We report the discovery of DLT17cg/AT 2017gaw. The object was discovered on 2017-08-14.28 UT at R~18.28 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 on 2017-08-14.66 UT using a 0.4m LCO telescope (LCO node at the Siding Spring Observatory).
DLT17cg/AT 2017gaw is located at RA: 01:15:35.23 Dec: -00:50:40.3, (3.45W, 11.70S arcsec offset from the center of the host galaxy, UGC 807). We do not detect the transient (R>19.4 mag) on 2017-08-09.19 UT or in prior imaging of the field. The discovery image was taken in a 'Clear' filter and calibrated to an approximate R-band magnitude using the USNO-B1 catalog. Further observations are encouraged.
