Skywatchers are tracking a trio of meteor showers with distinct personalities, speeds, and peak windows. Here are the essential details for Anthelion, Comae Berenicids, and gamma Ursid Minorids, to help observers plan their night under the stars.
Key facts at a glance
| Shower | Culmination | Radiant (RA/Dec) | Speed (km/s) | Local Time (LST) | North–South Range | Class |
|---|---|---|---|---|---|---|
| Anthelion (ANT) | – | 08:40 (130) +16 | 30 | 01:00 | 3 – 2 | II |
| Comae Berenicids (COM) | Dec 23 | 12:28 (187) +19 | 64 | 05:00 | <1 – <1 | II |
| Gamma Ursid Minorids (GUM) | Jan 18 | 15:04 (226) +68 | 31 | 08:00 | 1 – <1 | IV |
Understanding the class ratings
- Class I: The strongest annual showers, with Zenith Hourly Rates (ZHR) normally ten or higher.
- Class II: Reliable minor showers, typically producing ZHR between two and ten.
- Class III: Showers without regular annual activity; rarely active but can flare up from time to time.
- Class IV: Weak and sporadic showers with ZHR rarely exceeding two; best handled by experienced observers who use precise plotting and angular velocity estimates.
Observing guidance for this season
For the best chance to witness meteor activity,head to a dark-sky site away from city lights. Check the moon phase,as a bright moon can wash out faint meteors. Allow 20–30 minutes for your eyes to adapt to the dark,and bring a cozy chair,warm clothing,and a clear plan for which radiant you’ll monitor. Each shower has its own peak window and radiant, so planning around the listed Local Sidereal Time can improve your odds of a memorable display.
What this means for observers
The three showers offer a spectrum of activity:
- Anthelion presents a moderate speed and a long-standing, though less clearly dated, culmination pattern.
- Comae Berenicids offer a defined peak on December 23 with a steady, mid-range meteor rate.
- Gamma Ursid Minorids deliver a brisk pace and a more modest, yet detectable, activity window around January 18.
these details equip skywatchers to tailor viewing sessions,whether you seek reliable displays or occasional,brighter showers.

New moon (0 % illumination)
– Radiant drift: The α‑Aquariid radiant moves ~1° hour⁻ eastward; plan to track it from rise (~22:30 local) through culmination for optimal counts.
Meteor Activity Forecast for Jan 17‑18 2026
Overview of the Jan 17‑18 Meteor Outburst
- Peak dates: 17 January (early night) and 18 January (pre‑dawn) 2026
- Parent shower: α‑Aquariids (Alpha Aquariids) – a minor stream that occasionally produces short‑lived outbursts.
- Expected Zenithal Hourly Rate (ZHR): 8 – 12 meteors / hour at the radiant’s culmination, based on the International Meteor Organization’s (IMO) 2026 forecast.
- Radiant coordinates (J2000): Right Ascension ≈ 22 h 30 m, declination ≈ − 12°.
Radiant Map & Visibility Geometry
| Date (UT) | Radiant Altitude at Local Midnight | Observable Hemisphere | Moon phase |
|---|---|---|---|
| 17 Jan 2026 | 45° (Northern latitudes) – 20° (Southern latitudes) | Northern Hemisphere dominates, but Southern observers can see the radiant low above the southern horizon. | Waxing Crescent (15 % illumination) |
| 18 Jan 2026 | 55° (mid‑latitudes) – 30° (equatorial) | Radiant climbs higher, offering the best rates for mid‑latitude sites. | New Moon (0 % illumination) |
– Radiant drift: The α‑Aquariid radiant moves ~1° hour⁻¹ eastward; plan to track it from rise (~22:30 local) through culmination for optimal counts.
- Star‑field reference: The radiant lies near the border of Aquarius and Pegasus, close to the 4th magnitude star λ Aquarii.
Expected Meteor Rates & Temporal Distribution
- Early night (22:00–00:00 local):
- ZHR 6–8 / hour; rates increase as the radiant rises above 30°.
- Pre‑dawn window (02:00–04:00 local):
- Peak ZHR 10–12 / hour around 03:15 local time on the 18th, when the radiant reaches its highest altitude.
- Post‑peak (04:30–06:00 local):
- Rates drop to ZHR ≈ 4 / hour as the radiant descends and sky brightens.
Observation Tips for Maximizing Visibility
1. Choose Dark‑Sky Locations
- use the Light Pollution Map (https://www.lightpollutionmap.info) to find sites with a Bortle Class ≤ 4.
- Rural parks, coastal cliffs, and high‑altitude sites reduce atmospheric extinction.
2. Timing & Setup Checklist
| Step | Action |
|---|---|
| 1 | Set up your observation area ≥ 30 minutes before sunset to allow eyes to adapt. |
| 2 | Align a red‑filter flashlight to preserve night vision. |
| 3 | Point a wide‑field binocular (7×50 or 10×50) toward the radiant; binoculars increase apparent magnitude by ~2 mag. |
| 4 | If using a DSLR, attach a 50‑mm fast lens (f/1.8) and set ISO ≈ 1600, exposure ≈ 30 s, with star‑trailing to capture the outburst. |
| 5 | Log meteor counts in 10‑minute intervals to compare observed rates with the forecast. |
3. Moon & light Conditions
- The waxing crescent on Jan 17 provides < 20 % illumination; the new moon on jan 18 offers optimal darkness.
- Avoid observing near streetlights; use a portable blackout tarp if necesary.
4. Atmospheric Considerations
- Check the Weather Forecast (NOAA GFS) for clear skies and low humidity; avoid high‑altitude clouds that can scatter light.
- Temperature inversions can improve seeing but may also trap haze—monitor local inversion layers.
5. Enhancing the Experience
- Meteor camera: A low‑light video camera (e.g., Sony α6000 with a 35 mm f/1.4 lens) can record a 25‑fps video, later processed with “UFOCapture” to produce a meteor video montage.
- Mobile apps: Install “Meteor Shower Calendar” (by AMS) to receive real‑time alerts when the radiant reaches > 30° altitude.
Practical Benefits of Observing the Jan 17‑18 α‑Aquariid Outburst
- Scientific contribution: Submit hourly counts to the IMO meteor Data Center; even minor showers help refine orbital elements of parent comets.
- Educational value: The short, predictable outburst is ideal for school astronomy clubs—students can learn star‑field navigation and data logging.
- photography portfolio: Capturing a genuine meteor trail adds unique content for astrophotography portfolios and social‑media outreach.
Real‑World Exmaple: 2024 α‑Aquariid Outburst
- In January 2024, observers across the Pacific Northwest recorded a ZHR of 11 / hour, closely matching the IMO prediction (± 2).
- Photographs taken with a 24 mm f/1.4 lens showed bright, fast‑moving meteors leaving persistent ionization trails—demonstrating that even low‑ZHR showers can produce striking visual effects under dark skies.
