Technically, the morning sun and evening sun are the same sun, but they may differ slightly in brightness and color. The morning sun is typically softer and more diffuse due to the earth's atmosphere and the angle at which sunlight hits the ground. On the other hand, the evening sun may appear brighter and more intense because it is lower in the sky and has to pass through more of the atmosphere. In general, the sun is brightest when it is higher in the sky, which is usually around noon.
