[vsnet-alert 9556] V1060 Cyg: unusual double outburst

[Taichi Kato]

   As reported by Ed Wiley (the data include reports in cvnet-outburst),
the dwarf nova V1060 Cyg is undergoing an unusual "double outburst".
Although this object is likely a long-period system, the current
behavior deserves attention.  The behavior might be related to
double maxima in GK Per, BV Cen and other long-period systems.
CW Mon also shows a similar premaximum halt
(cf. http://adsabs.harvard.edu/abs/2003PASJ...55..491K )
(SS Cyg also showed double maxima during the very active 1998-1999
seasons, but the overall behavior is unlike present V1060 Cyg).
