[vsnet-alert 25267] Re: VX For: possible superoutburst (since Jan. 17)

[Keisuke Isogai]

Hi all,

In the 2009 superoutburst, this object showed five rebrightenings.
The rebrightening type and the superhump period of 0.061327 d
imply that this object is a good candidate for a period bouncer, but
the early superhump and growing superhump have not been observed
yet. Time-series observations are strongly encouraged to confirm the
system parameters.

Best,
Keisuke Isogai
