I was attending a cow party to celebrate the end of the summer. It
was out of town at a staff's farm (near Shawville) with clear
horizons, so I took advantage of this event to watch for any possible
early Aurigids before dawn. Despite the gibbous Moon, the
transparency was good, which allowed LM=5.3.
While setting up, I glanced up and casually observed one probable
AUR! This gave me some hope that something might be going on
already, but in over one hour TEFF, none were seen. (The AUR peak
had been predicted to be a very brief burst of activity for the west-
coast (which is exactly what happened), so I did not expect anything
- but I was curious and wanting to keep an eye on them anyway ;0))
Overall activity was in fact dreadfully slow with just four
sporadics. Other possible shower sources were dis-regarded this
morning due to the bright moon in the way.

OBSERVING PERIODS: 0 = none seen; / = shower not observed
PERIOD(UT)___FIELD____Teff____F______LM___SPO__AUR

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 not spent
looking at the sky). The 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______AVE
SPO____1___1___1___0___1_____+1.75
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.

SKY OBSCURED (FOV) (UT): None
