(meteorobs) Observation November 12/13 2009

[Pierre Martin]

Hello,

I was out this past Thursday for a short early evening session at the  
GGC (Gatineau Gliding Club) site (about 45 min east of the city).  The  
sky was clear and crisp, and a fairly comfortable temp of -2C (28F)  
but it was not without a significant humidity around the horizons and  
a layer of frost near the end.  I could only observe for an hour, and  
as expected, meteor activity was quite low.  Three members of the  
North Taurids were seen, but only one sporadic.  The brightest meteor  
was a long mag +1 Taurid that I saw by chance, far out of my field of  
view, as I was re-adjusting my sleeping bag.

The weather is looking great here for the Leonids, with clear skies  
expected all night. Best of luck to everyone else!!

Notes: The first column (Period UT) refers to observing periods, 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) Teff is  
simply the total time during the observing session spent actually  
watching the sky. Breaks and/or dead time are not included in the  
reported Teff. It is reported in decimal format such that a 60 minute  
observing session would be reported as Teff = 1.00. The column F is a  
correction when obstructions such as clouds block portions of the  
field of view (1.00 = 100% clear skies). The column (LM) is the  
average naked eye limiting magnitude seen.  All following columns  
indicate the number of meteors for each shower observed.  For more

______1__+2__+3__+4__+5______AVE

SPO___0___1___0___0___0_____+2.00
NTA___1___0___1___0___1_____+3.00

Notes: 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  
(IMO definition). The above table contains the magnitudes from all  
observed meteors, and the average (last column) for showers.
