OBSERVING PERIODS: 0 = none seen; / = shower not observed
PERIOD(UT)__FIELD____Teff__LM____SPO_DAU_SPI_KAQ_napx_sapx
0645-0755___0145+09__1.00__6.80__11___3___1___0____2____1

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). One hour = 1.00 teff. The fourth column
(LM) is the average naked eye limitimg magnitude, determined by
triangle star counts. All following columns indicate the number of
meteors for each shower observed.

MAGNITUDE DISTRIBUTIONS:
SHOWER
SPO: +1(1) +2(4) +3(8) +4(4) +5(8) +6(2) AVE: +3.74
DAU: +1(0) +2(1) +3(1) +4(1) +5(1) +6(0) AVE: +3.50
SPI: +1(0) +2(0) +3(0) +4(0) +5(0) +6(1) AVE: +6.0
Note: Magnitude scale is to determine the brightness of sky objects.
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.
------------------------
SKY OBSCURED: None
Corresponding F value: 1.00
------------------------
Dead time:
- 9 minutes used for breaks.
- 3.98 minutes used for plots.
Breaks (UT): 7:00-7:01, 7:07-7:12, 7:45 (3min)
