Hi Jay, Thanks for the heads up. Checking the Minor Planet Center at http://www.minorplanetcenter.org/iau/MPEph/MPEph.html it shows Utahans may have a pretty good chance of spotting this one. It shows that at 0100 tomorrow it will be 40 degrees above the horizon and possibly as bright as mag 11.8. But look quick as it'll be streaking along at an incredible 12438.91"/min meaning that less than 20 minutes later it will be mag 16 and have already dropped below the horizon. patrick On 28 May 2012, at 21:23 , Jay Eads wrote:

reports that 2012 KT42, about the size of a mini-van or small bus will pass by planet Earth on May 29th at 07:00 UTC (03:00 Eastern US time). It will pass at around 14500 kilometers or 8900 miles, just slightly larger than the diameter of the Earth. This Italian Blog has an animation of the objects and some good info on it:
