude -4 with  
the planet Venus, magnitude -1 with the brightest star Sirius,  
magnitude +2 to +3 with most average naked eye stars and magnitude +6  
to +7 are the faintest stars the naked eye can see under typical dark  
conditions. A meteor of at least magnitude -3 is considered a  
fireball. The above table contains the magnitudes from all observed  
meteors, and the average (last column) for showers.
