What characterizes libration fading of an EME signal?
Pick an answer to check it.
Answer: B. A fluttery, irregular fading
Libration fading is a fluttery, irregular fading caused by the moon's slight wobble, which makes reflections from different parts of its rough surface add and cancel. It is not a slow pitch change.
Tip: Moon wobble = fluttery fading.
