Sorry I misread the name. This is SW UMA not SU Uma. Still waiting for an outburst of SU UMa

SU UMa is now reported to be in outburst after an unusually long gap. (I must be clairvoyant :lol: )

This is the first outburst I have seen since 17 Feb 2020 which represents a remarkable spell of 126 days between outbursts.
