Sure it might be hard to see a hologram that is in space, but still .

So if I can see this and others else where on the earth can, then it seems the two craft are staying near each other.
I have seen the ISS, shuttle and Hubble. Based on the time I go outside and watch. The objects pass over. I am in the country where it is dark so if it is not cloudy I will see them. I'll verify the ISS and STS again tomorrow at the listed times.
If so why is the shuttle so far away from the ISS?

Maybe because I am unsure of the procedure but doesnt common sense tell you that if Nasa waits on this golden window that this would be the best time for the shuttle to meet the ISS as two vectors coming to an almost point at the proper orbital distance?
This of course would save time and money. If so why is the shuttle so far away from the ISS?
Why does it take a day or two after launch for the Shuttle-Mir rendezvous to take place?
Once the Space Shuttle launches into the same orbital plane as Mir it still has the complicated task of getting to the same spot in space at the same time as Mir. What we do is launch into an orbit in the same plane as Mir but with a lower altitude above the Earth. This means that the Shuttle circles the Earth faster and thus catches up with Mir. This is done with a carefully planned series of maneuvers, slowly closing in on Mir's angular position around the Earth while slowly closing in on Mir's altitude as well. The slowness is important. It helps ensure the safety of the two vehicles as they approach each other, while it gives people and navigation systems time to evaluate progress and devise the exact next move, every step of the way.

I would guess that they want to get supplies unloaded and whatever business has to be done and undocked before sunset over the U.S. where there might be more prying eyes than there would be from the rest of the world.
I suspect there might be more than one Secret Space Station and that it will be docked with tomorrow, during U.S. daylight hours.
Any confirmation or debunking of this theory would be greatly appreciated.

Space is supposed to be at absolute zero. Anything directly in the sunshine heats up incredibly. Skylab overheated when one of its solar panels failed to deploy properly, yet Apollo 13, in direct sunlight and in a lethal radiation zone, supposedly got cold!
On the launch pad the ship is air conditioned from ground services. In space the ship is air-conditioned (powered by fuel cells), if you turn off that air conditioner the ship gets cold! At least that is what NASA’s line of logic dictates.
Apollo 17’s LEM sat on the Moon in the direct sun for 75 hours straight. Without massive power and refrigeration units the only way to cool the LEM would have been with the explosive cooling of water. Many tons would have been necessary for that time period. The astronauts reported that the LEMs were “too cold to sleep in”. How cold would your closed car be after 75 hours of direct sunlight
