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.
