(meteorobs) Observation October 8/9 2003
Here's my meteor report for the evening of October 8. I went out to
the Casselman site to verify for any Giacobinid activity despite the
Full Moon. I watched for almost four hours teff until just after local
midnight. Unfortunately, the Full Moon really hampered any meteor
activity at all. It took well over an hour to see my first meteor.
The Giacobinids were completely silent, and a total of only four
sporadics were recorded. Near the end, I was glad to have had a good
dose of coffee to keep me awake for such a slow evening!
Looking forward to higher rates with the Orionids.
Clear skies!

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 fourth column (F) is a value for obstructions in the field of
view such as clouds (1.00 = 100% clear skies). The next 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.

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 (FOV): none

Dead time: 2.16 min (breaks).
Breaks (UT): 0:29 (60sec), 0:37 (40sec), 2:14 (30sec)
