Mercury Transit 
Nov 15, 1999

Radio City
Mounds View, MN

The transit or passage of a planet across the disk of the Sun is a relatively unusual occurrence. As seen from Earth, only transits of Mercury and Venus are possible. On average, there are 13 transits of Mercury each century.

Leading the local effort were members of the MN ASTRONOMICAL SOCIETY, with help from MN Space Frontier,  and Radio City.
 

Remember NEVER look directly at the Sun!
