Space‐based ultraviolet (UV) optical signatures of equatorial ionospheric bubbles have been computed from a first‐principles time‐dependent physical mesoscale ionospheric simulation model. We find that for nadir‐viewing geometry, extreme UV signatures at 911 Å of equatorial ionospheric bubble structures contain large bite‐outs in intensity, are structured over tens of kilometers scales, and are distinctly different from the signatures of the quiet ionosphere.
