2010 AB78 was the first NEO discovered by WISE in early January. It came back through the WISE scan path in February and again in July, appearing in a total of 89 frames. The lines-of-sight to the asteroid cover 180 deg in RA and 70 deg in Dec. These data are used to constrain the rotation rate, rotation axis, thermal inertia
and size of 2010 AB78 using the rotating cratered thermophysical model of Wright (2007). All data were obtained on the same side of the WISE scan circle, limiting our ability to constrain the thermal inertia. The effect of poorly constrained parameters on the size is handled using a Monte Carlo Markov Chain approach.
