Skywatch Alert: Meteors, Auroras & ISS Sighting to Light Up Oct 1–2, 2025

Key Facts Meteor Showers & Comets Early October brings two modest meteor showers. The Orionids, active Sept 26–Nov 7, begin in earnest on Oct 2 amsmeteors.org starwalk.space. NASA notes the Orionids arise from “debris trailing behind Halley’s Comet” and typically yield ~10–20 meteors/hr at peak science.nasa.gov. (Peak viewing is mid-Oct, but with the New Moon on Oct 21–22 the sky will be dark.) Meanwhile, the Southern Taurids (active Sept 20–Nov 20) are underway; these slow meteors from Comet 2P/Encke are rich in bright fireballs amsmeteors.org. Note the sky will be fairly bright around Oct 1–2 (Moon ~¾ full in-the-sky.org), so expect

Interstellar Comet 3I/ATLAS: A Visitor from Beyond the Solar System

Mysterious Manhattan-Sized Interstellar Object 3I/ATLAS Sparks Alien Theories Ahead of Halloween

Manhattan-Sized Visitor: Alien Mothership or Giant Comet? Discovery and Orbit Astronomers first spotted 3I/ATLAS on July 1, 2025, when the ATLAS asteroid survey telescope in Chile reported a fast-moving fuzzy object science.nasa.gov science.nasa.gov. Archived images quickly confirmed it follows a steep, open-ended (hyperbolic) path – a clear sign it was not born in our Solar System. NASA confirms that 3I/ATLAS is the third known interstellar visitor (after 1I/ʻOumuamua in 2017 and 2I/Borisov in 2019) science.nasa.gov science.nasa.gov. From its inbound direction near the constellation Sagittarius, it likely originated far from the Sun, perhaps even from the galactic center region science.nasa.gov. This

This cosmic interloper – formally designated 3I/ATLAS (with “3I” signifying the third interstellar object ever recorded) – was first detected on July 1, 2025 by the NASA-funded ATLAS survey telescope in Río Hurtado, Chile reuters.com esa.int. Its discovery was quickly confirmed by observatories worldwide when its highly eccentric trajectory signaled an origin beyond our Solar System esa.int. Every other comet, asteroid, planet, and moon we’ve observed shares a common birth in
Cosmic Skywatch Alert: Geomagnetic Storms, Shooting Stars & Comets Light Up Late Sep–Early Oct 2025

Cosmic Skywatch Alert: Geomagnetic Storms, Shooting Stars & Comets Light Up Late Sep–Early Oct 2025

Space Weather & Aurora Forecast NOAA forecasts a Strong (G3) geomagnetic storm on Sept 30, 2025. According to SWPC, “G3 (Strong) geomagnetic storming is expected through 30/1200 UTC due to CME influences” swpc.noaa.gov. This follows an M6.4-class solar flare on Sept 29 (from active Region 4232), which caused an R2-level radio blackout swpc.noaa.gov. Aurora experts note that such storms can power dazzling Northern Lights. The peak storming late Sept 30 (early Oct 1 UT) means northern skies may glow. “Quiet to active” conditions are forecast after the storm, so Sept 30 is the prime aurora night. (Skywatchers should watch real-time SWPC

Falcon 9’s ‘Jellyfish’ Launch & Webb’s Moon-Forming Disk – Space News Roundup (Sept 29–30, 2025)

Falcon 9’s ‘Jellyfish’ Launch & Webb’s Moon-Forming Disk – Space News Roundup (Sept 29–30, 2025)

Key Facts SpaceX & Other Launch Highlights SpaceX capped September with a spectacular twilight launch. On Sept. 28 (local time), a Falcon 9 lifted off from Vandenberg SFB carrying 28 Starlink v2 Mini satellites space.com. Reaching dusk, the rocket’s exhaust expanded into the upper atmosphere and caught the Sun’s rays, creating a brilliant “space jellyfish” effect visible from hundreds of miles. Space.com’s Brett Tingley, camping in Afton Canyon (Mojave), marveled, “I’ve seen plenty of Falcon 9 ‘jellyfish’ online but never in person. It was lit up gorgeously from below by the setting sun…” space.com. The booster landed on the drone ship “Of Course

October 2025 Sky Spectacular: Harvest Supermoon, Orionid Meteor Shower and Comet Frenzy

A Rare October Super Harvest Moon October’s full Moon (Oct 6 local dates) coincides with lunar perigee (closest approach), making it a supermoon – the largest of 2025 nationalgeographic.com the-independent.com. It is also the Harvest Moon, by definition the full moon nearest the autumnal equinox. However, in 2025 the timing is unusual: unlike most years when the Harvest Moon falls in September, this year it slips into October. Space.com explains that “the full moon of Oct. 6… will also carry the title ‘Harvest Moon’” because it actually lies closer to the Sept 23 equinox than September’s full moon space.com. According to

Skywatch Alert: Aurora, Meteor Showers & Satellite Sights – What to See Sept 29–30, 2025

Space Weather Forecast Space weather experts agree: late September will be mostly uneventful. NOAA’s SWPC issued a 3-day forecast on Sept 29 predicting only quiet to unsettled geomagnetic conditions (Kp indices up to 4) services.swpc.noaa.gov. In its rationale NOAA explicitly notes “No G1 (Minor) or greater geomagnetic storms are expected” on Sept 29–30 services.swpc.noaa.gov. EarthSky’s “Sun News” bulletin echoed this outlook, describing Sept 29–30 as “Quiet to unsettled” as the effects of a coronal-hole high-speed stream (CH HSS) wane earthsky.org. Space.com’s aurora live-blog (Sept 25 update) had warned that a small solar wind boost over the weekend might briefly push

Cosmic Showcase: What’s Up in the Sky on Sept 28–29, 2025

Meteor Showers and Fireballs This weekend’s meteor activity will be modest. No major shower peaks on Sept 28–29. The Orionids (parent comet Halley) have just started but are weak – current rates are well under 1 meteor/hour and won’t peak until Oct. 23 amsmeteors.org. The only notable shower is the Southern Taurids (from comet 2P/Encke), active Sept 23–Nov 12 with a broad radiant. AMS predicts a Southern Taurid rate of about 3/hour around local midnight (the radiant in Pisces, best near 1 a.m.) amsmeteors.org. All other named showers (epsilon Geminids, sextantids, etc.) are producing <1/hr amsmeteors.org amsmeteors.org. Thus most meteors will be

Incredible Skywatch Weekend: Northern Lights, Meteor Fireballs & Planetary Sights (Sept 27–28, 2025)

Key Facts Solar Storms and Aurora Outlook Space weather officials are on alert for auroras this weekend. A large coronal hole on the Sun has rotated into an Earth-facing position, sending a stream of fast solar wind toward Earth. According to NOAA’s Space Weather Prediction Center, this “weak enhancement in the solar wind” is forecast to arrive and push geomagnetic activity to unsettled or even active levels, with a chance of minor G1 storms space.com. In practical terms, that means the Northern Lights could strengthen on the nights of Sept. 27–28. If the disturbance reaches G1 (Kp 5) levels, auroras
