Apollo NEA 2008 TC3 collided with Earth in a deserted region of Sudan on 2008 Oct. 7 UT. Based on our observations and assuming G = 0.2, we found an absolute magnitude H = 30.79 ± 0.08. With our H value and pV = 0.09, we estimate the diameter of 2008 TC3 to be D = 3 ± 1 m. Our period analysis of the lightcurve, which assumed a single period, found periods 97.05 s or 194.34 s. These do not account for the tumbling nature confirmed by Pravec and Harris using other data and so probably do not indicate the true rotation characteristics of the object.
