Special Edit: We have apparent winners in all three categories. Kudos to Christopher Faris (telescope & binoculars) and Dave Mitsky (naked-eye). Heartiest congratulations to both of these fine stargazers! See posts below.
Cheer Up! There is no need to bemoan the fact that Venus has left the evening sky and the transit is over. It will soon be reincarnated as the brilliant Morning Star. As such, it will remain in the pre-dawn eastern sky for more than half a year.
I propose 3 contests for 3 categories of observations:
1) Naked-Eye (Grand Prize)
2) Binoculars
3) Telescope
Below are listed Venus' elongation from the Sun and fraction illuminated as it will be seen around Sunrise in Chicago (05:15 CDT - 10:15 UT) for the remainder of June.

I have created a graphic of the eastern sky as seen from Chicago about 20 minutes before Sunrise. Click the link below:

Please report your observations in this thread. Include details such as time (with zone noted) and location. Even reports of negative results will be appreciated. No prizes - just bragging rights.
