For the first time, astronomers have found an object on a certain collision course with Earth. Fortunately, it is so small it is not expected to cause any damage, burning up in the atmosphere somewhere above northern Sudan in the wee hours of Tuesday morning. It may, however, produce a brilliant 'shooting star'.

The impact location has been narrowed down to 21N, 33E, at 2:46 UT, which is in in northern Sudan. The probability for impact is between 99.8% and 100%.
The asteroid will track from the northwest, so observers in Europe, northern Africa could possibly see the atmospheric entry phase.
Depending on the composition the atmospheric impact and breakup should release ~ 1 kiloton of energy.

The absolute magnitude indicates that the
object will not survive passage through the atmosphere.
