Next up: Late July and early August, 2013, the Delta Aquarids
Like the Eta Aquarids in May, the Delta Aquarid meteor shower in July favors the Southern Hemisphere and tropical latitudes in the Northern Hemisphere. The meteors appear to radiate from near the star Skat or Delta in the constellation Aquarius the Water Bearer. The maximum hourly rate can reach 15-20 meteors in a dark sky. The nominal peak is around July 29-30, but, unlike many meteor showers, the Delta Aquarids lack a very definite peak. Instead, these medium-speed meteors ramble along fairly steadily throughout late July and early August. An hour or two before dawn usually presents the most favorable view of the Delta Aquarids, assuming the moon is out of the way. In late July, 2013, the rather faint Delta Aquarid meteors will be at least partially drowned in the light of a bright last quarter moon on July 29. Try watching in early August, when the Perseid meteor shower is building to its peak and the light of the waning crescent moon is less obtrusive. The absence of the moon in 2014 will make next year a favorable one for watching the Delta Aquarids.

January 3, 2013 before dawn, the Quadrantids
Although the Quadrantids can produce over 100 meteors per hour, the sharp peak of this shower tends to last only a few hours, and doesn’t always come at an opportune time. In other words, you have to be in the right spot on Earth to view this meteor shower in all its splendor. The radiant point is in the part of the sky that used to be considered the constellation Quadrans Muralis the Mural Quadrant. You’ll find this radiant near the famous Big Dipper asterism (chart here), in the north-northeastern sky after midnight and highest up before dawn. Because the radiant is fairly far to the north on the sky’s dome, meteor numbers will be greater in the Northern Hemisphere. In 2013, watch in the wee hours – after midnight and before dawn – on January 3. Unfortunately, the bright waning gibbous moon lights up the early morning hours before dawn, the best time of night to watch for these meteors. If this year’s forecast proves correct, western North America and the islands of the North Pacific Ocean might enjoy the most favorable location on the morning of January 3. From eastern and northern Asia, try after midnight and before dawn on January 4 as well, in case the peak comes later than expected. Remember, meteor showers are notorious for defying predictions. This shower is worth a try at northerly latitudes all around the globe. .
April 22, 2013 before dawn, the Lyrids
The Lyrid meteor shower – April’s shooting stars – lasts from about April 16 to 25. Lyrid meteors tend to be bright and often leave trails. About 10-20 meteors per hour can be expected at their peak. Plus, the Lyrids are known for uncommon surges that can sometimes bring the rate up to 100 per hour. Those rare outbursts are not easy to predict, but they’re one of the reasons the tantalizing Lyrids are worth checking out around their peak morning. The radiant for this shower is near the bright star Vega in the constellation Lyra (chart here), which rises in the northeast at about 10 p.m. on April evenings. In 2013, the peak morning is April 22, but you might also see meteors before and after that date. There’s a bright waxing gibbous moon in the sky during the Lyrid peak. The greatest number of Lyrid meteors commonly fall in the dark hours just before dawn, so trying watching this meteor shower after moonset – in other words, shortly before dawn on April 22.
May 4-6, 2013 before dawn, the Eta Aquarids
This meteor shower has a relatively broad maximum – meaning you watch watch it for several days around the predicted peak. The radiant is near the star Eta in the constellation Aquarius the Water Bearer (click here for chart). The radiant comes over the eastern horizon at about 4 a.m. local time; that is the time at all locations across the globe. For that reason, the hour or two before dawn tends to offer the most Eta Aquarid meteors, no matter where you are on Earth. At northerly latitudes – like those in the northern U.S. and Canada, or northern Europe, for example – the meteor numbers are typically lower for this shower. In the southern half of the U.S., 10 to 20 meteors per hour might be visible in a dark sky. Farther south – for example, at latitudes in the Southern Hemisphere – the meteor numbers may increase dramatically, with perhaps two to three times more Eta Aquarid meteors streaking the southern skies. For the most part, the Eta Aquarids is a predawn shower. In 2013, the waning crescent moon should not intrude too greatly on the Eta Aquarid shower. The most meteors will probably rain down on May 5, in the dark hours before dawn. But watch on May 4 and 6 as well! The broad peak to this shower means that some meteors may fly in the dark hour before dawn for a few days before and after the predicted optimal date.
