The Delta Aquarid meteor shower has already begun. They may peak around July 27-30 - next weekend - but the numbers are actually fairly steady throughout the month. People in tropical latitudes in the northern hemisphere and people in the southern hemisphere will see more meteors than elsewhere. However they can be seen from around the world. They seem to radiate from the constellation Aquarius.

The maximum hourly rate can reach 15-20 meteors in a dark sky, but most people won't see that. The best time to see them is about and hour or two before dawn because that's when you get the best view of that part of the sky.

By early August a gibbous - then full - Moon will wipe out the view of the fainter meteors, so try to get a good look when the Moon is less full and setting by midnight.

What's the difference between a meteor, a meteorite and a meteoroid? Is one of them the same as a shooting star? And what about asteroids and planetoids - which one is a minor planet? If any of these terms have puzzled you, here is a guide to help you out.

The radiant is the part of the sky where the meteors seem to originate. (They don't actually.) If you know the general direction of the radiant you’ll be able to tell shower members from random meteors. If you can trace the path of a meteor backward toward Aquarius, chances are it’s an Aquarid. There are actually two meteor showers in Aquarius active this time of year – the northern and southern Delta Aquarids. The northern version sprinkles fewer meteors and peaks in mid-August.

Here's a diagram showing where Delta Aquarii is. You don't have to look up at Aquarius to see meteors, as in a meteor shower you can see them anywhere in the sky.

The second summer shower is the big one, the Perseids.

Meteor Shower - the Perseids

When August comes around, the best sky show of the year is also on its way. The Perseids are an annual meteor shower. What's it all about and how can you see it?

Here's some helpful tips on meteor watching from Sky & Telescope. This includes instructions for serious observers, but some of it applies to anyone wanting to get some enjoyment out of seeing "shooting stars".

You're more likely to see them after midnight, but that doesn't mean you won't see anything earlier.

1. Find the darkest place you can with a clear view of the sky.
2. Be sure to take all the safety precautions you normally would when out in the dark.
3. Take reclining lawn chairs (or camping mattresses for those who are fit), so you can lie back and watch the sky without getting a stiff neck.
4. Insect repellent if there are mosquitoes around.
5. Something warm in case it gets chilly and perhaps a hot drink.
6. You're most likely to see meteors - and anything else in the sky! - if you give your eyes time to adapt to the dark, at least 10-15 minutes. No lights on during that time unless it has a red filter. (So keep the phone off!)

You not only don't need a telescope or binoculars, you don't want them. Optical aids will restrict your view. Just lean back and enjoy the sky.

Here's the EarthSky meteor shower guide for 2017. It has links to the dates of the showers and helpful hints on observing.

This week – during the dark hours before dawn on or near July 28, 2017 – the Delta Aquarid meteor shower should reach its peak. The Delta Aquarids are a long, rambling shower, which will stretch out for weeks beyond the peak. The peak itself isn’t very definite, but – if you want to watch around the peak – now is the time. With no moon to ruin the show in the best hours to watch – before dawn as seen from around the world – this week is a good time to watch for these rather faint meteors, which might number about 10 to 15 meteors per hour in a dark sky.

The most favorable viewing window begins about 2 a.m. Daylight Saving Time, no matter where you are on Earth … through the onset of morning dawn. Although this shower is visible from both the Northern and Southern Hemispheres, it tends to favor the more southerly latitudes. North of the equator, it’s better seen in the tropical and subtropical regions rather than farther north. This shower will combine with the more-famous Perseid meteor shower, now rising to its peak, but whose peak in 2017 will be drowned in bright moonlight.

That’s why now is the time to watch meteors.

The Perseids are already underway and the number of meteors is gradually increasing. Here's a handy summary.

Perseid Meteors over Turkey This is a composite image taken during last year's Perseids. There are so many meteors in the picture, you can see where the radiant is on the far left in the constellation Perseus.

The tail-end of the Perseids will still be going during the total solar eclipse on August 21, creating a rare opportunity for some lucky astrophotographers to image a Perseid meteor during the day.

NASA reminds us:
Quote:
Sky watchers will be in for a treat this week, when the annual Perseid meteor shower reaches its peak! If you've never seen a meteor before, this is the ideal opportunity. Maximum activity is expected between 11 and 13 August. Keep away from bright lights, let your eyes adapt to the darkness, and lie back and stare at the sky!

Here's a diagram to show the Perseid radiant, but remember you might see meteors all around the sky.
