Georgia Tech Observatory Ready for Mercury Transit

Primary tabs

On Monday, Nov. 11, 2019, the planet Mercury will pass across the disk of the sun. This planetary transit is rare, occurring only around 13 times each century. “This will be the last such event visible from Georgia Tech until 2049,” says James Sowell, director of the Georgia Tech Observatory.

The transit begins at 7:36 AM and ends at 1:04 PM.

Because Mercury is so small, its passage across the sun could be seen only with magnification coupled with the same safety precautions when viewing a solar eclipse. 

The Georgia Tech Observatory will set up eye-safe telescopes in front of the Howey Building, by the Seven Bridges plaza, during the entirety of the transit. “The skies must be rather free of clouds in order to witness the event,” Sowell says.