August 10-13, 2013 before dawn, the Perseids
The Perseid meteor shower is perhaps the most beloved meteor shower of the year for the Northern Hemisphere. The shower builds gradually to a peak, often produces 50 to 100 meteors per hour in a dark sky at the peak, and, for us in the Northern Hemisphere, this shower comes when the weather is warm. The Perseids tend to strengthen in number as late night deepens into midnight, and typically produce the most meteors in the wee hours before dawn. They radiate from a point in the constellation Perseus the Hero, but, as with all meteor shower radiant points, you don’t need to know Perseus to watch the shower; instead, the meteors appear in all parts of the sky. They are typically fast and bright meteors. They frequently leave persistent trains. Every year, you can look for the Perseids around August 10-13. They combine with the Delta Aquarid shower (above) to produce the year’s most dazzling display of shooting stars. In 2013, the Perseid meteors will streak across the short summer nights – August 10-13 – from late night until dawn, with little to no interference from the waxing crescent moon. Plus the moon will be near the planet Saturn in the evening hours, giving a colorful prelude to late-night Perseid show. Best mornings to look: August 11, 12 and 13.
October 7-8, 2013, the Draconids
The radiant point for the Draconid meteor shower almost coincides with the head of the constellation Draco the Dragon in the northern sky. That’s why the Draconids are best viewed from the Northern Hemisphere. The Draconid shower is a real oddity, in that the radiant point stands highest in the sky as darkness falls. That means that, unlike many meteor showers, the Draconids are more likely to fly in the evening hours than in the morning hours after midnight. This shower is usually a sleeper, producing only a handful of languid meteors per hour in most years. But watch out if the Dragon awakes! In rare instances, fiery Draco has been known to spew forth many hundreds of meteors in a single hour. In 2013, the thin waxing crescent moon won’t cast enough moonlight to interfere with the Draconids. Try watching at nightfall and early evening on October 7 and 8.
October 21, 2013 before dawn, the Orionids
On a dark, moonless night, the Orionids exhibit a maximum of about 10 to 20 meteors per hour. These fast-moving meteors occasionally leave persistent trains. They sometimes produce bright fireballs, so you might see a few Orionids even in moon-drenched skies. If you trace these meteors backward, they seem to come from the Club of the famous constellation Orion the Hunter. You might know Orion’s bright, ruddy star Betelgeuse. The radiant is north of Betelgeuse. The Orionids have a broad and irregular peak that isn’t easy to predict. More meteors tend to fly after midnight, and the Orionids are typically at their best in the wee hours before dawn. This year, 2013, is not optimal for watching the Orionid meteor shower because a bright waning gibbous moon will be in the sky during the peak hours between midnight and dawn. But you might see some meteors even in bright moonlight. The best viewing for the Orionids in 2013 will probably be before dawn on October 21. Try the days before and after that, too, sticking to the midnight-to-dawn hours. You’ll be watching for those brightest Orionids that can overcome the moon’s glare..
Late night November 4 until dawn November 5, 2013, the South Taurids
The meteoroid streams that feed the South (and North) Taurids are very spread out and diffuse. That means the Taurids are extremely long-lasting (September 25 to November 25) but usually don’t offer more than about 7 meteors per hour. That is true even on the South Taurids’ expected peak night. The Taurids are, however, well known for having a high percentage of fireballs, or exceptionally bright meteors. Plus, the other Taurid shower – the North Taurids – always adds a few more meteors to the mix during the South Taurids’ peak night. In 2013, the thin waxing crescent moon will set at early evening on November 4, leaving dark skies for the peak night of the South Taurid meteor shower. The South Taurids should produce their greatest number of meteors in the wee hours – between midnight and dawn – on November 5. Remember, even a single bright meteor can make your night!
Late night November 11 until dawn November 12, 2013, the North Taurids
Like the South Taurids, the North Taurids meteor shower is long-lasting (October 12 – December 2) but modest, and the peak number is forecast at about 7 meteors per hour. The North and South Taurids combine, however, to provide a nice sprinkling of meteors throughout October and November. Typically, you see the maximum numbers at around midnight, when Taurus the Bull is highest in the sky. Taurid meteors tend to be slow-moving, but sometimes very bright. In 2013, a bright waxing gibbous moon will bleach out all but the brighter meteors during the evening and wee morning hours. But the moon will set after midnight, providing lots of predawn darkness for watching the North Taurids on the morning of November 12.
Late night November 16 until dawn November 17, 2013, the Leonids
Radiating from the constellation Leo the Lion, the famous Leonid meteor shower has produced some of the greatest meteor storms in history – at least one in living memory, 1966 – with rates as high as thousands of meteors per minute during a span of 15 minutes on the morning of November 17, 1966. Indeed, on that beautiful night in 1966, the meteors did, briefly, fall like rain. Some who witnessed the 1966 Leonid meteor storm said they felt as if they needed to grip the ground, so strong was the impression of Earth plowing along through space, fording the meteoroid stream. The meteors, after all, were all streaming from a single point in the sky – the radiant point – in this case in the constellation Leo the Lion. Leonid meteor storms sometimes recur in cycles of 33 to 34 years, but the Leonids around the turn of the century – while wonderful for many observers – did not match the shower of 1966. And, in most years, the Lion whimpers rather than roars, producing a maximum of perhaps 10-15 meteors per hour on a dark night. Like many meteor showers, the Leonids ordinarily pick up steam after midnight and display the greatest meteor numbers just before dawn. In 2013, the full moon will interfere with the Leonid meteor shower. A full moon, after all, shines all night long, leaving no dark time for viewing the meteor shower. Still, the peak mornings will be November 17 or 18. Maybe you’ll see some meteors in the bright moonlight.
