November 2017 brought several notable meteor showers, offering sky watchers multiple opportunities to observe bright streaks across the night sky. During this month, the Orionid shower peaked, delivering reliable activity for observers in both hemispheres.
Below is a quick-reference table summarizing the key meteor showers and conditions for November 2017, including peak dates, zenithal hourly rates, and Moon interference levels.
| Meteor Shower | Peak Activity (2017) | Zenithal Hourly Rate (ZHR) | Moon Interference |
|---|---|---|---|
| Orionids | 20–22 October, sustained activity into early November | 15–20 | Waning gibbous, moderate interference after midnight |
| South Taurids | 10–15 November | 8–10 | Waning crescent, favorable late month |
| Northern Taurids | 10–15 November | 5–8 | Waning crescent, favorable late month |
| Leonids (yearly background) | Active through mid-November | Minimal, waning moon after mid-month |
Observing Orionids in November 2017
The Orionid meteor shower, originating from debris of Comet Halley, remained active into early November 2017, with rates gradually declining after the October peak. Observers in mid-northern and southern latitudes could still expect roughly 10–15 meteors per hour under dark skies during the first week of November.
Best viewing occurred between midnight and dawn, when Orion rose higher in the southeastern sky. The waning gibbous Moon rose late in the evening, washing out fainter streaks during the first half of the night, so timing observations after moonset improved the experience.
Taurid Activity and Fireball Potential
South and Northern Taurids Overview
Both the South and Northern Taurids peaked around 10–15 November 2017, producing a modest but steady number of meteors. These showers are known for bright fireballs that can linger longer than typical meteor streaks, making them favorites among photographers and patient observers.
Fireball Events in Late November
Although the Taurids delivered relatively low counts, the reduced moonlight toward late November created darker skies ideal for spotting larger fragments. Amateur astronomers reported several bright fireballs on 17–20 November, attributed to the South Taurid stream.
Planning Your Meteor Watching Sessions
Successful viewing in November depended on location, timing, and local weather conditions. Choosing sites with minimal artificial light, giving eyes 20–30 minutes to adapt, and facing the correct radiant increased the likelihood of sightings.
- Check local moonrise and moonset times to avoid bright lunar interference
- Focus on early morning hours after midnight for better radiant elevation
- Use peripheral vision and avoid staring at one spot to maximize sky coverage
- Record counts and fireball timings to contribute to citizen science projects
November Meteor Watching Outlook
For observers planning future campaigns, November 2017 demonstrated how multiple showers can extend activity across the month. Careful planning around lunar phases and radiant positions enhances the quality of data and enjoyment of each display.
FAQ
Reader questions
Why were the Orionids still visible in early November 2017?
The Orionid shower peaked in late October, but its debris stream remained active through early November, producing 10–15 meteors per hour as Earth continued moving through the tail of Comet Halley.
Which Taurid stream produced more fireballs in November 2017?
Both the South and Northern Taurids contributed bright fireballs, but the South Taurid stream is generally more productive in terms of larger fragments, leading to more reported fireballs around 17–20 November.
How did moonlight affect meteor observations during November 2017?
Early in the month, a waning gibbous Moon washed out fainter Orionids, while by late November the waning crescent provided darker skies that improved the visibility of Taurid fireballs after midnight.
What time of night was best for watching Taurids in November 2017?
Viewing after midnight offered higher radiant elevation for both Taurid streams, increasing the number of visible meteors and making fireballs easier to spot against darker skies.
