Jupiter is in front of the stars of Gemini with its bright stars Castor and Pollux nearby. Mars is in front of the dim constellation Cancer, 30 degrees to the lower left of Jupiter. Regulus (Leo) is 13 degrees below Mars.
Mars is rapidly moving eastward in its orbital motion around the sun. It passes about 1 degree from Regulus in October 15.
