Actual observable horizon for satellites on an orbit line map?
It is not that satellite. As it passes over Finland, it has an altitude of 27000km and a magnitude of about 12. You won't see it. All Molniya orbits are similar.

The website Satflare to shows the region in which satellites are visible (it uses a blue ring around the satellite) Your satellite was so high that it was visible from nearly the whole hemisphere.

I won't try to identify your object, except to say that an object as described is not in orbit.
