Perhaps the SPA has a more experienced audience compared to the AMS, 
especially in the British Isles. We would not expect the general public to be 
highly accurate with magnitude estimates. This is one reason we listed magnitude 
estimates in at least two step increments. Still, a majority of contributors 
will choose an estimate of "brighter than the full moon" regards of the true 
brightness.

 
 
 
A week ago, when the 4-day old moon was in conjunction with Venus, I 
posed a question to a number of people: "Which appears brighter to you, the 
moon or Venus?"  Everyone who I asked said the same thing: "Venus."  
But on that particular night, the moon was actually brighter by some 3.5 
magnitudes (a brightness ratio 25 times that of Venus).  Of course, 
the reason that Venus was the overwhelming favorite was because it appears to 
the eye as a dazzling point, whereas the crescent moon's light was spread out 
over a half degree of sky.
