This is the Griffith Observatory Sky Report for the period between September 1 and September 30, 2025. Here are the events happening in the sky of southern California.<\/p>\n

All times are in Pacific Daylight Time, PDT.<\/p>\n

The sun<\/strong> rises on the 1st<\/sup> at 6:27 a.m., and sets at 7:18 p.m. On the 30th<\/sup>, the sun rises at 6:47 a.m. and sets at 6:38 p.m.<\/p>\n

Mercury<\/strong> is close to the sun all month long and is not safe to observe. Do not observe any planet when it comes close to the sun, for the danger to the eyes is great.<\/p>\n

Venus<\/strong> rises in the east-northeast at 3:57 a.m., on the 1st<\/sup>, with a disk 84-percent illuminated and 12 arcseconds wide. On the 19th<\/sup>, Venus is about a degree west of the waning crescent moon. Both rise in the east-northeast around 4:30 a.m., PDT. On the 30th<\/sup>, Venus rises in the east at 4:53 a.m., PDT, with a disk 89-percent illuminated and 11 arcseconds wide.<\/p>\n

Mars<\/strong> is in Virgo the Maiden. Mars is close to sun all month long and is not safe to observe.<\/p>\n

Jupiter<\/strong> is in Gemini the Twins. On the 1st<\/sup>, the planet rises in the east-northeast at 2:21 a.m. The planet is 34 arcseconds wide. On the 30th<\/sup>, Jupiter rises at 12:48 a.m. 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.<\/p>\n

Saturn<\/strong> is in Pisces the Fishes. On the 1st<\/sup>, Saturn rises in the east at 8:15 p.m., and is 19 arcseconds wide. On the 3rd<\/sup>, Titan\u2019s shadow starts transiting Saturn\u2019s disk at 10:01 p.m. The transit ends on the 4th<\/sup>, at 1:48 a.m. Titan\u2019s shadow is about half an arcsecond in width, and a magnification of 300x or more is needed to see it. On the 30th<\/sup>, the planet rises at 6:15 p.m. The rings and Saturn\u2019s largest moon, Titan, can be seen with a telescope capable of magnification 50x.<\/p>\n

Uranus<\/strong> is in Taurus the Bull. On the 1st<\/sup>, the planet rises in the east-northeast at 11:04 p.m. On the 30th<\/sup>, Uranus rises at 9:09 p.m. On the 15th<\/sup>, Uranus is at Right Ascension 3h<\/sup> 57m<\/sup> 26s<\/sup> and declination of +20\u00b0 14\u02b9 27\u02ba. A magnification of 150x or more is needed to see the planet\u2019s 3.7-arcsecond disk.<\/p>\n

Neptune<\/strong> is in Pisces the Fishes. On the 1st<\/sup>, Neptune rises in the east at 8:14 p.m. On the 30th<\/sup>, Neptune rises at 6:18 p.m. On the 15th<\/sup>, Neptune is at Right Ascension 00h<\/sup> 05m<\/sup> 50s<\/sup> and declination of -00\u00b0 51\u02b9 51\u02ba. A magnification of 150x or more is needed to see the planet\u2019s 2.4-arcsecond disk.<\/p>\n

The moon is <\/strong>full on the 7th<\/sup>, last quarter on the 14th<\/sup>, new on the 21st<\/sup>, and first quarter on the 29th<\/sup>.<\/p>\n

SPECIAL EVENTS<\/strong><\/p>\n

Autumn begins<\/strong> and summer ends when the sun reaches the autumnal equinox on September 22 at 11:19 a.m. At this moment, the sun crosses the celestial equator from north to south on its journey along the ecliptic. The sun rises at 6:42 a.m., and sets at 6:49 p.m.. The day is 12 hours and seven minutes long. The days will continue to grow shorter, and the nights get longer, until the sun reaches the winter solstice on December 21.<\/p>\n

In the major lunar standstill of 2024-2025,<\/strong> the September southernmost moon rises as waxing gibbous on the 1st<\/sup> at 3:28 p.m., and sets on the 2nd<\/sup> at 12:54 a.m. The September northernmost moon rises at near last quarter at 11:06 p.m., on the 13th<\/sup>, and sets on the 14th<\/sup> at 2:35 p.m. Griffith Observatory will livestream broadcast the northern moonrise from Chimney Rock, Colorado on the 13th<\/sup>. On the 28th<\/sup>, the second southernmost moon sets at first quarter phase at 10:43 p.m., and rises on the 29th<\/sup> at 2:10 p.m.\u00a0 Griffith observatory is not planning any public event or web broadcast for this standstill.
