We present observations that define 14 secondary sequences on the photoelectric JF system of Couch and Newell (1980). In addition to their main role of providing calibration sequences for photometry in 14 distant clusters of galaxies, these observations extend the JF system to fainter magnitudes and make it accessible to Northern Hemisphere observers.
