(meteorobs) Observation June 14/15 2010

[Pierre Martin]

Here's my results for June 14/15, at Bootland Farm.  This was a really  
gorgeous night, with excellent (5/5) transparency all night long.  The  
light dome from Ottawa was one of the smallest I've ever seen from  
this location.  Dry conditions, cool and no bugs.  It was also a busy  
night with eight setups there, with several scopes and people doing  
imaging for most of the night.

I had a great and productive session with my 12.5" PortaBall  
(including terrific views of several globulars, the Turtle nebula in  
Hercules, the Swan, Eagle, Veil, Crescent nebula, M51, M82, and last  
but certainly not least... Comet McNaught (C/2009 R1).  Ivo was also  
present with his new 120mm refractor which provided several sharp  
views.  By the time I got settled for meteor observing, it was already  
late at night, with less than an hour to go before the end of  
astronomical night.  Although the sky conditions were excellent  
(LM=6.5), I saw only one sporadic in the 46 minutes that I watched.

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

PERIOD(UT)____FIELD_______Teff___LM_____SPO_ANT

06:25-07:11___18:56 +04___0.77___6.65___1___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
______0__+1__+2__+3__+4______AVE

SPO___1___0___0___0___0_____+0.00

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.
