The most recently recorded outburst was detected by J. Pietz on 
1996 Dec 7.88 UT at mv= 14.3 (cf. vsnet-obs 4521, vsnet-alert 624). 
I would suppose that several (normal) outbursts were missed in the
last three years. The mean cycle length appears to be about one year,
but may be as short as five months.

P.S.:
I think Mike Simonsen's observations were actually made 0.5 days
later than stated.
The current outburst is very likely a supermaximum, so time-resolved
photometry is strongly recommended.
