We propose to take deep H alpha and V band images of this field. Discovery of any excessively bright object in H alpha could pinpoint the optical counterpart of the burst. The search for counterparts from the existing catalogues (see Skyview on the net) has turned empty but our exposure could reach deeper. Here we assume the counterpart is close toour galaxy so that no considerable Hubble shift is present.
