(meteorobs) Observation June 24/25 2010

[Pierre Martin]

I made an attempt to hunt for some June Bootids on the evening of June  
24th.  I setup at the Pendleton Airport (GGC) and observed for over an  
hour near midnight.  It was a comfortable night with few mosquitoes.

The gibbous Moon was high up in the south, and obviously *very*  
bright.  I did my best to keep it well away from my field of view, by  
facing the northern sky.  The best area of the sky had a maximum  
limiting magnitude of 5.00.  With these bright conditions, meteor  
activity was very low.  Only a single faint sporadic was seen.  No  
June Bootids.  The nice mag -3 ISS pass overhead was just about the  
only interesting thing that happened :)

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

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
______0__+1__+2__+3__+4______AVE

SPO___0___0___0___0___1_____+4.00

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.
