A. Corsi (TTU) and N. Palliyaguru (TTU) report on behalf of a larger
collaboration:
We imaged again the position of the Pan-STARRS transient PS15dpn (Chambers
et al. GCN 18811;
also iPTF15fgl, Cenko et al. 18848), located in the error region of
LIGO/Virgo G211117 (LVC
et al., GCN 18728), with the Karl G. Jansky Very Large Array (VLA) in its
DnC configuration.
A provisional reduction of the images collected since the start of our
follow-up (Palliyaguru
et al. GCN 18846) shows a ~6 sigma excess at 6 GHz at a location consistent
with PS15dpn. Our
observations show no evidence for variability of this radio counterpart
between 08 Jan 2016
and 14 Jan 2016 (UTC). We report below a summary of our observations and
provisional results.
Further observations are planned.
