We report the discovery of DLT17cd/AT 2017fzw. The object was discovered on 2017 08 09.36 UT at R~17.17 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 09.80 UT using a 1m LCO telescope (LCO node at the Siding Spring Observatory).
No observations of the host galaxy, NGC 2217, were possible in the period between the discovery and 2017 02 20.22 UT since it fell outside the visibility window of the field.
DLT17cd/AT 2017fzw is located at RA: 06:21:34.77 Dec: -27:12:53.51, (+67.09, -68.49 arcsec offset from the center of NGC 2217). The discovery image was taken in a 'Clear' filter which was calibrated to an approximate R-band magnitude using the USNO-B1 catalog. Further observations are encouraged.
