  We analyzed 64 radio observations at the frequency of 8.4 GHz of the
Wolf-Rayet star WR 112, taken from the Very Large Array archive. These
observations cover a time baseline of 13 years, from June 2000 to July 2013.
The radio structure of WR 112 is consistent with it being a point source in all
the epochs and with its flux density varying from 0.6 mJy to 2.1 mJy. We tried
to search for periodicities in these variations but our results were not
conclusive. We also looked for extended emission from the infrared nebula that
surrounds WR 112, settimg upper limits of 50 $\mu$Jy. Finally, we used the
highest angular resolution images to measure the proper motions of WR 112,
obtaining $\mu_\alpha\cos \delta = -2.6 \pm 1.1 \mbox{ mas yr$^{-1}$}$, and
$\mu_\delta = -5.4 \pm 1.4 \mbox{ mas yr$^{-1}$}$. These proper motions are
smaller than those previously reported, but still suggest significant peculiar
motions for WR 112.
