Photometric parameters of the system and its components are derived using the Wilson and Devinney code based on the data taken from the SuperWASP public data archive. Photometric solutions indicate that SY Hai is a marginal contact binary system with a mass ratio of q = 1.59 and a contact degree of f = 6%.eninfo:eu-repo/semantics/closedAccessConference Object181510.1063/1.4976458N/AWOS:0004352051001142-s2.0-85016071213Q4
