Watching and waiting!!!
First of all stars have no apparent size either naked eye or in a telescope. They are point sources of light. They differ only in apparent brightness and color. A brighter star is not necessarily "bigger" than a dimmer star, it may just be closer to us. However, optical physics dictates that all point sources of light have the same size called an "Airy disc"(Google it). Even the closest star is 4.3 light years away which is about =24 trillion miles.It's an unimaginably huge distance, there is just no way to see the star as anything other than a point of light.
Secondly, when bright stars get that close to the horizon they will twinkle with all the colors of the rainbow depending on the atmospheric conditions.
It's not the space station since it obviously moves much more rapidly than the Earth rotates.
Planets generally don't twinkle, but they can given a very turbulent atmosphere. Possibly what you saw was a geosynchronous satellite but I doubt it since they are in very high orbits very far away and very very dim.
Maybe a distant plane flying directly toward you, a planet(Jupiter,Venus,Saturn) a bright star.
Since I don't believe in UFO's, that's not a possibility. However, I do believe that satin uses what many people think are UFO's as just deception for demonic activity. Don't fall for the UFO thing, it's a lie!
I've been looking at the night sky for 40 years and have never seen a UFO. I would say a star or planet close to the horizon.
IN CHRIST JESUS,
22 But the fruit of the Spirit is love, joy, peace, patience, kindness, goodness, faithfulness,
23 gentleness, self-control; against such things there is no law.
