I was staring at the full moon and saw something travel out of the mouth crater and went south southwest. if you were to put a compass on the moon's circumference it came out exactly south and traveled south for half the distance and changed course south southwest to the darkside. it was a black circle. i think the sunlight was reflecting off of it causing it to sort of pulsate. i thought maybe something in my eye but it didn't extend out into space. it was as if it went over the horizon. at first it was kinda tiny and grew in size when it came out of the crater. if it was something it was would have to be many miles wide to be seen. it was real quick. i just want to know if anything was seen 1/10/2020 8:15ish pm eastern time on the surface of the moon traveling south southwest. the moon's facial expression looks horrified .
