This is the Griffith Observatory Sky Report for the period between October 1 and October 31, 2025. Here are the events happening in the sky of southern California.<\/p>\n

Mercury<\/strong> sets in the west at 7:11 p.m., PDT, on the 1st<\/sup>, and the sun sets at 6:37 p.m., PDT. The planet is 93-percent illuminated and 4.9 arcseconds wide.\u00a0 On the 31st<\/sup>, the sun sets at 6:01 p.m., PDT, and Mercury sets in the west-southwest at 7:05 p.m., PDT, one hour four minutes later. Mercury\u2019s disk is 61-percent illuminated and 6.8 arcseconds wide. A magnification of 150x is needed to see its disk. 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 at 4:55 a.m., PDT, on the 1st<\/sup>, and the sun rises at 6:48 a.m., PDT. The planet is 91-percent illuminated and 11 arcseconds wide. On the 31st<\/sup>, Venus rises in the east at 5:54 a.m., PDT, and the sun rises at 7:12 a.m., PDT, one hour 18 minutes later. The planet is 96-percent illuminated and ten arcseconds wide. A small telescope will show the disk with a magnification of 100x.<\/p>\n

Mars<\/strong> sets in the west-southwest at 7:51 a.m., PDT, on the 1st<\/sup>. On the 4th<\/sup>, the planet crosses from Virgo the Maiden into Libra the Scales. On the 31st<\/sup>, Mars sets at 6:58 p.m., PDT, 57 minutes after the sun sets. Mars is 99-percent illuminated and 4.0 arcseconds wide and is too small to reveal details on its disk<\/p>\n

Jupiter<\/strong>, on the 1st<\/sup>, rises in the east-northeast at 12:44 a.m., PDT. On the 31st<\/sup>, the planet rises at 10:54 p.m., PDT. Jupiter is 40 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.<\/p>\n

Saturn<\/strong>, on the 1st<\/sup>, rises in the east at 6:11 p.m., PDT. On the 31st<\/sup>, Saturn sets in the west at 3:54 a.m., PDT. The rings and Saturn\u2019s largest moon, Titan, can be seen with a telescope capable of magnification 50x.<\/p>\n

Uranus<\/strong>, on the 1st<\/sup>, rises in the east-northeast at 9:05 p.m., PDT. On the 31st<\/sup>, Uranus rises at 7:04 p.m., PDT. On the 15th<\/sup>, Uranus is at Right Ascension 3h<\/sup> 55m<\/sup> 3s<\/sup> and declination +20\u00b0 7\u02b9 26\u02ba. A magnification of 150x or more is needed to see the planet\u2019s 3.8-arcsecond disk.<\/p>\n

Neptune<\/strong>, on the 1st<\/sup>, rises in the east at 6:14 p.m., PDT, and the sun sets at 6:37 p.m., PDT. On the 31st<\/sup>, Neptune sets due west at 4:14 a.m., PDT. On the 15th<\/sup>, Neptune is at Right Ascension 0h<\/sup> 2m<\/sup> 51s<\/sup> and declination -1\u00b0 11\u02b9 17\u02ba. A magnification of 150x or more is needed to see the planet\u2019s 2.3-arcsecond disk.<\/p>\n

Full moon is on the 6th<\/sup>, last quarter on the 13th<\/sup>, new moon on the 21st<\/sup>, and first quarter on the 29th<\/sup>.<\/p>\n

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

The Orionid meteor shower<\/strong> is active from October 2nd<\/sup> to November 7th<\/sup>. The Orionids produce 10 to 20 shower members at maximum. The radiant is in the constellation Orion the Hunter. The parent object is the famous comet 1P\/Halley. The peak is on the night of October 20 to 21. The new moon will not interfere with observations.<\/p>\n

In the major lunar standstill of 2024-2025,<\/strong> the October northernmost moon rises in waning gibbous phase on the 11th<\/sup> at 9:59 p.m., PDT, and sets on the 12th<\/sup> at 1:27 p.m., PDT. Griffith Observatory will livestream broadcast this northernmost moonrise from Chimney Rock, Colorado, on October 11 and October 12. The October southernmost moon rises as a waxing crescent at 12:03 p.m., PDT, on the 26th<\/sup> and sets at 9:31 p.m., PDT. Griffith Observatory may broadcast this southernmost moonset.
