(meteorobs) Observation April 12/13 2010

[Pierre Martin]

I enjoyed my first meteor session of the year at Bootland Farm.  Had  
the company of four other people with setups there.  I cannot recall  
ever seeing this site dry and fully accessible so early in the year -  
a real treat!  I was setup for just one hour of meteor observing,  
prior to midnight, as work the next day prevented me from staying any  
later.  Nice night, cool, comfortable, no bugs and lots of spring  
peepers in the distance.

As for meteors, only five sporadics.

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

PERIOD(UT)____FIELD_______Teff___LM_____SPO_ANT

02:50-03:55___12:11 +06___1.03___6.30____5___0

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
______+3__+4______AVE

SPO____2___3_____+3.60

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.
