Taurid meteors: Will there be a swarm this year?

You can see this meteor is radiating from the constellation Taurus the Bull. See that V-shaped pattern to the right and above Orion? That’s the Hyades star cluster, which forms the Bull’s Face. Eliot Herman in Tucson caught this Taurid meteor in 2015. The bright object was the moon! Thanks, Eliot. 2015 was the last good year for the Taurid meteors. Will there be a swarm this year?

What are the Taurid meteors?

The South and North Taurid meteor showers are active every year throughout the months of October and November. They’re billed as a major annual meteor shower, but observers rarely see more than five meteors per hour. Astronomers studying the Taurids found that Earth encounters a concentration of larger-than-normal debris at intervals of three or seven years. Close conjunctions with the planet Jupiter cause this concentration. Interestingly, only the southern branch has this concentration of debris. Fireballs, or meteors that are larger and brighter than anything in the sky except the sun and moon, probably come from these larger particles.

The South Taurids run from about September 10 until November 20, peaking around November 4/5. The North Taurids overlap them, running from around October 20 to December 10, peaking around November 12/13.

Will we see a swarm of Taurid meteors in 2022?

Taurid fireballs are often colorful and display fragmentation as they streak slowly through the sky. During a normal display, only 1% of all Taurid meteors are fireballs. In exceptional years, when the Earth passes through a concentrated field of debris, the percentage can be as high as 7%. So visual observers and astrophotographers may see several fireballs each night instead of the normal rate of one every 20 hours. The last time the Earth encountered a concentration or swarm of Taurid meteors was in 2015. That year, rates for the South Taurids reached 10 per hour with numerous fireballs, such as the one pictured above.

This year we have another opportunity to witness enhanced rates during a two-week period centered on the peak date of November 5th. Unfortunately, a full moon occurs on November 8, so only a few hours of dark skies are available on the 5th. The moon will wash out most meteors on the days after the predicted peak. However, fireballs are bright enough to shine through the moonlight. The best observing time is before the full moon arrives on November 8. However, if you’re out on the morning of November 8 watching the total lunar eclipse, maybe you’ll get lucky and spot some Taurid meteors as well.

The radiant of the Taurid meteor shower

The radiant of the South Taurids is located in western Taurus, south of the the famous Pleiades star cluster. Due to the motion of the Earth around the sun, the radiant will drift eastward just under one degree each night and slightly northward. Therefore, if you are watching for Taurids in October, the radiant will be in the constellation Aries. Viewing after November 5, the radiant is slowly approaching the familiar V-shaped asterism of the Hyades in Taurus.

As seen from the Northern Hemisphere, the Taurid radiant lies above the horizon all night long. It’s highest near 2:00 a.m. local time. If observing during the evening hours, look eastward. Those viewing after 2 a.m. should face west. If the moon is in the sky, keep it out of your field of view to avoid ruining your night vision. The Taurid meteors are visible from most of the Southern Hemisphere but in lower numbers, because the radiant appears lower in the sky from places south of the equator.

The Taurid meteors consist of 2 streams, the South Taurid meteors and North Taurid meteors. Both streams appear to originate from near Taurus the Bull. You might see South or North Taurids throughout October and into November. Chart via Chelynne Campion/ EarthSky.

Observers can submit number of meteors sighted

Serious observers are invited to count the number of meteors observed and submit them to the International Meteor Organization (IMO). This option is for registered members, but it’s free to those who just wish to contribute data. It creates an observing log you keep and add to after each meteor shower session. To produce scientifically useful data, please refer to information on visual observations. Plus, you’ll want to determine your viewing conditions.

You should view for at least one hour to get a true picture of the overall activity. Also, check here for more tips on viewing meteor showers. Meteors rarely appear at regular intervals but often appear in spurts with gaps of five to 10 minutes with no activity. We advise observers to use a comfortable lounge chair with a pillow and blanket. Being cold is no fun while out under the stars!

When are future swarms predicted?

The next predicted Taurid swarm is in 2025 and will most likely be weaker than 2022, especially because a full moon occurs on the same night as maximum peak activity. Beyond that, 2032 appears to be an exceptional year, as the moon will be new and Earth will pass very close to the center of the swarm. Mark your calendar now!

Bottom line: Take advantage of this opportunity to witness a possible increase in fireball activity of Taurid meteors by viewing the sky from October 29 through November 7, 2022.
