Southern Taurids

 Currently active
Active from September 23rd to December 8th, 2023

The Southern Taurids are a long-lasting shower that several peaks during its activity period. The shower is active for more than

two months but rarely produces more than five shower members per hour, even at maximum activity. The Taurids (both branches) are rich in

fireballs and are often responsible for increased number of fireball reports from September through November.

Shower details - Radiant: 03:35 +14.4° - ZHR: 5 - Velocity: 17.2 miles/sec (slow - 27.7km/sec) - Parent Object: 2P/Encke

Next Peak - The Southern Taurids will next peak on the Nov 5-6, 2023 night. On this night, the moon will be 44% full.

Northern Taurids

 Currently active
Active from October 13th to December 2nd, 2023

This shower is much like the Southern Taurids, just active a bit later in the year. When the two showers are active simultaneously in late October

and early November, there is sometimes a notable increase in the fireball activity. There seems to be a seven year periodicity with these fireballs.

2008 and 2015 both produced remarkable fireball activity. 2022 may be the next opportunity.

Shower details - Radiant: 03:55 +22.8° - ZHR: 5 - Velocity: 18 miles/sec (slow - 30km/sec) - Parent Object: 2P/Encke

Next Peak - The Northern Taurids will next peak on the Nov 11-12, 2023 night. On this night, the moon will be 2% full.

Leonids

Next period of activity: November 3rd, 2023 to December 2nd, 2023

The Leonids are best known for producing meteor storms in the years of 1833, 1866, 1966, 1999, and 2001.

These outbursts of meteor activity are best seen when the parent object, comet 55P/Tempel-Tuttle, is near perihelion (closest approach to the sun).

 Yet it is not the fresh material we see from the comet, but rather debris from earlier returns that also happen to be most dense at the same time.

Unfortunately, it appears that the earth will not encounter any dense clouds of debris until 2099. Therefore, when the comet returns in 2031 and 2064, there may not be any meteor storms,

 but perhaps several good displays of Leonid activity when rates are in excess of 100 per hour. Each passing year also presents new possibilities from old debris fields. In 2022,

model calculations of Maslov (2007) and Sato (2021) show an approach of the 1733 dust trail on November 19.

Maslov gives 06h UT, Sato obtains 06h20m − 06h27m UT (λ = 236 .◦576 and λ = 236 .◦581; different ejection velocities).The possible activity level depends on

the ejection velocity (which has a negative sign in this case and observations of meteors from such trails are scarce).

Maslov adds: meteors should be bright, a ZHR of 200+ seems possible despite the uncertainties. Sato comments: ZHR may reach 50+ because the model s

uggests that the dust tends to be concentrated. An encounter with the 1600 trail (weak rate possible near November 18, 07h UT; λ = 235 .◦6) is found by Vaubaillon (2021).

 A weak rate enhancement may be visible due to the 1800 trail later on November 21, 15h UT (Maslov, 2007).The Leonids are often bright meteors with a high percentage of persistent trains.

Shower details - Radiant: 10:17 +21.6° - ZHR: 15 - Velocity: 43.5 miles/sec (swift - 70km/sec) - Parent Object: 55P/Tempel-Tuttle

Next Peak - The Leonids will next peak on the Nov 17-18, 2023 night. On this night, the moon will be 23% full.

Geminids

Next period of activity: November 19th, 2023 to December 24th, 2023

The Geminids are usually the strongest meteor shower of the year and meteor enthusiasts are certain to circle December 13 and 14 on their calendars.

 This is the one major shower that provides good activity prior to midnight as the constellation of Gemini is well placed from 22:00 onward.

The Geminids are often bright and intensely colored. Due to their medium-slow velocity, persistent trains are not usually seen.

These meteors are also seen in the southern hemisphere, but only during the middle of the night and at a reduced rate.

Shower details - Radiant: 07:24 +32.3° - ZHR: 150 - Velocity: 21 miles/sec (medium - 34km/sec) - Parent Object: 3200 Phaethon (asteroid)

Next Peak - The Geminids will next peak on the Dec 13-14, 2023 night. On this night, the moon will be 1% full.

Ursids

Next period of activity: December 13th, 2023 to December 24th, 2023

The Ursids are often neglected. The rates are much less than the Geminds, which peaks just a week before the Ursids.

Observers will normally see 5-10 Ursids per hour during the late morning hours on the date of maximum activity.

There have been occasional outbursts when rates have exceeded 25 per hour. These outbursts appear unrelated to the perihelion dates of comet 8P/Tuttle.

This shower is strictly a northern hemisphere event as the radiant fails to clear the horizon or does so simultaneously with the start of morning twilight as seen from the southern tropics.