December 13-14, 2013, mid-evening until dawn, Geminids
Radiating from near the bright stars Castor and Pollux in the constellation Gemini the Twins, the Geminid meteor shower is one of the finest meteors showers visible in either the Northern or the Southern Hemisphere. The meteors are plentiful, rivaling the August Perseids, with perhaps 50 to 100 meteors per hour visible at the peak. Plus Geminid meteors are often bright, so, if there’s a bright moon, many meteors may be able to overcome the harsh moonlight. These meteors are often as good in the evening as in the hours between midnight and dawn. In 2013, a bright waxing gibbous moon will interfere with the Geminids throughout most of the peak night. Your best bet is to watch on the mornings of December 13 and 14, from moonset until dawn.

A word about moonlight. In 2013, moonlight will not pose much of a problem for the May Eta Aquarids, the August Perseids, October Draconids and November South Taurids. There’s moon-free viewing time for the January Quadrantids, April Lyrids and July Delta Aquarids. The full moon gets in the way of the November Leonids. Our almanac page provides links for access to the moonrise and moonset times in your sky.
Most important: a dark sky. Here’s the first thing – the main thing – you need to know to become as proficient as the experts at watching meteors. That is, to watch meteors, you need a dark sky. It’s possible to catch a meteor or two or even more from the suburbs. But, to experience a true meteor shower – where you might see several meteor each minute – avoid city lights.
Know your dates and times. You also need to be looking on the right date, at the right time of night. Meteor showers occur over a range of dates, because they stem from Earth’s own movement through space. As we orbit the sun, we cross “meteor streams.” These streams of icy particles in space come from comets moving in orbit around the sun. Comets are fragile icy bodies that litter their orbits with debris. When this cometary debris enters our atmosphere, it vaporizes due to friction with the air. If moonlight or city lights don’t obscure the view, we on Earth see the falling, vaporizing particles as meteors. The Lyrids take place between about April 16 and 25. The peak morning in 2013 should be April 22, but you might catch Lyrid meteors on the nights around that date as well.
Where to go to watch a meteor shower. You can comfortably watch meteors from many places, assuming you have a dark sky: a rural back yard or deck, the hood of your car, the side of a road. State parks and national parks are good bets, but be sure they have a wide open viewing area, like a field; you don’t want to be stuck in the midst of a forest on meteor night. An EarthSky friend and veteran meteor-watcher and astrophotographer Sergio Garcia Rill also offers this specific advice:
… you might want to give it a try but don’t know where to go. Well, in planning my night photoshoots I use a variety of apps and web pages to know how dark the sky is in a certain location, the weather forecast, and how the night sky will look. Here’s the link to Dark Sky Finder. It’s a website that shows the light pollution in and around cities in North America which has been fundamental for finding dark sites to setup shots. Dark Sky finder also has an app for iPhone and iPad which as of this writting is only 99 cents so you might want to look into that as well. For people not in North America, the Blue Marble Navigator might be able to help to see how bright are the lights near you.
The other tool I can suggest is the Clear Sky Chart. I’ve learned the hard way that, now matter how perfectly dark the sky is at your location, it won’t matter if there’s a layer of clouds between you an the stars. This page is a little hard to read, but it shows a time chart, with each column being an hour, and each row being one of the conditions like cloud coverage and darkness. Alternatively, you could try to see the regular weather forecast at the weather channel or your favorite weather app.
What to bring with you. You don’t need special equipment to watch a meteor shower. If you want to bring along equipment to make yourself more comfortable, consider a blanket or reclining lawn chair, a thermos with a hot drink, binoculars for gazing at the stars. Be sure to dress warmly enough, even in spring or summer, especially in the hours before dawn. Binoculars are fun to have, too. You won’t need them for watching the meteor shower, but, especially if you have a dark sky, you might not be able to resist pointing them at the starry sky.
Are the predictions reliable? Although astronomers have tried to publish exact predictions in recent years, meteor showers remain notoriously unpredictable. Your best bet is to go outside at the times we suggest, and plan to spend at least an hour, if not a whole night, reclining comfortably while looking up at the sky. Also remember that meteor showers typically don’t just happen on one night. They span a range of dates. So the morning before or after a shower’s peak might be good, too.
Peak dates are derived from data published in the Observer’s Handbook by the Royal Astronomical Society of Canada and Guy Ottewell’s Astronomical Calendar.
Bottom line: The next shower for 2013 is the Eta Aquarid shower, peaking around the morning of May 5. The mornings before and after that might be good, too. Have fun!
