We have observed a 20 x 20 deg field-of-view centered on the  LIGO/Virgo G298048 localization region  (LVC GCN #21513) with the Murchison Widefield Array.  Observations occurred on 2017-08-18, 2017-08-19, 2017-08-20, 2017-08-21, and 2017-08-22, all from roughly 07:00 UT to 09:30 UT, at a central frequency of 185 MHz.  Note that the array is in the process of being reconfigured, so only 5/16 of the tiles are operational.  Analysis of this data is underway, and subsequent epochs are planned.

We thank the MWA Operations team for supporting these observations.
