Upper and lower pillars
produced by Venus. Shinya Ueda imaged
this pillared Venus at dawn on 11th January 2005 from Osaka, Japan.
Mercury is 0.5º to the right of Venus allowing us to gauge the
total height of the pillars as about 0.4º. Mercury (magnitude
-0.3) was 20X less bright than Venus which accounts for why its pillar
was too faint to show in the photograph. ©2005

A pillar produced by a planet
is a rare event. To see one, first find a clear horizon so that the
planet can be seen when only a few degrees high and when the sun is
preferably well below the horizon. A thin layer of cirrus cloud is
needed - perhaps previously indicated by sundogs or a sun pillar at
sunset. Search for a Venus pillar with low power binoculars - but
never when the sun is visible. Move the binoculars to and fro
slightly because faint and diffuse glows then show up better. Be wary
of false sightings caused by lens reflections! |

Venus on 9th April
2002 imaged by Carol Lakomiak of Wisconsin. Carol was photographing
Comet Ikeya-Zhang when she noticed that Venus looked odd. "Without
optical aid, I saw beams of light coming from the top and the bottom
of the planet. They were more pronounced through 11x70 binoculars.
I turned the camera to the west and began to take photos ... "
This 15s, 50mm exposure might well be the first ever image of a "Venus
Pillar".
