We report the detection of a potential cosmic radio transient source using the two stations of the Long Wavelength Array. The transient was detected on 2017 October 18 08:47 UTC near the celestial equator while reducing 10,240 hr of archival all-sky images from the LWA1 and LWA-SV stations. The detected transient at 34 MHz has a duration of 15-20 s and a flux density of 842 ± 116 Jy at LWA1 and 830 ± 92 Jy at LWA-SV. The transient source has not repeated, and its nature is not well understood. The Pan-STARRS optical telescope has detected a supernova that occurred on the edge of the position error circle of the transient on the same day.
