We report the discovery of DLT17u/AT 2017cbv. The object was discovered on 2017-03-10.14 UT at R~16.05 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 same instrument on 2017-03-10.16 UT, where the transient was detected at R~15.96 mag. DLT17u/AT 2017cbv is located at RA: 14:32:34.42, Dec: -44:08:02.8, (-67.59'', +145.26'' offset from the center of the host galaxy, NGC 5643). We do not detect the transient (R>20.0 mag) on 2017-02-16.25 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.
