As more observations are made the close approach distance is refined. It has remained within the margin of error since the first few observations.
FYI, MOID is not the close approach distance.
Closest approach is now calculated to be 58,996 miles with a maximum of 59,029 and a minimum of 58,962. That's a pretty narrow margin of error.

Duck! Asteroid 2012 TC4 to fly by Earth tonight
An asteroid the size of my front yard will zoom by 59,650 miles from, well, my front yard tonight. At average walking speed, you could step from one end of this boulder to the other in just 13 seconds.
No one’s in danger from this midget asteroid because it’s much too far away to trouble the lumbering Earth. If anything, our planet’s gravity will likely bend and alter 2012 TC4′s path during closest approach. That happens at 12:31 a.m. (CDT) tomorrow morning Oct. 12

why do we just find out about these things at the last second? what if this would have been on a clear path toward earth and we just found out. wtf is our goverment really doing? this is bs
Discovered by Pan-STARRS observatory in Hawaii on October 4th, 2012, Asteroid 2012 TC4 will make its close approach to Earth this week.

On March 18, 2004, LINEAR announced a 30-meter asteroid, 2004 FH, which would pass the Earth that day at only 42,600 km (26,500 mi), about one-tenth the distance to the Moon, and the closest miss ever noticed. They estimated that similar-sized asteroids come as close about every two years.
On August 10, 1972 a meteor that became known as The Great Daylight 1972 Fireball was witnessed by many people moving north over the Rocky Mountains from the U.S. Southwest to Canada. It was an Earth-grazing meteoroid that passed within 57 kilometers (about 34 miles) of the Earth's surface. It was filmed by a tourist at the Grand Teton National Park in Wyoming with an 8-millimeter color movie camera.
