(meteorobs) Observation October 6/7 2005

[Pierre Martin]

On the following evening (October 6), I observed from closer to home 
(Boundary road) for a couple hours.  The skies conditions were not 
ideal.  The transparency was poor, and thin clouds moved quickly in and 
out throughout the session.  I was forced to take an unexpected long 
break as I waited for the skies to improve again.  But the "sucker 
holes" were often large enough to allow observations without cloud 
interferences.

As a result, the meteor rates were low.  The first hour was very slow 
with only a single anthelion meteor.

Fortunately, the second hour recovered with 9 meteors.  Nothing special 
was seen.  The Draconids were again silent.  However, two fast meteors 
were plotted that aligned to a point near Andromeda and Pegasus.  This 
seemed near the area I had noticed some activity on the previous 
evening.

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

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____3___4___1_____+3.75
ANT____0___1___0_____+4.00
DAU____0___1___0_____+4.00

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.
