Discussion:

The circle above is plotted at the expected 83 km diameter of Miriam. The predicted path is just visible in lower right corner. Jonathan was actually just outside the 1 sigma prediction line.
With only one chord it is not possible to determine whether Jonathan was north or south of the central line of the event. However, assuming the updated prediction was approximately correct the close match to the expected chord length, it would suggest that the chord might lie close to the central portion of the asteroid.

The figures below show the light curve of the occultation as analysed by Jonathan's Limovie software.
