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

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

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.

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.
