Hi,

The last outburst of SU UMa ended around Feb 17. It's now almost two months ago since SU UMa had an outburst... Has this been seen in the past?

Regards,

Eddy

Hi, 

What is going on with SU UMa? It's about 2,5 months since the last outburst!? Has the mass transfer rate considerably slowed down?

Regards,

Eddy

May I ask if there is a need for high cadence( <2 min exp) data of SU UMa during this standstill?

Hi Eddy,

You're right: SU UMa is acting oddly. Following the echo outburst following its last superoutburst, it dropped about 0.5 magnitudes below its normal low state and stayed there for about 20 days. The normal outburst around JD = 2458895 reset the star to its normal low state, but it's been "stuck" there for almost 100 days now. It seems like some time series would be useful in this odd state.

Now almost 4 months! ago since the last outburst... Has this ever been seen in SU UMa or in another dwarf nova? 

Cheers,

Eddy
