What that may be?

Last nigh, while imaging Catalina from car park in Beaumaris, something went into one of my frames.. see attachment.

It seems that is is rotating (~4-5sec per rot), but it also seems it is blinking rapidly (like a disco ball )

Frames were 15sec long.. and there were 3 maximums in the whole frame.
Any ideas what that may be?

Iridium flare? Or one of the many tumbling / rotating satellites.

I am guessing tumbling satellite.
