Two drawings I made of Venus this morning in good seeing conditions.  A streak extending from the terminator out into the south was visible along with a vaguer streak to the north.  Some bright spots were spotted on the limb.

Paul,

Nice sketches as always. I was observing at about the same time as yourself although under less transparent skies. I'm pleased to find that my sketch reasonably matches yours which gives me comfort I might be doing it right!

I too saw the southern and northern streaks although I angled the southern one somewhat differently and made the northern one a bit larger than yourself. Also picked up the dark bands around both cusps. The main differences are that I saw more terminator shading but not the bright limb spots.

Given the difference in aperture, transparency and the vague nature of Venus' marking I consider the agreement quite good. It does, I believe, show there is still value in an observer using eyeball, pencil and paper even in the this age of imaging.
