7 objects best described as small suns, round orange objects that appeared and disappeared in succession in and out from same locations

Was observing the western horizon shortly after sunset on a clear night, western horizon was still illuminated from previous sunset, but sun had completely set. An object as described above appeared and traveled easterly for approximately 6 seconds at which time it simply disappeared. Emidietly thereafter another object identical to the first one materialized in what seemed to be the exact entry point of the previous one, and continued on the same course blinking out also at the same position in the sky as the previous one. This exact pattern continued for 4 more objects, with the 7th and final object materializing slightly to the left and at lower elevation then the previous 6. At no time was there more than one visible in the sky at the same time. My first thoughts were potentially satellites reflecting the setting sunlight while passing through this light in their orbit trajectory. However, the size and diameter of the objects was much larger than a typical satellite, as well as the lower elevation of the objects. Using an aircraft as a comparison of elevation for the objects, I would guess approximately 35,000 feet, or cruising altitude of a jetliner.
