Mars will pass between Saturn and Spica this evening. Currently moving in retrograde, the red planet will be directly between the ringed planet and the star. All three will be close to 1st magnitude. Saturn and Spica are currently about 4.5° apart. Mars will be just under 2° from the star.
The trio will be close for a couple weeks. On the 21st a thin crescent Moon, 24% illuminated, will join to create a very nice quartet.
