Type II-P Supernovae Usually Remain Bright for About 100 Days. But iPTF14hls Remained Bright for Mor

iPTF14hls grew bright and dim again at least five times over two years. This behavior has never been seen in previous supernovae, which typically remain bright for approximately 100 days and then fade.
