Venus Transit 2012
Telescopes will be set up on the front lawn of
the Plymouth Public Library a few hours before sunset on Tuesday June 5 to view
the last time in more than a century that Venus will appear to cross the face
of the Sun. The last time this event happened was at sunrise on Jun 4, 2004.
The next pair of this event will not be until 2117.
A few dozen people witness the 2004 event from
the Plymouth waterfront near the Mayflower. much of the transit event, as it is
called, was visible after the fog cleared about an hour after sunrise. Many of
the people at that event signed a book to indicate their presence at this
event. The same book will be available at this event on Tuesday so the same
people can record their presence at this event. This book will be saved for the
2117 event for descendants to check their families' continuing participation.
Telescopes will be set up in the front lawn of
the library on South Street in Plymouth at 5:30 PM. Venus starts to move onto
the face of the Sun just after 6 PM. It does not leave the face of the Sun
until after sunset. The telescopes will have the appropriate solar filters.
Other filters will be available for people to view the Sun without a telescope
(the dot of Venus will be visible without the aid of a telescope).
Observing the Sun Information:
Use some kind of pinhole projection box, #14 welder's glass or mylar solar viewing glasses (see below) – no matter what you use (except for the projection method) do not stare at the Sun for a long time and DO NOT use sunglasses, smoked glass or over-exposed X-ray film! These methods are recommended for Mercury or Venus Transits and Solar Eclipses. Near solar maximum (2012-14?) there may be large sunspots that are visible to unaided eyes – these methods can be employed to see these.
