Hi all,

I finally got around in doing my end-of-summer meteor reports.  Better 
late than never! ;0)

This session was on the peak morning of the Alpha Aurigids (AUR).  
Activity seemed very normal, while I observed during the last hour 
before dawn.  AUR were mildly active with three faint meteors, however 
a number of fairly bright sporadics appeared.  The highlight was a long 
25 degrees mag +1 sporadic with 1 sec train.

Clear skies,

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

*Note: SIA/ANT activity combined together

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:

SHOWER
_______0__+1__+2__+3__+4__+5_____AVE

SPO____1___3___4___1___0___0_____+1.55
AUR____0___0___0___0___2___1_____+4.33
ERI____0___0___0___0___0___1_____+5.00

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.
