SUMMARY OF PLANETS IN 2022 MORNING SKY

This morning, Venus passes between the horns of Taurus, a precarious place to be, before daybreak.

The brilliant Morning Star rises nearly two hours before sunup.  An hour later, it is about 9° above the east-northeast horizon, 1.5° to the upper left of Zeta Tauri (ζ Tau on the chart) – the southern horn of Taurus – and 6.4° to the lower right of Elnath, the northern horn.  A binocular may be needed to see dimmer Zeta.

The head of Taurus is made of Aldebaran – nearly 15° to the upper right of Venus – and the Hyades star cluster.  The Pleiades star cluster, about one-third of the way up in the east, rides on the back of the Bull.

2022, July 13: Bright Jupiter and Mars are in the southeastern sky before sunrise.

Three other planets are visible this morning as part of the morning planet parade.  Bright Jupiter is about halfway up in the southeast.  Dimmer Mars is to its lower left in the east-southeast.  Saturn is in the south-southwest.

Saturn is the dimmest of the four bright morning planets.  The Ringed Wonder is less than one-third of the way up in the sky above the south-southwest horizon.  It is retrograding in eastern Capricornus, near the star Deneb Algedi.

The perigee Full moon is known in the popular press as a “supermoon” – the Full moon that occurs near perigee.  The Farmer’s Almanac calls the July Full moon the “Buck Moon”

The supermoon is so named when the Full phase occurs when the moon is at least 90% of its perigee distance. This occurs a few times each year.  It’s supposed to be super large and super bright.  The perigee moon is about 14% closer and 14% brighter than the moon’s typical distance.

First 14% is not so much brighter than the typical Full moon and likely not visible to the human eye.

Can you tell the which image is 4% bigger than the other image -- difference between a typical full moon and a "supermoon?"
Can you tell the which image is 14% bigger than the other image — difference between a typical full moon and a “supermoon?”

Secondly, take a look at these two images.  One is 14% larger than the other one.  Can you tell the difference?

When the popular press advertises any celestial event that encourages the public to look up, that is excellent publicity for sky watching.  The difference from tonight’s Full moon and another is not likely visible.

Please get outside enjoy the bright Full moon.  Take a walk in the bright moonlight.  Watch and listen for the night sounds of nature.
