Скачать или смотреть Wobbles of a 5.5meter stationary pendulum recorded during the August 11, 1999 solar eclipse

Vertical oscillations shown by a stationary pendulum during the 1999 August 11 solar eclipse. What is seen here is the outermost circles going off and on focus a few times. This is a bottom view of the pendulum's bob and the circles are drawn on its bottom face. The cross is a reference solid with the environment (it is a transparent template). Dimensional reference: inner circles are spaced 0.5mm. Note that the timer shows UT+2, which was local daylight saving time.
You might have a look at http://xoomer.virgilio.it/iovane/on_o... -. where you will find the following note too:
If you are here, probably you come from reading my article in the Hector Munera's book "Should the laws of gravitation be reconsidered?" being published by Apeiron, Montreal. This page has been created to satisfy reference No. [17] (no movies can be included in a book !).

Please wait until the movie downloads. Might require a plug-in in your browser. Alternatively look at http://www.youtube.com/eclipseshots#p... .
This is a 14 seconds AVI movie, 25 frames per seconds, size about 5 MBytes. The timer shows local summer time (UT+2) and for UT you will have to subtract 2 hours. The movie starts at 09:44:45 UT (timer 11:44:45) and the wobble starts at 09:44:52 UT.
This is wobble "e", as per the article in the above mentioned book.
In order to identify the vibrations easily, look at the outer circles near the left top first. Reload the page to view again.
This movie was recorded with a Sony TR45E video camera. This camera has a macro function which allows focusing at 10mm from the lens, and this was the distance of the fixed reference template (the cross) from the lens. The bottom face of the bob (the circles) was at 11mm from the lens, and 1mm from the fixed template. As per the user's manual, when this camera is set to macro the autofocus function is automatically excluded.
