A 14.039 second occultation was timed using video by Rick and Gordon Hudson at Pukerua Bay, NZ.
View the updated prediction.
Observers: 1 R & G Hudson, Pukerua Bay, NZ 2(M) D. Watson, Whakatane, NZ 3(P) Predicted Track M = Miss
Discussion:
The circle above is plotted at the expected 148km diameter of Hypatia.
The observation of the Hudsons indicates that the event was close to central for them, and suggests that the path shifted perhaps 1/3 of a track-width north from the updated prediction. Diana Watson in Whakatane was more than one track width further north. Although very favourable for the southern North Island of New Zealand, this event occurred at a time of year when many people were away on holiday. Otherwise it would be expected that at least two additional sites in the region would have reported a positive event.
