Ex-AR12699 To Return Within a Week? 27th February

Taking a look at the SOHO data for the far side of the sun it would seem that AR12699 that passed over the suns limb over a week ago that there are still signs of activity visible.  Loops to the centre of the disk opposite indicate a bipolar active region, and whilst maybe not as active of it's previous rotation there is hope there may still may be sunspots visible.  At the very least a region of plage visible in CaK wavelengths, and possibly white light, should be visible, with the ex-active region likely proceeded with the view of prominences on the solar limb a day or so before the (ex?) active region itself is actually visible.  However the area develops, or not, it gives solar observers something to look forward to seeing in the coming days ahead.
