Venus, Mercury, Mars, and the star Regulus dance past each other in the eastern sky all month. Venus, at magnitude -3.9, dominates the show. Next in peak brightness is Mercury, of magnitude +2.2 to -1.3. Regulus is next in brightness at +1.4, with Mars last at +1.8.(Remember, negative numbers are brighter than positive numbers, and a low positive number, like 1 is much brighter than a magnitude 3. The dimmest star the unaided eye can see in a dark sky is about magnitude 6.)
Mars passes Regulus on Sept. 5. Mercury passes Regulus on September 10. Mercury is at greatest elongation, 18 degrees west of the Sun, on Sept. 12. Mercury gets 11 degrees to the lower left of Venus on Sept 14 before dropping back to the horizon. Mars and Mercury are closest to each other Sept 16. The mornings of Sept 17, 18, and 19, the thin crescent Moon joins the dance. Venus passes Regulus on Sept 19-20. At mid-month, Venus rises 2 hours 23 minutes before sunrise.