Shower details - Radiant: 14:36 +75.3° - ZHR: 10 - Velocity: 20.5 miles/sec (medium - 33km/sec) - Parent Object: 8P/Tuttle

Next Peak - The Ursids will next peak on the Dec 21-22, 2023 night. On this night, the moon will be 74% full.

Quadrantids

Next period of activity: December 26th, 2023 to January 16th, 2024

The Quadrantids have the potential to be the strongest shower of the year but usually fall short due to the short length of maximum activity (6 hours) and the poor weather experienced during early January.

 The average hourly rates one can expect under dark skies is 25. These meteors usually lack persistent trains but often produce bright fireballs. Due to the high northerly declination (celestial latitude)

these meteors are not well seen from the southern hemisphere.

Shower details - Radiant: 15:20 +49.7° - ZHR: 120 - Velocity: 25 miles/sec (medium - 40.2km/sec) - Parent Object: 2003 EH (Asteroid)

Next Peak - The Quadrantids will next peak on the Jan 3-4, 2024 night. On this night, the moon will be 51% full.

Lyrids

Next period of activity: April 15th, 2024 to April 29th, 2024

The Lyrids are a medium strength shower that usually produces good rates for three nights centered on the maximum.

 These meteors also usually lack persistent trains but can produce fireballs. These meteors are best seen from the northern hemisphere where the radiant is high in the sky at dawn.

 Activity from this shower can be seen from the southern hemisphere, but at a lower rate.

Shower details - Radiant: 18:10 +33.3° - ZHR: 18 - Velocity: 29 miles/sec (medium - 46.8km/sec) - Parent Object: C/1861 G1 (Thatcher)

Next Peak - The Lyrids will next peak on the Apr 22-23, 2024 night. On this night, the moon will be 99% full.

eta Aquariids

Next period of activity: April 15th, 2024 to May 27th, 2024

The Eta Aquariids are a strong shower when viewed from the southern tropics. From the equator northward, they usually only produce medium rates of 10-30 per hour just before dawn.

Activity is good for a week centered the night of maximum activity. These are swift meteors that produce a high percentage of persistent trains, but few fireballs.

Shower details - Radiant: 22:30 -1° - ZHR: 50 - Velocity: 40.7 miles/sec (swift - 65.5km/sec) - Parent Object: 1P/Halley

Next Peak - The eta Aquariids will next peak on the May 5-6, 2024 night. On this night, the moon will be 6% full.

Southern delta Aquariids

Next period of activity: July 18th, 2024 to August 21st, 2024

The Delta Aquariids are another strong shower best seen from the southern tropics. North of the equator the radiant is located lower in the southern sky

and therefore rates are less than seen from further south. These meteors produce good rates for a week centered on the night of maximum.

These are usually faint meteors that lack both persistent trains and fireballs.

Shower details - Radiant: 22:42 -16.3° - ZHR: 25 - Velocity: 25 miles/sec (medium - 40km/sec) - Parent Object: 96P/Machholz?

Next Peak - The Southern delta Aquariids will next peak on the Jul 30-31, 2024 night. On this night, the moon will be 20% full.

alpha Capricornids

Next period of activity: July 7th, 2024 to August 15th, 2024

The Alpha Capricornids are active from July 7 through August 15 with a "plateau-like" maximum centered on July 31st.

This shower is not very strong and rarely produces in excess of five shower members per hour. What is notable about this shower is the number of bright fireballs produced during its activity period.

This shower is seen equally well on either side of the equator.

Shower details - Radiant: 20:26 -9.12° - ZHR: 5 - Velocity: 14 miles/sec (slow - 22km/sec) - Parent Object: 169P/NEAT

Next Peak - The alpha Capricornids will next peak on the Jul 30-31, 2024 night. On this night, the moon will be 20% full.

Perseids

Next period of activity: July 14th, 2024 to September 1st, 2024

The Perseids are the most popular meteor shower as they peak on warm August nights as seen from the northern hemisphere.

The Perseids are active from July 14 to September 1. They reach a strong maximum on August 12 or 13, depending on the year.

Normal rates seen from rural locations range from 50-75 shower members per hour at maximum. The Perseids are particles released from comet 109P/Swift-Tuttle

during its numerous returns to the inner solar system. They are called Perseids since the radiant (the area of the sky where the meteors seem to originate) is located near t

he prominent constellation of Perseus the hero when at maximum activity.

Shower details - Radiant: 03:13 +58° - ZHR: 100 - Velocity: 37 miles/sec (swift - 59km/sec) - Parent Object: 109P/Swift-Tuttle

Next Peak - The Perseids will next peak on the Aug 12-13, 2024 night. On this night, the moon will be 54% full.
