1 Otero, Sebastian Alberto Large range for a GCAS. V-range given. Photographic maximum magnitudes in the past are much brighter (8.8 pg). ASAS-3 shows it at a faint state during the last decade around V= 10.4-10.5.
2 GCVS Team During the faint phase in 1951 the shell spectrum was observed [J.Sahade, ApJ 115, 578, 1952.]. Type E with a very long period is possible [D.J.K.O'Connell, MN 111, 111, 1951.].
