Why don't you email the STEREO people and ask? They probably know where all the satellites are.

Hi P
That would be a dead pixel on the EUVI CCD detector. I don't know when
it appeared, but I can see it as far back as Jan 2010 and it is still
there now in the most recent data and in all wavelengths, meaning that
it is specific to the detector, and not one of the filters, for example.
There are a whole host of reasons why it can't be a satellite, the
primary one being that there aren't any out there where STEREO is
(which is a LONG way from Earth!), but also that a satellite would
need to be near the Sun in the several-million-degree corona, and be
absolutely huge (think: "that's no moon") to show up in focus in the
imagers like that.
So the dead-pixel thing is definitely the winner here
Always happy to help!
Best wishes,
Karl

Looks like a piece of dust on the surface of the CCD.

Absolutely not, never in a million years. They would most likely say it's a dust particle or microscopic hair. I expected the answer I got which is why I didn't want to bother emailing NASA, but it's really not much effort to try.

Agreed. Those satellites move and rotate often, if it were in space then it would appear in different locations. They should be wearing complete body suits in those clean room, but that still wouldn't stop dust from getting in there from items brought into those rooms over time.

Ok the NASA guy got back to me, and with such in depth detail and analysis too....
