We report the discovery of DLT17bk/AT 2017ejb. The object was discovered on 2017 05 28.2 UT at R~ 17.21 mag, during the ongoing D<40 Mpc (DLT40) one day cadence supernova search, using data from the PROMPT 5 0.41m telescope located at CTIO. A confirmation image was obtained with the 0.4m LCO telescope at Haleakala on 2017-05-28.3 UT. DLT17bk/AT 2017ejb is located at RA: 12:48:36.01 Dec: -41:19:33.5, (+148.60'' E +54.50'' N offset from the center of the host galaxy, NGC 4696). We do not detect the transient (R>20.57 mag) on May 2017 22.2 UT or in prior imaging of the field. All images were taken in a 'Clear' filter which was calibrated to an approximate R-band magnitude using the USNO-B1 catalog.
Further observations are encouraged.
