1 Linnolt, Mike AAVSO observer LMK reported it to be unusually bright (V=11.8) Dec 30, 2007. It shows relatively large variation. For example, ASAS-3 recorded V=12.23 on June 29, 2004 and also recorded five outbursts in 2002 (amplitudes typically 1 mag or slightly less with intervals of 1.5-3 months). Historically, Koshiro probably recorded this type of variation in Nov 1988 (reaching mag 12.2). Such behavior has not been documented (as far as known) and needs further study.
2 GCVS Team Porb = 0.1662d? [J.B.Hutchings, A.P.Cowley, PASP 96, 559, 1984.]. High and low states of the system are observed.
