One Time Only: Rare Memorial Day Meteor Shower!

You will not find this meteor shower on our annual list, yet there's a chance it will be the very best display of the year! After Memorial Day fireworks are over, continue gazing toward the sky for rare meteors due to enter Earth's atmosphere that night (or the following night). The circumstances for producing a shower of this kind are rather unique, making this a brand-new, one-time only event! Read on.


In 1995, a small comet, known as 73P/Schwassmann-Wachmann 3, unexpectedly broke in to several fragments. Since that initial disruption, this comet continued to disintegrate as it orbited the Sun about every five and a half years. Dozens of bits and pieces have crumbled off of the original fragments over the last twenty years. This following clip, from 2006, demonstrates this:

May 30-31: Look For Meteors!

Astronomers world-wide have investigated the prospect of Earth’s passage through this swarm of freshly ejected material, which could lead to a meteor shower. While some think Earth will not interact with this comet’s material, others suggest our planet will have a direct interaction with the comet debris, and possibly produce an outburst of meteor activity late on the nights of Memorial Day, May 30, and May 31, 2022. (Check our Memorial Day forecast to see if the weather will be good for stargazing in your area.)

A Disclaimer for Meteor Watchers

We have never encountered this swarm before, so we can’t say for sure exactly what to expect. In the best-case scenario, a bevy of slow, bright meteors, glowing with a ruddy or orange tint, falling at the rate of hundreds of miles per hour could happen.

On the other hand, we may encounter very few comet particles—possibly none at all. There is also a chance that the meteors will be so faint that they will not be visible to the naked eye.

The occurrence of a meteor shower requires a unique set of circumstances:

1) Typically, meteor showers are caused by tiny dust or sand-grain-sized particles. In this case, the comet bits are believed to be larger: nugget-sized.

2) When the comet fractured, the material was expelled at unusually high velocities. Such material would tend to migrate ahead of the comet as it makes its way around the Sun, ultimately colliding with Earth. Unfortunately, such calculations are fraught with uncertainties.

In any event, it will be worth taking a chance at catching what could be the greatest new sky spectacle.
