Thanks for this interesting link. Unfortunately it did not answer my question. I did find the asteroid schedule quite interesting. I see that a small 22 ft. diameter asteroid passed by at .2 Lunar Distance on July 7th. Also a very large one is due soon. It is a scary almost 1/2 mile in diameter, but fortunately 17 Lunar distances from Earth.
Auroras were the only result of this “crack”. :^)
