(meteorobs) Observation May 4/5 2006

[Pierre Martin]

On the morning of May 5, I enjoyed some nice meteor observing at the  
Boundary road site in company of Chris Cloutier (who was trying his  
luck at photographing meteors).  The meteor rates were quite high and  
it was a productive session leading up to morning twilight.  Although  
sporadics were the main activity, a few speedy Eta Aquarids were seen  
as well as one candidate for Eta Lyrid (IAA).

Clear skies,

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:

ETA____1___2___0___1___0_____+2.25
ETA____0___0___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.
