[vsnet-alert 6866] RE: [vsnet-superoutburst 1171] 1RXS J232953.9+062814 outburst! (rebrightening?) - SUPEROUTBURSTING AGAIN

["Tonny Vanmunster" <Tonny.Vanmunster@advalvas.be>]

Dear colleagues,

A quick reply on Kato's message below (I have to leave the observatory for a
few hours now, a more detailed analysis will follow later today). The
rebrightening of 1RXS J232953.9+062814, that started on Nov 09/10, clearly
has developed into a superoutburst again, as I can derive from last night's
observations (Nov 10/11) at CBA Belgium Observatory. I was able to track the
object for 6.2 hours under perfect skies. The resulting light curve is truly
impressive, showing again 0.2 - 0.25 mag superhumps, superimposed by more or
less complex humps. Overall, there was also a definite fading trend.

I will further analyse the data, and distribute them later tonight. Please
continue monitoring this object !

Best regards,
Tonny Vanmunster
