Anomalous Behaviour of SU UMA ?

             Having decided not to go into super-outburst; SU UMA appears to have done, just that. Is such vacillation normal, or anomalous? The super-outburst we observed in April 2012, didn't exhibit this behaviour! Comments welcome, please.

Hello Bill,

Sometimes a normal outburst can 'trigger' a superoutburst, which is what appears to have happened with SU UMa here.  It's not common, but nor is it rare.  Stuff happening like this is why I observe CV's - expect the unexpected!

Happy New year!

Re Trigger.

Thanks Gary.

 

I should have got myself up this morning, but couldn't face the brilliant moonlight, or the cold. Also, was sure SU had gone for the time being! Like you say - “expect the unexpected”

 

Bill.

 

Best of the New Year to you, too.
