When is a star's twinkling effect generally most pronounced due to atmospheric path length?
Answer
When the star is low on the horizon.
Light from an object low in the sky travels through a much thicker column of the Earth's atmosphere, providing more opportunities for refraction and distortion, thus leading to more pronounced scintillation.
