Scientists Alert Skywatchers To Arietids: Most Active Daytime Meteor Shower Peaks June 7
Daytime meteor shower in June 2025 … the Arietids
The majority of meteor showers are simple to see. Simply locate a dark sky and raise your gaze! However, what about meteor showers that occur during the day, after the sun has risen? Some claim that the Arietids are the most active meteor shower during the day. They are expected to **peak** on the mornings of June 7 in 2025. In the dark hour before dawn that morning, you might see some Arietids.
When to watch: From May 29 to June 17, Arietids will be available. The mornings around June 7 are expected to reach their **peak. During the dark hour prior to dawn, search for them in the direction of the rising sun.
Nearest lunar phase: On June 3, at 3:41 UTC, the moon entered its first quarter phase.
Radiant: The constellation Aries the Ram has the shower’s radiant point, which is the location in the sky from which the meteors seem to radiate. This constellation is located in the east before sunrise.
The shower lasted from May 29 to June 17.
Peak predicted meteor activity: This is challenging for meteor showers during the day because you won’t be able to see them when the sun rises. The hourly rate of the Arietids, however, is zenithal! A rate of 60 meteors per hour, and maybe as much as 200 meteors per hour, has been reported by meteor counts using radar and radio echoes.
Note: Some claim that the Arietids are the most active meteor shower during the day.

More about a shower’s radiant point
Only 30 degrees separate the sun from the radiant point of the Arietids shower, which is the location in the sky from which the meteors seem to radiate. The shower’s elongation is this 30-degree angle, which is the angle between the sun and the meteor radiant as viewed from Earth.
How to observe the Arietids
Therefore, even though the majority of Arietid meteors fly during the day, you could still see one in the final dark hour before sunrise, which could happen at any moment throughout the first and second weeks of June.
The goal is to catch them in the small window just before the visible dawn breaks, but after the radiant has risen or is about to rise. The radiant appears just prior to the start of the darkest twilight stage, known as astronomical twilight, which is the time when the sun’s centre is between 12 and 18 degrees below the horizon. Astronomical dusk is presumably when you won’t even detect any light in the sky.
Look to the east and keep an eye out for meteors departing from the radiant. From the radiant, the meteors will be travelling in all directions. As a result, very few will ever cross your horizon. In your eastern predawn sky, however, a few meteors will ascend.
How many meteors will you see?
The number of meteors you will see in an hour when the radiant is directly overhead and you can see stars as faint as magnitude 6.5 is known as the shower’s zenithal hourly rate.
We have a few issues with meteor showers during the day. It is daytime when the radiant from a meteor shower is overhead. Therefore, stars with a magnitude of 6.5 are invisible. The radiant of a meteor shower during the day lies below your horizon when it gets dark and you may see faint stars.
Therefore, the conditions for observing the Arietids are never optimum. But their hourly fee is fantastic! A rate of 60 meteors per hour, and maybe as much as 200 meteors per hour, has been reported by meteor counts using radar and radio echoes.
On the morning of June 7th, or on the mornings surrounding that date, how many will you see? Experts frequently disagree on meteor shower maxima. Who knows, though? Seeing any meteors from this (mainly) midday shower would also be entertaining.
The NASA Meteor Shower Portal allows you to monitor the activity of meteor showers during the day as well as those that are not visible to the naked eye. To view different parts of the sky, you can move the sky globe. White dots show intermittent (random) activity, while coloured dots show shower meteors. There won’t be much activity in that region of the sky because the sun’s position is indicated by the enormous orange disc.
Arietids history and parent comet
The history of the Arietids is intriguing. They were originally observed in 1947 by astronomers using the Jodrell Bank Radio Telescope in England. This study covers this meteor shower during the day, along with three others. Radar echoes were used to make the finding, and in certain cases, pictures were used to corroborate it.
The parent comet of the Arietids was unknown for many years. Then, in May 1986, Don Machholz made the discovery of 96P/Machholz, a comet. This meteor shower may have a direct connection to this comet, or the Machholz Complex may be the shower’s source. Two comet groups, eight meteor showers, and at least one asteroid are all connected to Comet 96P/Machholz to form the Machholz Complex.
