Deutschland
 Java
Applet
In Deutschland ist
nur die Endphase des
Transits zu beobachten. Beginn und Mitte liegen vor Sonnenaufgang.
Die maximale Dauer des Transits in
Deutschland (2h 25m) ist im
Nord-Osten zu sehen, z.
B Berlin oder Stralsund, im Süd-Westen, z. B. Stuttgart, sind
es nur nur 1h 38m.

Die berechneten Zeiten sind wegen
begrenzter Rechengenauigkeit des Applets auf 1-2 Minuten genau. Es
wird nicht zwischen innerem und äusserem Kontakt unterschieden
(Zeitintervall 18 Minuten):
"Ingress" und "Egress" sind für den Venus-Mittelpunkt berechnet.
Die Position der Venus auf der Sonnenscheibe hat einen Fehler von
höchstens
0,4 Venusdurchmessern (25 '').

Venus bewegt sich dort
ungleichförmig und unstetig über die Sonnenscheibe:
Sicherheitshinweis:
Sonnenbeobachtungen erfordern größte Vorsicht und Sachkunde,
da sonst bleibende Augenschäden drohen. Eine
Sonnenfinsternisbrille bietet Schutz, auch die Projektion des
Sonnenbildes ist ungefährlich. Benutzt man ein Fernglas oder
Teleskop, muss ein geeignetes Sonnenfilter, das 99,999 % des
Sonnenlichts absorbiert, auf der zur Sonne weisenden Seite angebracht
werden.

At greatest transit (01:30 UT) the image point of the Sun and of Venus
(subsolar point) is located at 22.7° N
(=declination of the Sun and Venus) and 157.2° E (=360° -
Greenwich hour angle of the Sun and Venus) in the Pacific Ocean: there
the greatest transit happens in the zenith of the observer:

Venus is moving across the Sun's disk
like this:
Earth, Mercury, Venus und Mars on 2012 June 6
by my Planet Applet
The
geocentric end of the transit is at 4:49 UT. The borderline separating
the sunlit and darkened hemispheres runs from central Africa to Spain,
to east of Ireland, and Greenland, which is in agreement with the
prediction Proctor's book plate IX, published in 1882.
