Two occultations were recorded by John Broughton, One using CCD drift scan with a prepointed telescope and the other with a mobile unit using visual technique.

Discussion:

With two chords we can be confident that John's Reedy Creek location was north of the centerline of the event. The ellipse above is plotted at the best fit to John's observations of Hohensteina with the extra constraint that the ellipse axes have a ratio of no more than 1.09 as suggested by published parameters. This is less than this data suggests, however the published is flagged as Provisional and this plot is within the error bars so has good agreement. The misses by the rest of the team are consistent with the positive results.

The figures below show the drift-scan image of the occultation together and the data as analysed by John's Scanalyser software.

Unattended drift-scan observation. The trail and occultation is very
clear for an event involving a 12.7-magnitude star.

Comments:
I had positively identified the star and was ready but cloud prevented
earlier commencement.  There were definitely no events.

Clouded out 10 seconds after the expected event. I did get some
re-appearences later on, but my video record is incomplete
