A period update for the five eclipsing binary stars - SS Ari, TY Boo, DF Hya, Z Lep, and TY UMa.

SAMOLYK G.

Abstract (from CDS):

AAVSO observations of 5 eclipsing binary stars indicate a large discrepancy when compared with the elements from the 4th edition of the General Catalogue of Variable Stars (Kholopov et al. 1985). New periods for SS Ari, TY Boo, DF Hya, Z Lep, and TY UMa have been calculated.
