Hallinan (Caltech) on behalf of the OVRO-LWA collaboration.\n\nWe report contemporaneous observations of the localization region of the BNS gravitational wave event S190425z (GCN 24168) with the OVRO-LWA. The observations span from -1 hour to +3 hour relative to the merger time (2019-04-25 08:18:05.17 UT), with continuous coverage of approximately 57% of the probability region. This includes the locations of the 2 candidates identified in ZTF (GCN 24191). The OVRO-LWA is a low-frequency radio telescope operating from 28 MHz to 86 MHz, with an approximately 20,000 sq. deg. instantaneous field-of-view.\n\nData reduction and analysis have commenced investigating the possible presence of a low frequency prompt counterpart to the event (see Anderson et al. 2018, Callister et al. 2019).",
