Moon, Saturn, Jupiter in the dawn sky

Lined up to the east of the Sun are Mercury and Venus, down close to the horizon, and Saturn and Jupiter quite high.  The waning Moon is sliding down past them.

A detail from our “Zodiacal Wavy Chart” for 2019.
See the end note on enlarging illustrations.

The Moon overtakes Saturn on Friday March 29 at 6 Universal Time, which is from 4 to 7 hours earlier by North American clocks already on Daylight Shifting Time (5 to 7 hours earlier by more natural time), thus in the night.  By morning the Moon will be already to Saturn’s left.

The Moon’s route past Saturn is again close enough to cause an occultation, as on March 1.  This time it would be observable in the southern Atlantic.

The blue arrows mark the track of Saturn’s “shadow” cast by the Moon.  To the right is Saturn’s track past the Moon as seen from the center of the Earth.

Shortly afterwards, at 13 UT, the Moon is at its descending node across the ecliptic, on its way to pass south of the Sun on April 5.

DIAGRAMS in these posts are made with precision but have to be inserted in another format.  You may be able to enlarge them on your monitor.  One way: right-click, and choose “View image”, then enlarge.  Or choose “Copy image”, then put it on your desktop, then open it.  On an iPad or phone, use the finger gesture that enlarges (spreading with two fingers, or tapping and dragging with three fingers).  I am grateful to know of what methods work for you.

One thought on “Moon, Saturn, Jupiter in the dawn sky”

  1. Living in the Southern Hemisphere at the moment requires I adjust the perspective. Nonetheless great illustrations. Thank you
