We report the discovery of DLT17aw/AT2017drh. The object was discovered on 2017-05-03.36 UT at R~17.9 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 PROMPT image taken on 2017-05-01.36 UT shows a clear, but low signal to noise, detection of the transient, with R~20. We do not detect the transient (R>20.5) on 2017-04-29.36 UT. All images were taken in a 'Clear' filter which was calibrated to an approximate R-band magnitude using the USNO-B1 catalog. SWIFT follow-up observations have been triggered and further observations are encouraged.
