From
Alexander van der Horst at NASA/MSFC <Alexander.J.VanDerHorst@nasa.gov>
A.J. van der Horst (NASA/MSFC/ORAU), A.P. Kamble, R.A.M.J. Wijers,
E. Rol (U of Amsterdam), C. Kouveliotou (NASA/MSFC) and K. Wiersema
(U of Leicester) report on behalf of a large collaboration:

"We observed the position of the GRB 100418A afterglow with the
Westerbork Synthesis Radio Telescope at 4.8 GHz at April 20 20.74 UT
to April 21 8.71 UT, i.e. 1.98 - 2.48 days after the burst (GCN 10612).
We detect a radio source with a flux density of 369 +/- 29 microJy
at the position of the optical counterpart (GCN 10616).

We would like to thank the WSRT staff for rapidly scheduling
and obtaining these observations."
