NOVEMBER 2019 OBSERVING
Planetary Almanac

The Sun and planets are positioned for mid-November; the colored arrows show the motion of each during the month. The Moon is plotted for evening dates in the Americas when it’s waxing (right

side illuminated) or full, and for morning dates when it’s waning (left side). “Local time of transit” tells when (in Local Mean Time) objects cross the meridian — that is, when they appear due south and

at their highest — at mid-month. Transits occur an hour later on the 1st, and an hour earlier at month’s end.

The table above gives each object’s right ascension and declination (equinox 2000.0) at 0h Universal Time on selected dates,

and its elongation from the Sun in the morning (Mo) or evening (Ev) sky. Next are the visual magnitude and equatorial diameter.

(Saturn’s ring extent is 2.27 times its equatorial diameter.) Last are the percentage of a planet’s disk illuminated by the Sun and

the distance from Earth in astronomical units. (Based on the mean Earth–Sun distance, 1 a.u. is 149,597,871 kilometers, or

92,955,807 international miles.) For other dates, see skyandtelescope.com/almanac.

PLANET VISIBILITY Mercury: visible at dawn after the 18th • Venus: visible at dusk all

month • Mars: visible at dawn all month • Jupiter: visible at dusk all month • Saturn: visible at

dusk, sets early evening

PLANET DISKS have south up, to match the

view in many telescopes. Blue ticks indicate the

pole currently tilted toward Earth.
