Morning Sky

Jupiter and Saturn are the bright morning planets above the southeastern horizon during morning twilight.  Saturn is over 11° up in the sky.  Brighter Jupiter is 11.4° to the lower left of the Ringed Wonder.

One hour before sunrise, Jupiter is only 6° above the east-southeast horizon.  If you wait 15-20 minutes, you’ll see it a little higher in the sky.

The bright nearly, full moon illuminates the sky from low in the west. The lunar orb reaches its official full phase at 1:48 p.m. CDT.  The Old Farmer’s Almanac names March’s Full phase the “Worm Moon.”

Because of the moon’s brightness, use a binocular to see the starry background with the morning planets.  Saturn is 3.0° to the upper right of Theta Capricorni (θ Cap on the chart), while Jupiter is 4.6° to the lower left of Iota Capricorni (ι Cap).

Detailed Note: One hour before sunrise Saturn is over 11° above the southeastern horizon, 11.4° to the upper right of bright Jupiter. The Jovian Giant is over 6° up in the east-southeast.  Use a binocular to see the planets in front of the starry background.  Saturn is 3.0° to the upper right of θ Cap, while Jupiter is 4.6° to the lower left of ι Cap.  Farther west, the moon (15.0d, 100%) is nearly 14° up in the west.  Because of its brightness, block the moon’s glare to spot Eta Virginis (η Vir, m = 3.9), 3.3° to the lower left of the moon, and Porrima (γ Vir, m = 3.4), 7.6° to the upper left of the lunar orb.  The moon is Full (Worm Moon) at 1:48 p.m. CDT. One hour after sunset, the moon (15.6d, 100%) is less than 10° above the eastern horizon, 3.0° below Porrima.  Farther west, Mars – over 50° up in the west-southwest – is 2.3° above τ Tau and 3.6° to the lower right of ι Tau.  The planet is 9.0° below Elnath. Because of the bright moonlight, use a binocular to see Mars with the sidereal background.
