Planets of the Month: AUGUST

By Erich Karkoschka

Mercury will start its visibility at dusk, but will never get very obvious. It remains close to the Sun.

Venus is the evening star during dusk. It passes Beta Virginis on the 13th at only 7 arc minutes in distance, similar to the distance between Jupiter and Saturn during the last winter solstice. But the faintness of the star will probably require binoculars to see it.

Saturn comes to opposition on August 2nd, when it rises at sunset. Around that time, its rings are very bright as compared to the planet.

Jupiter also comes to opposition this month on August 22nd. The evening before, the Full Moon will be right next to Jupiter.

On the evening of August 18th, the Moon occults Nunki, the second brightest star of the teapot asterism in Sagittarius. In Nogales, it will last from 7:47 to 8:01 pm, but in Tucson the Moon will not quite make it, although it will get very close to the star. In between there is a grazing occupation which is rare for such a bright star to get so close to us.
August is meteor month. The Perseids will peak on the night of August 11-12 when the Moon is next to Venus which sets early. It cannot be much better than that!! Look toward the east late evening or early morning toward the constellation Perseus.

Planets of the Month: MAY

by Erich Karksochka

Mercury and Venus are visible low in the west at dusk.  Mercury is almost 10 degrees higher than Venus and easier to see.  After
mid-month. their separation decreases and Venus appears far brighter than Mercury.  Mercury is visible naked eye until the 26th.  
On the 28th, as Mercury is stationary,  Venus passes by
at only half a degree distance.  In a telescope, their two disks
match in size, but Venus is 300 times brighter and 98 %
illuminated, Mercury only
13 % illuminated.
Mars is still an early evening planet, wandering through Gemini.
Jupiter rises before 2 am and comes about 30 degrees high during dawn. It is separated from Saturn by about 18 degrees.
Saturn rises before 2 am and comes about 30 degrees high during dawn. It is separated from Jupiter by about 18 degrees.
Vesta is still 7th magnitude in Leo, an easy object for binoculars.
During the morning of the 26th, the moon has its first total
eclipse in two years.  Totality is only 18 minutes long, just barely
getting fully into the Earth’s umbra, from 4:10 to 4:28, just as
dawn starts.  The setting moon partially eclipsed around
5:25 should be beautiful.
The moon is only a degree from Venus on the evening of the 12th.
Venus is easier to find than the moon since the moon is only 1 %
illuminated, Venus is essentially full.  If it is clear in the west,
the moon will be just barely visible naked eye.  Three days later, the
moon will be almost as close to Mars.

Grand Canyon Star Party

Join Tucson Amateur Astronomy Association and the National Park Service for the 32nd annual Star Party. The Star Party will be June 18 – 25, 2022. We average 50 telescopes for 8 nights. You will see Solar System planets, Galaxies Far Far Away, Star Clusters — some with several hundred thousand stars, Nebulae, multiple star systems (some with as many as 6 stars), and lots more. The skies are so dark you can clearly see the band of the Milky Way overhead. We start with a talk in the Visitor Center Auditorium about an astronomy topic at 8 pm. Observing at the telescopes goes from sunset (about 8 pm) to 11 pm. This event is free and open to anyone inside the Grand Canyon (park entrance fee required).  For additional information, check out our Grand Canyon Star Party Webpage at: https://tucsonastronomy.org/upcoming-events/grand-canyon-star-party/. or visit the Grand Canyon Star Party webpage at: https://www.nps.gov/grca/planyourvisit/grand-canyon-star-party.htm.
