NavList:

If you know just where to look, Venus can be visible to the naked eye in
full daylight. I have only tried finding it the once but, that time, I
did find it. Needed some concentration to keep it in sight though, since
you have to look in exactly the right place or it disappears.

 

 

My father-in-law was a navigator during W.W.II.  He told me that his captain, who acted as a backup navigator, could usually find Venus and get a sight on it.  He was a great story teller and sometimes embellished to make the story even better.  I always put the Venus daytime sights in the "embellished" catagory.  I guess I'll have to eat crow!
