Daylight<br \/>shortens from 11:31 (11.524 hours) on 1 October to 09:16 (9.269 hours) on 31<br \/>October so we gain 2 hours and 15 minutes of night time, by the end of the<br \/>month.<\/p>\n<p>The Moon begins the month in Sagittarius (The Archer) and ends in Aquarius (The<br \/>Water Bearer) coming closer to Earth by 16,643 km. The full Hunter\u2019s Moon<br \/>appears first on 7 October at 4:48 am in Pisces (The Fishes). Since it is at<br \/>\u2018perigee syzygy\u2019, it is also a supermoon so fishing folk can expect larger<br \/>tides. Lunar perigee (closest to Earth) on 8 October at 1:46 pm finds the Moon<br \/>some 359,808 km away from Earth\u2014around 24,592 km closer than<br \/>average\u2014subtending an angle of 33.2 arc-minutes. This is followed by last<br \/>quarter on 13 October at 7:13 pm in Gemini (The Twins). The new Moon appears on<br \/>21 October at 1:25 pm in Virgo (The Maiden) beginning a new synodic (Lunar)<br \/>month which will last 29 days, 18 hours and 22 minutes. Lunar apogee (furthest<br \/>from Earth) occurs on 24 October at 12:44 am and takes the Moon to 406,462 km<br \/>away from Earth\u2014around 22,062 km further than average\u2014subtending an angle<br \/>of 29.4 arc-minutes. Finally, the first quarter of the new Lunar cycle shows up<br \/>on 29 October at 4:21 pm in Capricornus (The Sea Goat).<\/p>\n<p>On 10 October, the Pleiades in Taurus (The Bull) will be 0.9 degrees south of the<br \/>waning gibbous Moon before sunrise. On 13 October, the first quarter Moon will<br \/>rise between Pollux and Jupiter in Gemini (The Twins) just before midnight.<\/p>\n<p>For the inferior planets: Mercury begins the month in Virgo (The Maiden) and<br \/>ends in Scorpio (The Scorpion) but comes closer by 58,760,922 km (0.39AU). The<br \/>\u2018Swift Planet\u2019 decreases in magnitude from -0.52 to -0.10 (1.47 times in<br \/>brightness). Mercury passes through another aphelion (furthest from the Sun) on<br \/>10 October and reaches greatest eastern elongation on 29 October. Venus begins<br \/>the month in Leo (The Lion) and ends in Virgo (The Maiden) but recedes by<br \/>16,544,626 km (0.11AU). The \u2018Morning Star Planet\u2019 lives up to the epithet by<br \/>shining brightly, but low in the eastern sky, at -3.9 magnitudes in the hour<br \/>before sunrise. Venus reaches perihelion (closest to the Sun) on 2 October.<\/p>\n<p>For the superior planets: Mars begins the month in Virgo (The Maiden) and ends<br \/>in Libra (The Scales) but recedes by 7,891,929 km (0.05AU). The \u2018Red Planet\u2019<br \/>Mars increases in magnitude from 1.57 to 1.46 (1.11 times in brightness)<br \/>throughout October. Jupiter remains in Gemini (The Twins) all month but comes<br \/>closer by 70,873,488 km (0.47AU). The \u2018Gas Giant\u2019 increases in magnitude from<br \/>-2.12 to -2.32 (1.20 times in brightness) over the month. Jupiter reaches<br \/>western quadrature on 17 October meaning the angle between Sun, Earth and<br \/>planet is exactly 90 degrees.<\/p>\n<p>Saturn begins the month in Pisces (The Fishes) and ends in Aquarius (The Water<br \/>Bearer) but recedes by 33,997,930 km (0.23AU). The \u2018Ringed Planet\u2019 decreases in<br \/>magnitude from 0.62 to 0.77 (1.15 times in brightness) over October. On 6<br \/>October, Saturn will be 3.8 degrees south of the full Moon in the small hours.