Unusual objects emerged, reminiscent of a light being turned on, only to gradually fade away. It’s akin to dimming lights one by one in a sequence, all within a span of just 10 to 15 seconds. What could this be?

It sounds like you might be describing a phenomenon often referred to as “light artifacts” or “light anomalies.” In space, there are various possibilities for such observations, including:
Satellite Reflections: Satellites can reflect sunlight, creating bright flashes as they pass overhead. This could appear as lights turning on and off in a sequence.
Distant Stars or Planets: Sometimes, natural celestial objects can appear to brighten and dim due to atmospheric conditions or their own movements.
Geostationary Satellites: These satellites are positioned over a fixed point on Earth and can appear to blink as they move into or out of the sunlight.
Space Debris: Small objects orbiting Earth, including spent rocket stages or other debris, can reflect sunlight as they tumble.
Optical Illusions or Atmospheric Effects: Sometimes, the atmosphere can create illusions or distortions that cause objects to seem like they are fading in and out.
If you have more information about the location, timing, or specific characteristics of the lights, that might help narrow it down further!
