Mercury to pass across face of sun

From Times Wire Reports
Mercury will transit, or pass across the face of, the sun Wednesday, an event that happens about 12 times per century.
Because the planet is so small compared with the sun, it will appear only 0.5% as wide. But observers using a small telescope equipped with a solar filter should find Mercury’s dark profile readily distinguishable from lighter sunspots.
The transit begins at 11:12 a.m. PST and can be viewed live online at www.exploratorium.edu/transit.
