By John Talbot, RANZ Occultation Group and Wellington Astronomical Society

Background I have been looking forward to this event for a long time. In the last 6 months I had prepared a plan for the Wel-lington Astronomical Society (WAS) to try to do a public viewing of the event in the Civic Square near the water front, where on a fine day there are always citizens and tourists walking or jogging at lunch time. The Central Library which is nearby had hosted us for some previous events and agreed that they would put on a display of some of their rare old books from the time of the 1769 transit when Lt James Cook was sent on the HMS Endeavour to Tahiti in the South Pacific to observe that event. They also set up a large screen TV so that people could watch the live feed being streamed from the NASA site at Moana Lua, in Hawaii. I also had to get permis-sion from the City Council to set up equipment in the square. Equipment I aimed to use the simplest equipment I could for the purpose to show that real science can be done with simple modern technology. I built a Sun Funnel for my small Meade telescope and tested it on the sun and was able to see several sunspots so I was confident I could see Venus on the day. I had heard about the Huddle method of measuring parallax and decided that aiming to take pictures at about 20 to 30 min intervals would give a suitable accuracy. My small old Nikon digital camera could take pictures and mark the time to 1 second accuracy which was close enough. I had 3 other members of WAS Bill Parkin, Lesley Hughes, and Roger Butrland ,organised to assist me and I made up some posters to display near observing site to explain what we were trying to do. Ten days out the weather forecast said it might be fine but as the days went by it became clear that at best we would have cloud. Transit Day The morning of the event was partly cloudy at my home 65 km from the site but as I drove south the rain front ar-rived and it did not stop raining all day. So we used our Plan B and put the telescope in the Library near the big TV and talked to people who stopped to watch. We had over 100 people spend some time with us and several took membership forms away with them so we hope to gain some new members for WAS. One part of New Zealand in the South West at a small town called Haast had fine weather and Martin Unwin is working through over 100 minutes of video that he was able to record. I look forward to his report in due course. When I got home my wife excitedly told me that she had seen the transit 4 times during the day through breaks in the clouds. She had even done a quick drawing of the time and position of one for me. And After Once I logged on to my PC the stream of results started coming in and soon turned to a torrent. As I write this 8 days after the event I have checked and recorded 22 reports some with up to 20 photographs. And I have another 36, mostly from Iran, that I still have to work through the details. In some cases I have asked for more details or photographs. If you have not submitted your observations yet and you have photographs taken at very near (+/- 5 seconds UTC) the 10:00 minute mark of time they would still be welcome.

Results so far The result s of so many and varied observers is naturally varied. For some this may be the first time they have tried to time an event of any kind and other may be experienced observers. The equipment reported has varied from a range of telescopes with filters or sun funnels, to special solar telescopes, to video cameras. And timing has varied from wrist watch to the nearest minute through to GPS inserted OSD time accurate to 20 milliseconds. As would be expected those with large telescopes with filters have the sharpest images and the lack Drop effect which makes timing so difficult for the 2nd and 3rd Contact points is barely present. The 1st and 4th contacts are harder to measure because there is effectively no remaining view of Venus to see at that time. This shows up in the average residual times for these points. For 1st & 4th contacts 62 seconds and for 2nd & 3rd contacts 17 seconds. The observed times are compared to the Occult predictions for each location. So far I have only managed to extract 3 midpoint estimates (expected to be between about 01:25 and 01:33 UTC) using the Huddle method. It turns out that the calculations will need a significant correction for results that were observed near sunrise (Iran) or sunset (New Zealand). This is made worse if there are no sample points on both sides of the midpoint which was not possible in Iran. The best result so far has a residual of just 6 seconds and was observed near San Francisco, USA where almost 4 hours of data at 10 minute intervals was recorded by Jeff Bald-win.

Results future As I work through this task I will send individual observers my analysis. When I get to the bottom of the pile I will summarise the results as I see them and see if we can extract the goal of the 1769 expeditions, the distance to the Sun. In other words can a bunch of mostly amateur observers get a result as good as if not better than they did. Of course we now have the luxury of knowing the “right” answer. Final Results When that is complete I will write this last chapter.
