A stack of colored lights that were flashing

The object is still visible at the same height from the horizon but the flashing or movement seems to have lessened. Red and green colors are still visible with bare eyes. The object seems to have not moved for the past 30 minutes at least now. It now looks like a larger yellow light below with green and red flashes with a smaller flashing light above. We have regular fly overs of medical helicopters so my initial thought was that, but when it didn’t move I realized it was something else. At 10:27, it is possibly twice as high from the horizon as when we first saw it and is getting dimmer. When looking through binoculars, the object seemed to be wildly spinning or rotating, and my husband thought it seemed to change shape and spiral around. My husband is a retired scientist and I am a retired teacher. This is our first report we have filed but not the first unexplained object in the sky we have seen during our adult lives.
