The low humidity high pressure atmosphere that was overhead made this observation possible. Venus was about 13° North and 3° to the East of the sun and I knew I could safely block the sun from reaching my eyepiece using a large pine tree to block out the solar disk. Venus at the time of the observation was about -4th magnitude and 2.5 % illuminated. The disk of the planet was about 59” of arc in diameter and only 0.29 AU (27 million miles) from earth. Sketching: 4.25"f/6 Newtonian 6mm eyepiece 107x For this sketch I used: blue construction paper, 11"x 9", a white Conte' pastel crayon and a blending stump, for templating the planet as a circle I used a lens cap. Brightness and contrast were slightly increased (+2) after scanning.

Thanks for reminding us as I have forgotten that its phase has changed that much recently. You've alerted us that its time to observed it before it falls in front of the sun soon.

This day time window to capture Venus was brief. After this weekend I am hopeful conditions for observing will return.

I have wanted to repeat the observation but the sky is not cooperating yet. Frank Post Extras:       Tom Machtemes super member Reged: 06/09/08 Loc: Evergreen Park, Ill.

You don't need much aperture or magnification on Venus during the day but very clear skies are a must. I got the blue paper for daytime moon sketching. I am still waiting for my opportunity.
