(meteorobs) Observation April 13/14 2010

[Pierre Martin]

I went to Bootland Farm for the second night in a row.  There was  
three setups when I got there, including Bart with his cool mobile  
observatory/MallinCam setup.  Nice decent skies overhead, without a  
hint of any breeze or clouds.

I observed for just one hour prior to midnight.  Not too surprisingly  
for this time of the year, I recorded just four sporadics and one  
antihelion.

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

PERIOD(UT)____FIELD_______Teff___LM_____SPO_ANT

02:35-03:40___11:34 +10___1.03___6.45____4___1

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 (LM)  
is the average naked eye limiting magnitude seen.  All following  
columns indicate the number of meteors for each shower observed.  For

MAGNITUDE DISTRIBUTIONS:

SHOWER
______+1__+2__+3__+4______AVE

SPO____0___2___0___2_____+3.00
ANT____1___0___0___0_____+1.00

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.
