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: JULY
By Erich Karkoschka
Venus is the “Evening Star” during dusk. Seven degrees ahead in the ecliptic is Mars, but 6 magnitudes fainter than Venus. On the 12th, Venus passes Mars only .5 degrees north. On the 20th, Venus passes Regulus at 1 degree distance. Mars follows behind Venus and passes Regulus on the 29th at only .6 degrees distance. Since they set at 8:30 pm, one has to watch this when it is still bright outside. Regulus should be visible. Mars is half magnitude fainter and will come into view then too.
Mars is close to Venus this month.
Saturn rises once it is dark and it stays up all night. Its opposition will be August 1st.
20 degrees east of Mars is Jupiter. Both planets form a large triangle with Fomalhaut well below them. This is best viewed in the morning when they are higher. The shape of this triangle will change as the distance between Jupiter and Saturn decreases over the summer. The right angle at Jupiter will become a larger angle.
Uranus and Neptune are morning planets.
Mercury has a short showing until July 22. It rises at 4 am below Castor and Pollux and does not come up high before twilight gets bright.
The Moon shortly after New Moon might be barely visible on the 10th. The next day, it will be beautifully paired with Venus to its left and Mars very close to Venus. Even on the 12th, the view will be worthwhile.
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).
