Not a very close encounter of Toutatis with Earth on Sept. 29 (some 1.5 lunar distances) but fun to see an asteroid move so fast on the sky. Sept. 22 when this sequence was taken, was about the last day for us Northerners to see Toutatis, as it was rapidly racing South and the moon was growing and approaching it.
