Using the familiar setup, I recorded four frames and stacked them together. The smudge appears somewhat embering-glowing in SDO AIA 1600, but as a bright spot in AIA/SUVI 304.

The smudge predictor is an attempt to estimate where a smudge could be expected:

stretch(someMath(AIA 1600) – someMath(AIA 1700)),

flares and smudges might appear bright in the image.
