What has been the most surprising discovery SDO has made thus far?

That is a tough one. Here is one surprising discovery for each of the instruments.

AIA: AIA observed a comet travel through the sun’s corona, travel behind the sun and emerge around the other side intact.

HMI: HMI has the first clear detection of emerging sunspots below the solar surface (visible layer called the photosphere) before there is any indication on the surface.

EVE: EVE scientists discovered extra energy in solar flares up to 5 hours after the peak of a flare.
