(meteorobs) Observation May 18/19 2007 (Bootland Farm)

[Pierre Martin]

Hello all,

I've never been so late with my observing reports!  It seems that  
I've been able to get in a fair amount of observing this summer, but  
I could never get around to the reports.  Where did the time go?  I  
suppose that it's always better to send them in late than never  :0)

Going way back to the morning of May 19, I enjoyed a short one hour  
pre-dawn session at Bootland Farm, along with some first views of the  
summer Milky Way with my 80mm Megrez refractor.  I recall this night  
being fairly decent, but with some haze near the horizons.  It was  
also very noisy... lots of frogs squeaking and squawking from every  
direction!  The cool air and lack of mosquitoes for that time of the  
year made it an enjoyable session.

Observed meteors for one hour, and the activity was a rather routine  
drizzle of sporadics.  No shower activity was noted.  The brightest  
meteor was a magnitude -1, yellow streak that crossed Aquila.

Clear skies,

Pierre Martin

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

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
______-1___0__+1__+2__+3__+4__+5______AVE

SPO____1___0___0___2___1___4___1_____+3.00

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.
