Delta Aquarid Meteor Shower

Delta Aquarid Meteor Shower

At the end of this week, look up! The Delta Aquarids are coming to a night sky near you. In 2019, peak activity occurs in the evening of 28-29 July.

The Delta Aquarid meteor shower is an annual shower that can be seen from 12 July until 23 August. This year the peak will fall on the night of Sunday 28 July and the morning of Monday 29 July. The Delta Aquarids are a small to medium shower, reaching a peak rate of around 20 meteors per hour.

The good news is that the waning crescent Moon won’t rise until after 2am on Monday 29 July, leaving a dark night sky for good meteor spotting.

Most meteor showers are caused by the debris left behind from comets that melt as they orbit the Sun. Each year, the Earth passes through some of these debris paths and small dust grains hit Earth’s atmosphere at enormously high speeds. They heat up in the atmosphere and disintegrate in flashes of light that we call meteors.

The comet that created the debris for the Delta Aquarids is not quite known, but it may be from a comet called 96P Machholz, which only takes about five years to orbit the Sun.

How to Watch

The radiant point of the Delta Aquarids sits in the constellation of Aquarius, hence the name. If you were to trace the shooting stars back to their radiant point you may notice something quite interesting. The Delta Aquarids actually have two radiant points. The shower is actually a combination of two showers, the Northern and the Southern Delta Aquarids. The southern shower starts earlier and is a little more active, while the northern portion covers the end of the timescale and generally has a lower rate.

While the meteors appear to originate from Aquarius, they are best seen 30 degrees away from origin, so be sure to keep careful watch across the whole sky.

To view the Delta Aquarids from the UK, head outside anytime after midnight on the night of the 28-29 July.

Look up, keep an eye on the whole sky, and find a location as far from city lights as you can!

If it’s cloudy on the 28th, you can always try your luck on a nearby day. The Delta Aquarids are active from 12 July – 23 August, and will overlap with the biggest meteor shower of the year – the Perseids!
