The Mount Lemon telescope first observed a small space rock early on Monday... the noticed item is actually an asteroid measuring several feet in diameter and the traveler was expected to enter the Earth's atmosphere over northern Sudan just before dawn tomorrow at 5:45 a.m. local time (10:46 p.m. EDT Monday). Should be quite a fireworks show! The odds of any sizable fragments surviving the passage through our atmosphere is rather small. The small space rock, designated 2008 TC3, will be traveling on an eastward trajectory that will carry it toward the Red Sea. The Mount Lemon telescope, of the NASA-funded Catalina Sky Survey, tracks asteroids and comets that pass close to Earth. The Near Earth Object Observation Program, commonly called "Spaceguard," plots the orbit of these objects to determine if any could be potentially hazardous to our planet.
