Observed. See. But no picture?

The best you would get is a diagram. In physics "observed" does not necessarily mean, in fact usually does not mean, seen in the sense of looking at the effect visually.

Observed via a sensor. Such as a microphone can observe a beep, or an accelerometer can observe a bump.

"See" does not imply "with eyeballs"

  While "see" seems like the obvious default sensory analogy to use for "detect" with a SQUID, now that I think about it, maybe it's more a synaesthestic blend of seeing, feeling and hearing.

The linked page has one. It is beautiful. What else do you want?

I agree. There are some pictures in the preprint https://arxiv.org/ftp/arxiv/papers/2202/2202.02798.pdf https://arxiv.org/ftp/arxiv/papers/2202/2202.02798.pdf (also https://www.weizmann.ac.il/condmat/superc/sites/condmat.superc/files/uploads/pdfs/2022/aharon-steinberg2022.pdf https://www.weizmann.ac.il/condmat/superc/sites/condmat.supe... linked by klyrs in other comment) The most relevant sentence is > The images were acquired with a pixel size of 13 nm, acquisition time of 40 ms/pixel, and image size of 430 × 305 pixels. Skip the text and look at figure 1, 2, 3, 4. The left column is the experimental data. The center column is the same image using a simulation. The right column is the same simulation showing the flow with arrows instead of shadows of red/blue. Figure 1 is made with gold. It's the normal behavior. When the electrons go up in the central "tube", they also go up in the "ears". Red means to the right and blue to the left. Figure 2 is made with a very very very pure superconductor. It's the strange new behaviors. When the electrons go up in the central "tube", they spin in the "ears". Note that the position of the red and blue parts are reversed. They only measured the red/blue values, and later fit the arrows in the simulation.
