There has been an extratropical low west of the Canaries in the northeastern atlantic für some days. Now for me it looks like an subtropical system:

looks from the sat image that it still may be somewhat associated with a front, though there is a fair amount of convection near the center

And it looks like it's gone. Most of the convection has dried up and what little is left is far to the east of the circulation center:
