Hi, interesting discussion on planet Venus, here is some more on the
'ashen light phenomena' from wiki and a link to a page about a recent attempt to view it from India...
Amateur astronomers attempting to view the Ashen Light can try it by using an occulting bar, an opaque mask for one’s eyes. This lens blocks the sunlit portion of Venus which greatly cuts down extraneous light that is scattered in the eye, improving the chances of witnessing the faint Ashen glow. However, Venus light scattered by the Earth's atmosphere and in the telescope's lens still works against the observer, and it is very hard to get the timing just right. Nevertheless, there have been calculated times in which the light scattered by Earth is covered partially by our Moon. For example, on July 17, 2001, the progression of a crescent Moon temporarily hid the illuminated portion of Venus. Unfortunately the location needed to catch this almost perfect occultation was somewhere in the middle of the Atlantic Ocean, and it was only visible in this manner for 10 to 20 seconds.
