A secular period variation was established through the O-C of all the available times of maximum light and those newly acquired through CCD photometry. In the present study we have demonstrated that BO Lyn is pulsating with one stable varying period whose O-C residuals show a sinusoidal pattern compatible with a light-travel time e&#64256;ect.]]></p></abstract>

La variación secular se estableció mediante el análisis de los tiempos de máximo con el método de O-C recabados de la literatura y con los nuevos adquiridos con fotometría CCD.
