The NGC 6946, also known as the Fireworks Galaxy at 6Mpc, is the most prolific galaxy for SNe. The SN2017eaw, the 10th SNe occurred in this galaxy is a Type IIp Supernovae. We analyzed optical photometric and spectroscopic measurements of SN 2017eaw from 1 to 302d after the explosion. The light curves and spectra suggest that SN2017eaw is a typical type IIP event, with a plateau phase duration of ~80 days and a maximum absolute magnitude of Mv ~ -17. In this poster, we will present our analysis result and an optimal model for the progenitor of SN 2017eaw.
