Transit of Venus Special Event, 6 June 2012:
For the 7th time in Human history and last time this century, Venus will pass in front of the sun on 6 June 2012. We are encouraging hams to join up with astronomers and observers in public places to share in this event. It is observable worldwide except the center of the Atlantic (eastern S.America and western Africa) Everywhere else can see parts of it. It lasts 5+ hours and is fully visible around the Pacific Rim.
All previous centuries were before the discovery of radio and so sailing ships were dispatched around the globe to time the event. From these times, the size of the Solar System could be calculated. It took months if not years to get the data back. Now we can do it in 0.05 seconds with Ham radio.
See if you can contact hams at other Transit of Venus sites from your public observing site. Here are the suggested calling frequencies. We don't want contest-style pileups nor home stations. We just want a place where similar public setups can contact like minded other public viewing sites via ham radio and make their reports.
See the web page: http://aprs.org/VenusTransit2012.html
We are suggesting these calling frequencies:
40 Meters - 7180 KHz 20 Meters - 14240 KHz 17 Meters - 18140 KHz 15 Meters - 21240 KHz 12 Meters - 24940 KHz 10 Meters - 28340 KHz
VHF - APRS on the local national calling channel. Send APRS messages as noted on the web page.

It is observable worldwide except the center of the Atlantic (eastern S.America and western Africa) Everywhere else can see parts of it. It lasts 5+ hours and is fully visible around the Pacific Rim. In the Usa it is late afternoon on the 5th towards sunset.

FOr the Transit of Venus Event:
Event stations may join on DSTAR use reflector 1 CHARLIE. CHeck in and tell us how it is going. SOmeone please keep a written log of contacts?

Preliminary APRS Report:
There were 9 overall observation sites that checked in on APRS via the CQ VENUS (CQSRVR). These were identified:
Kyoto Japan - JH1IBN-7 (WB4APR) Kyoto U. Observatory, sunny! Canberra, AU - VK1NUT-8 - Mt Stromolo - cold,windy Australia - VK2AGC-2 Canada - VE6DSF Arizona, USA - K7TEJ-7 Italy - LA1TPA-7 Honolulu, HI - NH7WN Lexington, KY - W5IEM cloudy Arizona? - KD7ZWV Unknown? - KA2DDO
No one mentioned any HF contacts. We made one local contact on 10 meters, but were only running 5 W PEP.
The fact that both our Japan and Australian stations got good photos throughout, we should be able to reduce the data and repeat the original measurement of the size of the solar system! Though we expect the students might stretch out the data reduction over the next semester rather than zipping it out now over summer break!
Thanks to EVERYONE who participated. It shows the worldwide APRS connectivity potential. THough apparently our IGate in Japan was only 1 way, and we did not realize we were getting out until we got to the internet later and saw the traffic on the APRS-IS.
Lets get those Igates 2-way where legal!!
