Mercury Transit Hawaiian Style Webcast
Transit of Mercury composite (10-minute intervals)
by M. Connelley and J. Walawender
On the morning of November 8, the planet Mercury passed directly in front
of the Sun. Because Hawaii was in the best position in the world to view
the entire event, IfA Science Education and Public Outreach Officer Gary
Fujihara organized a "Mercury Transit Hawaiian Style" webcast
to enable people throughout the world to view this event safely. IfA and
amateur astronomers on the summits of Haleakala and Mauna Kea used special
telescopes to transmit live images of the transit over the Internet.
The webcast included real-time images of the transit in a variety of wavelengths
of light. Interviews with IfA scientists, members of the Haleakala Amateur
Astronomers, staff of the Mauna Kea Visitor Information Station, and students
of University of Hawai'i at Hilo supplemented images of the transit.
To accommodate the heavy traffic, the webcast on the AstroDay website was
mirrored on the IfA website. The two sites had 150,000 hits over two days.
Sets of images have been compiled into time-lapse movies of the transit
to allow viewers to watch the five-hour transit in a few seconds.
The webcast was a collaboration of the IfA, the
Physics and Astronomy Department at the University of Hawaii at Hilo, and the Haleakala Amateur Astronomers.