<br \/>Uranus remains in Taurus (The Bull) but comes closer by 47,171,766 km (0.32AU).<br \/>Neptune remains in Pisces (The Fishes) but recedes by 32,086,578 km (0.22AU).<\/p>\n<p>There are 6 meteor showers visible in October as detailed in the ephemeris.<br \/>Observability is a balance between \u2018zenith hourly rate\u2019 (the number of shooting<br \/>stars per hour if the radiant point were directly overhead) and Moon<br \/>illumination. So, we can rule out the Camelopardalids (281 OCT), the Draconids<br \/>(009 DRA) and the delta-Aurigids (224 DAU) because of a combination of both<br \/>factors. The epsilon-Geminids (023 EGE) has a very low ZHR but the waning<br \/>crescent Moon is illuminated to only 10%. It might be worth checking them out<br \/>on 18 October.<\/p>\n<p>Our best show is reserved for the Orionids (008 ORI), peaking on 20 October,<br \/>with a ZHR of 20. The waning crescent Moon is barely illuminated as the new<br \/>Moon appears within half a day so viewing should be excellent. The parent comet<br \/>is the most famous of them all: 1\/P Halley. The radiant point is close to<br \/>another famous object: Betelgeuse in Orion (The Hunter).<\/p>\n<p>Finally, on 24 October we have the Leonis Minorid (022 LMI) meteor shower with<br \/>a ZHR of 2. This meteor shower has the distinction of being the first found in<br \/>photographic orbital data and the parent body is comet C\/1739 K1 (Zanotti). The<br \/>radiant point is between the hind legs of Ursa Major (The Great Bear) so is<br \/>circumpolar. Although activity is low, the waxing crescent Moon is still<br \/>emerging from new so is illuminated only 9%.<\/p>\n<p>20\u201323 October could be spectacular observing nights if the Edinburgh and<br \/>Lothian weather behaves. Not only could we witness the peak of the Orionids<br \/>mentioned above but two comets may reach naked-eye brightness. First comet<br \/>C\/2025 R2 (SWAN)\u2014only discovered on 12 September\u2014will be 0.27 AU from the<br \/>Earth in Sagittarius (The Archer). Comet C\/2025 A6 (Lemmon) will be 0.6 AU from<br \/>Earth in Serpens Cauda (The Serpent\u2019s Head). Both comets should be viewed a<br \/>couple of hours after sunset. Not visible is our cosmic interloper, comet<br \/>3I\/ATLAS, which passes perihelion on 29 October at 11:44 am.<\/p>\n<p>At the time of our sky map, some constellations visible are Cepheus (The King)<br \/>at zenith, Ursa Major (The Great Bear) in the north, Perseus (The Hero) in the<br \/>east, Corona Borealis (The Northern Crown) in the west (which contains our<br \/>elusive recurrent nova known as the Blaze star) and Pegasus (The Winged Horse)<br \/>in the south. The ecliptic hosts Taurus (The Bull), Aries (The Ram), Pisces<br \/>(The Fishes), Aquarius (The Water Bearer), Capricorn (The Sea Goat) and<br \/>Sagittarius (The Archer).<\/p>\n<p>The \u2018Summer Triangle\u2019\u2014Vega in Lyra (The Lyre), Altair in Aquila (The Eagle)<br \/>and Deneb in Cygnus (The Swan)\u2014is prominent in the south-west. The \u2018Winter<br \/>Triangle\u2019\u2014Procyon in Canis Minor (The Lesser Dog), Sirius in Canis Major (The<br \/>Greater Dog) and Betelgeuse in Orion (The Hunter) rises in the wee, small<br \/>hours. Circumpolar constellations\u2014always above the horizon\u2014include<br \/>Camelopardalis (The Giraffe), Cassiopeia (The Seated Queen) and Draco (The<br \/>Dragon).