3(P) Prediction, TT14 28 Sept
Discussion:
The circle above is plotted at the expected 63 km diameter of Hedda. With one chord and a contraining miss we can be confident of the path of Hedda and that it was north of the predicted line.
The figure below shows the Tangra light curve of Hristo's occultation.
The figure below shows the Limovie/Tangra light curve of Dave's constraining miss.
This is a good exaqmple of why we always want to hear about your definite misses as well as the positives.

The camera was acctually the new WAT-910BD. I
assume it has the same instrumental delays as WAT-910HX.
I will measure the delays with SEXTA in the next two weeks and will update the report if needed.
