Should have read :- Comparison of E (1950.9418) and F (1990.8186) plates (the only similar passband plates available at more than one epoch) sourced via the USNO NOFS image archive server at http://ftp.nofs.navy.mil/data/FchPix/ helps to confirm the variability of this object. J and E plates are "blue" and "red", E and F plates are "red" and "red". Apologies John John Greaves UK
