Andrew Howell, Curtis McCully, Stefano ValentiGlobal SN ProjectSN Ia0.029Global SN ProjectWe obtained a FLOYDS spectrum of AT 2018dhw at 2018 July 19.51 UT. Using SNID (Blondin & Tonry 2007, ApJ, 666, 1024), we find several good fits to normal Type Ia SNe around maximum light. The measured value of the redshift (0.029) is obtained from the SNID fit.
