david asked my wife noticed something odd the nearly full moon was about NUMBER degrees above the horizon there was a notable glow on the horizon except under the moon the moon seemed to be in a column of darkness that was about three times the apparent width of the moon we could see the column over its entire length as a strip of sky darker than the sky around it any of you ever see this do you have any idea what could have caused it i suspect it s due to some pecularity of the visual system but have no clear idea i m surprised to not find this phenomenon in corlis i could have sworn i saw it there he does have the somewhat similar dark sky between a rainbow and a secondary bow i personally have seen a rainbow enclosing a semi circle of darker sky i know i ve read about pillars under the sun and moon elsewhere but i can t recall if they were reportedly dark or bright i do know these sorts of things are supposed to be quirks of optics not of the visual system i m sorry i haven t got any answers but a search through some books on atmospheric optics ought to turn a few hints up bill william jacobs freelance unemployed person yahoo groups sponsor NUMBER dvds free s p join now URL to unsubscribe from this group send an email to forteana unsubscribe URL your use of yahoo groups is subject to URL
