(meteorobs) Observation November 5/6 2011

[Pierre Martin]

There was an error in the magnitude distribution for sporadics.   
Corrected below:

DATE: November 5/6 2011
BEGIN: 07:20 UT (02:20 EST) END: 08:30 UT (03:30 EST)

City & Province: Almonte, Ontario, CANADA
RECORDING METHOD: talking clock/tape recorder, plotting
----------------------------------------------------------

OBSERVED SHOWERS:
Andromedids (AND) - 01:26 (022) +27
Northern Taurids (NTA) - 03:35 (054) +22
Southern Taurids (STA) - 03:39 (055) +14
Eta Taurids(ETT) - 03:42 (056) +24
Orionids (ORI) - 07:11 (108) +16
Leonids (LEO) - 09:48 (147) +25
SPO (sporadics)
----------------------------------------------------------

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

PERIOD(UT)___FIELD_____Teff___LM____SPO_NTA_STA_ORI_AND_LEO

07:20-08:30__074 +07___1.12___6.30___8___4___4___0___0___0  =  16

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 more  
info, see: http://www.namnmeteors.org/guidechap2.html

MAGNITUDE DISTRIBUTIONS:

SHOWER
_____-2__-1___0__+1__+2__+3__+4__+5______AVE

SPO___0___0___0___1___0___2___2___3_____+3.75
NTA___0___0___0___0___2___2___0___0_____+2.50
STA___1___0___0___0___0___0___3___0_____+2.50

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  
(IMO definition). The above table contains the magnitudes from all  
observed meteors, and the average (last column) for showers.
