Delta Acuáridas is an annual meteor rain that marks the beginning of summer stars. This phenomenon occurs in the remains of the 96p/Macholz comet, whose fragments fall into the atmosphere of the Earth, generating a bright step that characterizes these rains. Although they are not as well known as Persias, Delta Acuáridas offers a constant and long show for several weeks, and activity can reach 25 meteors per hour in the maximum.
The activity of this rain begins in mid -July and extends until the end of August, which is an early clock on August 1, 2025 at a time of greater intensity. The lunar phase in this date will be favorable, which will allow dark conditions to observe the phenomenon. During this period, radiating, the point from where meteors appear, will be located in the constellation Aquarius, visible from the most part of the planet.
This event is an accessible opportunity for those who want to observe the night sky without the need for specialized equipment. Nevertheless, the quality of the observation largely depends on the weather conditions and the location of the observer is crucial to avoid areas with high light pollution in order to maximize visibility.
When to observe the rain of the stars
The Acucharides Delta is a meteor rain, which occurs every year from July 12 to August 23. In 2025, the National Astronomical Observatory indicates that the maximum activity will take place around July 31, so the nights on July 30 and 31, as well as the early hours of August 1, will be the most suitable for their observation.
According to the lunar calendar in July 2025, the moon will be close to the growing room on these dates, which implies that the conditions of observation will improve after midnight. At that time, shining, which is the point of the sky, where meteors come from, will rise, contributing to the better visibility of this phenomenon.
How to watch the Acucharids delta
To optimize observation experience, it is recommended to move to places away from the city areas, where the pollution of the light is minimal, and the view of the night sky is clear. The use of optical instruments, such as prismatic or telescopes, is not recommended, since they limit the field of view necessary to detect meteors.
The astronomical observatory involves the direction of the view of the darkest parts of the sky, preferably in the opposite direction to the position of the moon, when it is visible. It is recommended to take convenient posture, such as lying down, and allow the look to adapt to the darkness for at least 20 minutes to improve perception.
The best time to observe the rain of stars is after the moon hides either after sunset, in the early hours of the morning, when the sky is darker and light pollution is minimized.
Where to see the rain of the stars
In the latitudes like the Iberian peninsulas, the radiant radiation of the Akuarida delta begins to rise on the horizon from midnight, which increases the chances of observing meteors. Although this phenomenon is more noticeable in the southern hemisphere, where the radiation is higher, it is also perceived from the northern hemisphere, including Spain. Nevertheless, the quality of surveillance improves significantly if it avoids proximity to city centers with high light pollution.
Any place with a clear sky and without artificial light is suitable for observation. It is recommended to lie down, let the eyes approach the darkness and do not look directly to the sources of the light, whether it be the moon or artificial lighting.
