Throughout all of 20 May 2010, I've been monitoring a very small feature
showing up in the SDO AIA images, and then in the MDI Magnetogram images.
Here are a few examples.  The small area appears to have the markings of
an active sunspot region, albeit rather small.  However, it appears to be
growing.  Will it become an official spot, soon?  It is worth watching.

Here are some examples:

Additionally, STEREO indicates the possible return of active region 1069
in approximately two days' time.
