Transit of venus - 8.6.2004 at 12.02 Tampere Observation number 50147

Visibility IV / V

Tapio Lahtinen, Tampereen Ursa

Treasures of the archives from 2004.

From time to time, fast-moving cloudboards obscured many frames from my first ‘live’ webcam broadcast.

I visually viewed the first and second contacts with a 500mm f / 8-telephoto + 40mm eyepiece combination. I did not notice the phenomenon of a black drop at that time.

The third and fourth contacts could not otherwise be detected due to the clouds except from other foreign webcam broadcasts.
