Bright light staying in same area of the sky; higher than airplanes moving in quick sporadic formations.

Looking southwest into the sky a light about as bright as a satellite moves steadily back and forth through a small area sometimes changing directions with small bursts of speed. This was first noticed this morning at 05:45 with the light being brighter than any stars or satellites and much higher than any airplane. We noticed again tonight around 19:15 that it was in the same area and watched for 10 minutes as it made the same back and forth movements, sometimes small circles and other quick sporadic direction changes that planes and satellites don’t make. Our first thought was a drone but it looks too high up. We would look forward to any answers or debunks.
