A 2.0 second occultation was recorded by Paul D. Maley and L.Palmer, E, in Thuwal, Saudi Arabia , using video OSD technique. They were part of an expedition with members from King Abdulaziz University to observe

Four clearly observed misses were recorded for this event, One of which clearly constrains the solution. and Two members of the expedition had equipment problems, One of which may have been in the shadow path.

Discussion:

The circle above is plotted at the expected 43 km diameter of Dagmar. With one chord and constraining miss (5), we can be confident of the path of Dagmar and that it was very close to the predicted line (8), dotted.

The figure below shows the Limovie light curve of Paul's occultation.
