An 11 second occultation was recorded by Dave Gault, using video OSD technique.
One clearly observed miss was recorded for this event.

Observers: 1 D Gault,Kuriwa Observatory, NSW, AU 2(M) D Herald,Murrumbateman, NSW, AU 3(P) Prediction, TT14 28 June
The ellipse above is plotted at an arbitrary orientation to make the
longer axis fit the chord and the shorter axis adjusted to give the
same area as a circle with the same area as a circle with the
expected 89 km diameter of Havnia.
With only one chord it is not possible to determine whether Dave was north or south of the central line of the event so the plot has been centered on the chord.
However, assuming the updated prediction was approximately correct the greater than expected length of the chord would suggest that the path might lie close to the central portion of the asteroid.
The figure below shows the Tangra light curve of the occultation.
