Sky Report
June, 2025
This is the Griffith Observatory Sky Report for the period between June 1 and June 30, 2025. Here are the events happening in the sky of southern California.
All times are in Pacific Daylight Time, PDT.
The sun rises on the 1st at 5:43 a.m., and sets at 8:00 p.m. On the 30th, the sun rises at 5:45 a.m. and sets at 8:09 p.m.
Mercury on the 1st is close to the sun and cannot be safely observed. On the 9th, the sun sets at 8:04 p.m., and Mercury sets in the west-northwest at 9:07 p.m., one hour three minutes later. The planet is 89-percent illuminated and 5.4 arcseconds wide. On the 30th, Mercury sets in the west-northwest at 9:45 p.m., one hour 36 minutes later. The planet is 46-percent illuminated and 7.5 arcseconds wide.
Venus rises in the east at 3:26 a.m. and is 50-percent illuminated and 24 arcseconds wide. On the 30th, Venus rises in the east-northeast at 3:04 a.m. and is 63-percent illuminated and 18 arcseconds wide.
Mars is in Leo the Lion. On the 1st, Mars sets in the west-northwest at 12:37 a.m. and is 91-percent illuminated and 5.5 arcseconds wide. On the 30th, Mars sets in the west-northwest at 11:24 p.m. and is 92-percent illuminated and 4.9 arcseconds wide. On the 29th at 6:15 p.m., Mars is only 17 arcminutes from the center of the 24-percent-illuminated waxing crescent moon, two arcminutes from the lunar limb. A magnification of over 150x is needed to see the planet’s small disk.
Jupiter moves from Taurus the Bull into Gemini the Twins on the 11th. On the 1st, Jupiter sets in the west-northwest at 9:13 p.m., one hour 13 minutes after the sun sets. On the 6th, the sun sets at 8:03 p.m., and Jupiter sets at 8:58 p.m., 55 minutes later. After the 6th, Jupiter is close to the sun and is not safe to observe. The planet is 34 arcseconds wide. A telescope capable of magnification 50x will show the Red Spot, and the four bright Galilean moons can be seen moving back and forth, across and behind Jupiter.
Saturn is in Pisces the Fishes. On the 1st, Saturn rises in the east at 2:20 a.m. On the 30th, the planet rises at 12:30 a.m. Saturn is 17 arcseconds wide. The rings and Saturn’s largest moon, Titan, can be seen with a telescope capable of magnification 50x. Saturn is about one degree south of Neptune in June.
Uranus is close to the sun on the 1st and not safe to observe. On the 6th, the planet rises in the east-northeast at 4:39 a.m., and the sun rises at 5:42 a.m., one hour three minutes later. On the 30th, Uranus rises at 3:09 a.m. On the 15th, Uranus is at Right Ascension 3h 46m 51s and declination of +19° 42ʹ 21ʺ. A magnification of 150x or more is needed to see the planet’s 3.5-arcsecond disk.
Neptune rises on the 1st in the east at 2:20 a.m. On the 30th, the planet rises at 12:27 a.m. On the 15th, Neptune is at Right Ascension 0h 9m 40s and declination of -0° 22ʹ 47ʺ. A magnification of 150x or more is needed to see the planet’s 2.3-arcsecond disk. Neptune is a degree north of Saturn all month long.
The moon is at first quarter on the 2nd, full moon on the 11th, last quarter on the 18th, and new moon on the 25th.
SPECIAL EVENTS
Summer begins in the northern hemisphere, and winter in the southern hemisphere, at 7:42 p.m. on June 20. At this precise moment, the sun reaches its northernmost point on the ecliptic. This point and the time the sun meets it are called the summer solstice. Summer ends with the autumnal equinox on September 22.
In the major lunar standstill of 2024-2025, the June southernmost moon sets as a full moon on the 11th at 5:36 a.m. No events are planned by Griffith for this event. Later that day, the southernmost moon rises as a 99-percent waning gibbous moon at 9:02 p.m. Griffith Observatory is planning on a public event at the observatory and a web broadcast for this standstill.

Lunar Calendar
June 1st to the 10th shows the Moon waxing which means more of its surface is illuminated. The Full Moon on the 11th ends this cycle. Starting from the 12th on, the Moon is waning. The First Quarter is on the 2nd, and the Last Quarter is on the 18th. June 25th marks the New Moon.
