Hawaii will be the premier place to view the transit of Venus; for the full seven hours of transit, the sun will be visible from the islands. Watch the live stream at the observatory.
From the Keck Observatory website: "The Transit of Venus will begin on Hawaii Island on Tuesday, June 5 at 12:10 p.m. and end at 6:44 p.m., Hawaiian Standard Time (3:10 pm to 9:44 pm PDT). Sunset is at 6:57 p.m."
If the live webcast of last year's asteroid 2005 YU55 flyby from the control room of Keck is anything to go by, the Hawaii coverage of the Venus transit will not disappoint!
As I'll be co-hosting a live transit event from Mount Wilson at the same time, Larry and I hope to link the two observatories via live feed so we can chat to solar and Venus experts and share the magic of this once-in-a-lifetime celestial event.
Twitter: If you're participating in the transit via Twitter, be sure to follow @astroengine (Ian O'Neill), @Discovery_Space, @AWB_org and @KeckObservatory for live updates. We'll also be keeping tabs on the hashtags #TOV2012, #VenusTransit and #AWBTOV (specifically for the Mt. Wilson transit event), so be sure to get involved in the Venus transit conversation!
