A significant fraction of asteroids between the orbits of Mars and Jupiter are known to be fragments of larger parent objects. Asteroids that share certain orbital characteristics and chemical composition are classified as members of collisional families. Because of their shared origins (nature), surveying objects of the same family is an effective strategy in studying the YORP effect, whereby solar radiation alters asteroid spins (nurture). Thus, to increase the sample size of Koronis family objects of known rotation periods, we observed Koronis family asteroid (1442) Corvina. Conducting observations near Corvina's stationary point, when it appears nearly unmoving in the sky, enabled the use of the same reference star over the course of 19 days. By tracking the cyclical changes in Corvina's magnitude (brightness) relative to this background star, we produced a composite light curve and confirmed Corvina's rotational period.
