Here's my report for Friday's memorable session at Beckwith Park 
(located south-west of Ottawa, On)... About halfway in the night, I 
took a break from deep sky viewing and did about an hours worth of 
meteor observing.  As expected for this time of the year, the meteor 
activity was pretty low with just one (nice!) Virginid and four 
sporadics.  It was nice to just sit back and "look up" again.  Meteor 
data follows below...

Clear skies,

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


0525-0635__1317+13__1.06__6.30____1___4  =  5

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.




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.


F = 1.00


Dead time: 6 min total (plotting, breaks)

Breaks (UT): None
