文摘

Photometric observations of a new eclipsing binary system have been obtained. The system was found to be as A-subtype of WUMa with fill-out factor of about 69%. We estimated the orbital and absolute parameters of the new discovered system. The evolution status was performed along with ZAMS and TAMS tracks.
