(meteorobs) Observation April 28/29 2006

[Pierre Martin]

Hello,

Catching up on some old reports, here's my meteor observations from  
the Reserve La Verendrye of late April.  Despite the very clear and  
pristine skies, the meteor activity was unremarkable.  The first hour  
was especially slow but things finally picked up later on.  A couple  
of late-Lyrids were seen.  It was great to see the summer Milky Way  
in all of its glory rising up in the morning sky.

Clear skies,

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

PERIOD(UT)_FIELD____Teff__LM_____SPO_LYR_ANT_ETA

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.
