Tonight – November 4, 2015 – should be a peak night for the annual South Taurid meteor shower. Tomorrow night (November 5) should be good as well. Though a modest shower, with a predicted peak rate of about 7 meteors per hour, the Taurids can surprise you with a flamboyant fireball or two! The meteors will be flying from late night until dawn.
The moon is now in a waning crescent phase. It’s up in the peak predawn hours, but shouldn’t interfere too much with viewing any fireballs that happen to be whizzing by. Seeing a Taurid fireball – even if it’s just one – counts as a big thrill.
And, by the way, a fireball is just another word for a particularly bright meteor.
The other Taurid shower – the North Taurids – should add a few more meteors to the mix from late night until dawn, on the nights of November 5 and 6. The forecast calls for the North Taurid shower to be raining down the most meteors on the night of November 11, 2015. The moon will be new about then, offering pitch-black skies.
As a general rule, the Taurid showers do not exhibit strong peaks. The two Taurid showers tend to overlap and to plateau in activity during the first few weeks in November. On any given night, these rather slow-moving meteors produce the greatest numbers in the few hours after midnight, perhaps as many as 7-10 meteors per hour on a moonless night. However, the Taurids may have a 7-year cycle of bright fireballs, and 2015 appears to be the peak! Read more about that, and see more fireball photos, here.
If you trace the South Taurid meteors backwards, they all appear to radiate from the constellation Taurus the Bull. As always, you don’t have to identify a meteor shower’s radiant point to watch the meteor shower. Just lie back comfortably and look up, in the hours between midnight and dawn.
Now … let’s talk more about meteor shower radiant points. Take a look at the two photos below. Both have about the same star background (the second is slightly later at night than the first). Eliot Herman captured both photos within about a week of each other – the first on the morning of October 23, 2015, and the second on the morning of November 1, 2015. What’s different about these two photos? Well, the second one has a bright moon, but that’s not what we’re asking you to notice. When you look at these two photos, you’re seeing meteors streaking from two different radiant points. So you know these are meteors in two different showers.
In fact, the radiant points for both early November meteor showers – the South Taurids and North Taurids – are in the constellation Taurus. As can be expected, the radiant point for the South Taurids is found in southern Taurus, while that of the North Taurids is found in northern Taurus.
Taurus the Bull – the Taurid showers’ radiant point – climbs upward during the evening hours and reaches its highest point in the sky after midnight. The higher that Taurus appears in your sky, the more Taurid meteors that are likely to fly.
Just be aware … you don’t need to find Taurus to watch the Taurid shower, for these meteors streak all over the sky.
Bottom line: The annual South Taurid meteor shower peaks in early November, 2015. Because the Taurids are known for putting out bright fireballs, you might even see one or two lighting up the starry sky.
