In the Sky this Month for SWFL.
If you are new to the night sky, and have an Android device, such as a tablet or phone, you can find a free app in the Google Play Store, called Sky Map. Sky Map will help you locate objects in the night sky.
Sun is at solstice at 11:54 a.m. on 21st.
Moon: New – June 3; 1st Quarter – June 10; Perigee – June 7; Full – June 17; Last Quarter – June 25, Apogee – June 23.
Well after dusk in early June, earth shine will tend to make the unlit Moon more visible. At early evening on 5th, the Moon is 6° upper left of Mars. It is 4° above Regulus on the 8th.
Mercury (dusk, looking West-Northwest) starts June at 6° high ½ hour after sunset.
Venus (dawn) rises less than an hour before the Sun all month. At mid month,
it is about 5° above and left of Aldebaran.
Its magnitude is -3.8, but binoculars are probably needed due to the imminent sunrise.
Mars (dusk, looking West) is at 1.8 magnitude this month.
It sets almost 2¼ hours after the Sun in early June, and 1¼ hours after the Sun by the end of the month.
At twilight, binoculars may be helpful. As June ends, faint Mars is a little to the right of Mercury ½ hour after sunset, with twin starts Pollux and Castor to the right of Mars.
On the 17th & 18th, Mars and Mercury are only about ½° apart.
Jupiter (dusk – dawn, all night!, all month, Southeast) stays low in the Southern sky this month.
At mid month with the moon (nearly) full, Jupiter is southwest of the Moon on the 15th and northeast the next night an hour after sunset.
Jupiter is at opposition on June 10th, and brightens in June to -2.6, and grows to 46”. In fact, it is a bit larger and brighter than it has been in five years. On the 11th, from 11:34 p.m. – 12:37 a.m. EDT, two moon shadows are visible in a telescope.
As in May, it continues retrograde motion in June above the body of Scorpius on the horizon. This month it gets closer to Antares in Scorpius from 12° to 9°.
It retrogrades faster than Saturn this month and increases its separation from Saturn from 29°-31°. Saturn (late night – dawn all month, South) rises about 2.5 hours after sunset in early June, during dusk at the end of June. The magnitude changes from 0.3 –0.1, roughly the brightness of the star Vega.
Saturn is highest a few hours after midnight, so the rings are most visible in a telescope then.
At mid-June (~18th) it is close to the full Moon (17th) just
Saturn presses on to opposition, which occurs on July 9.
Uranus (early dawn) is still barely visible in June.

Neptune (early dawn) is still barely visible in June. See https://is.gd/urnep for a finder chart.
International Space Station: The ISS is visible mid/late (9-11p.m.) at night from the 3rd to the 10th and near dawn from the 24th to the 30th. See this link for specific times and routes for the
