September is one of the year's most entertaining and awe-inspiring months to lay on your back on a dark hill and view the delights of the celestial dance in the sky above you as your ancestors once did on a nightly basis. Four of Sol's dance partners will be in the spotlight in September, 2010, taking part in a nightly dance that includes their less observable brothers and sisters, while Mercury will once again dance privately in the eastern sky each morning during September.
