Is it at all possible to see starts during daylight hours? The reason
I ask is last week, I was in the Adirondack Mts. in New York, at the
annual hot air balloon festival. It was about 5:30 PM and I was lying
on my back, idly gazing ito the sky waiting for the balloons to start
launching. It was a very clear day. I had shielded my eyes from the
sun, which was on it's way down, but was still high enough in the sky
to seem like full daylight, as I watched a wayward kids balloon
sailing away. I suddenly noticed what appeared to be a star almost
directly overhead. I watched it for sometime, waiting to see if it

At times you can see planets in the daytime if you know right where to look
(Venus, in particular), and it would look like a star, but it or Jupiter
wouldn't have been directly overhead at the time...

But the stars Vega and Arcturus would have been approximately overhead at
that time (5:30PM EST) so one of those may have been what you saw. Those
are the brightest stars that would have been closest to directly overhead at
that time. or, slightly less likely, Altair.