<\/p>\n<p><img fetchpriority=\"high\" decoding=\"async\" width=\"612\" height=\"792\" data-attachment-id=\"616143\" data-permalink=\"https:\/\/theedinburghreporter.co.uk\/2025\/09\/the-astronomical-sky-above-edinburgh-and-lothian-in-october\/ephemeris-11\/\" data-orig-file=\"https:\/\/www.europesays.com\/uk\/wp-content\/uploads\/2025\/09\/w=612.jpeg,h=792\" data-orig-size=\"612,792\" data-comments-opened=\"1\" data-image-meta=\"{&quot;aperture&quot;:&quot;0&quot;,&quot;credit&quot;:&quot;&quot;,&quot;camera&quot;:&quot;&quot;,&quot;caption&quot;:&quot;&quot;,&quot;created_timestamp&quot;:&quot;0&quot;,&quot;copyright&quot;:&quot;&quot;,&quot;focal_length&quot;:&quot;0&quot;,&quot;iso&quot;:&quot;0&quot;,&quot;shutter_speed&quot;:&quot;0&quot;,&quot;title&quot;:&quot;&quot;,&quot;orientation&quot;:&quot;0&quot;}\" data-image-title=\"Ephemeris\" data-image-description=\"\" data-image-caption=\"\" data-medium-file=\"https:\/\/imagedelivery.net\/F92qk9bnhVOT8KcXbWkWyg\/theedinburghreporter.co.uk\/2025\/09\/Ephemeris.jpg\/w=232,h=300\" data-large-file=\"https:\/\/www.europesays.com\/uk\/wp-content\/uploads\/2025\/09\/w=612.jpeg,h=792\" src=\"https:\/\/www.europesays.com\/uk\/wp-content\/uploads\/2025\/09\/w=612.jpeg\" alt=\"\" class=\"wp-image-616143\"  \/><\/p>\n<p><img loading=\"lazy\" decoding=\"async\" width=\"970\" height=\"1024\" data-attachment-id=\"616141\" data-permalink=\"https:\/\/theedinburghreporter.co.uk\/2025\/09\/the-astronomical-sky-above-edinburgh-and-lothian-in-october\/20251001_edinburghreporter\/\" data-orig-file=\"https:\/\/imagedelivery.net\/F92qk9bnhVOT8KcXbWkWyg\/theedinburghreporter.co.uk\/2025\/09\/20251001_EdinburghReporter.png\/w=1800,h=1900\" data-orig-size=\"1800,1900\" data-comments-opened=\"1\" data-image-meta=\"{&quot;aperture&quot;:&quot;0&quot;,&quot;credit&quot;:&quot;&quot;,&quot;camera&quot;:&quot;&quot;,&quot;caption&quot;:&quot;&quot;,&quot;created_timestamp&quot;:&quot;0&quot;,&quot;copyright&quot;:&quot;&quot;,&quot;focal_length&quot;:&quot;0&quot;,&quot;iso&quot;:&quot;0&quot;,&quot;shutter_speed&quot;:&quot;0&quot;,&quot;title&quot;:&quot;&quot;,&quot;orientation&quot;:&quot;0&quot;}\" data-image-title=\"20251001_EdinburghReporter\" data-image-description=\"\" data-image-caption=\"\" data-medium-file=\"https:\/\/imagedelivery.net\/F92qk9bnhVOT8KcXbWkWyg\/theedinburghreporter.co.uk\/2025\/09\/20251001_EdinburghReporter.png\/w=284,h=300\" data-large-file=\"https:\/\/imagedelivery.net\/F92qk9bnhVOT8KcXbWkWyg\/theedinburghreporter.co.uk\/2025\/09\/20251001_EdinburghReporter.png\/w=696,h=735\" src=\"https:\/\/www.europesays.com\/uk\/wp-content\/uploads\/2025\/09\/w=970.png\" alt=\"\" class=\"wp-image-616141\"  \/><\/p>\n<p><a class=\"m-a-box-avatar-url\" href=\"https:\/\/theedinburghreporter.co.uk\/author\/philip-daly\/\" target=\"_blank\" rel=\"noopener\"><img loading=\"lazy\" decoding=\"async\" alt=\"\" src=\"https:\/\/www.europesays.com\/uk\/wp-content\/uploads\/2025\/09\/5d909525f46735ff960bbf4941aecaa4846be89f56e924659ce9bc2266db9f73\"  class=\"avatar avatar-100 photo\" height=\"100\" width=\"100\" itemprop=\"image\"\/><\/a><\/p>\n<p>Phil Daly is a former employee of the Royal Observatory Edinburgh (now UKATC) on Blackford Hill.<br \/>He has worked on the UK&#8217;s overseas telescopes in Hawaii (UKIRT, JCMT) and on large telescopes<br \/>at major astronomical observatories worldwide.
