Odd Behavior of WW Cet

After a great many years of apparently exhibiting only normal UG-like behavior (consult a LCG 5k day plot), over the past couple of observing seasons 0006-12 WW Cet, classified currently as a UGZ-type star, has shown almost continuous highly peculiar activity. The star's apparent range has dramatically contracted and it has been experiencing a series of rather dissimilar standstill-like events.

I would call attention to the fact that since mid September the star, after having fallen to an apparent minimum state in August, WW entered a new standstill-like phase with the magnitude fluctuating in the mid 13's.

My observations are showing the same result. I observed WW Cet very early in this observing season which was around the 14.0 mag range, then faded to the 15's for a while and now back up the the 13.0 mag. range and holding. WW Cet has not had a decent outburst since it's first recorded standstill.

Hello everyone,

There haven't been any followups to John's post since 2012, but WW Cet has continued to behave strangely since then -- in fact, it never really returned to its normal behavior since the standstill of 2010 (see Simonsen & Stubbings 2011).  WW Cet is still doing strange things today, and I'd recommend plotting the long-term light curve for yourself.  Plotting from the year 2000 onwards shows how striking the change is since 2010.  It's as if WW Cet is a totally different star.

This star is a good target for early-morning observers.  It's just coming out from behind the Sun, so if you're up before sunrise and are looking for good telescopic targets (fainter than 12th), please consider WW Cet.
