The orbit of Saturn and Jupiter are getting much lower in the night sky coming up to the conjunction of the two planets. Does this possibly mean they at some point not be visible here in the States for a period of time after the conjunction?

I hope this will not be true but I did want to ask hoping some one here will know the answer to this question of mine.

Thank you

Yes. They are setting earlier and earlier in the day and soon they will only be above the horizon during the day. They are there, but too dim to see in daylight. Then around March/April, you'll start seeing them in the morning sky. They'll rise a little earlier each morning until you'll see them all night. They'll also be moving further apart over that time.

Interestingly I covered a similar issue with far more experienced photographer who mentioned that daylight planetary photography IS possible, an infra red filter is your best bet but I believe there are a few ways of still being able to get a pic with the sun up. I'm not sure if the planets will be high enough during the day but it may help.

They are setting earlier, and will be on the other side of the sun from us.

You can get Venus on a clear day, I tend to try during lunar conjunctions so I can guide off the moon.

Do you know how to find out how long will they will not be visible to us? Months? Years?? I am hoping only a few months........

Months at most. You'll see them any time the earth is between the sun and the outer planets so that when it is night on the hemisphere of the earth that is facing away from the sun, the planets are on that side of the earth. Since the earth takes only 1year to go around the sun while the gas giants take much longer, you're guaranteed to have sometime every year when the outer planets are visible.

I was aware of Venus, though I've never looked... but I was surprised to find that it may be possible for less bright planets to be done. Not having an IR filter nor clear weather I can't try it out myself!

It is just needing to know WHEN to look WHEN we also have clear skies. Two items they vary a lot!

Agreed. Planetary movements are totally predictable. I think Sky and Telescope had a web page where you can pick any date in the future and see what the sky looks like at your location. As far as the weather is concerned, you're on your own. ;-)a

Here is the website that shows you the sky at some arbitrary day in the future.

Let me (over)simplify it to you.
It takes 12 months for us to circle the sun, so worst case to see anything that is on the other side of the sun would be 6 months. In practice, it is less because we don't need to completely be "broadside" to the sun to see around it- it is like seeing a deer on the far side of a tree, slightly to one side. Just a few steps still has the deer on the far side of the tree, but on the other side. I over simplify because, as soon as I take the few steps, the deer usually run away ;-)a . I'm also ignoring the planets are also moving in their own orbits. That's why @SteveInNZ said March/April - roughly 4 months out.
