Meteor Activity Outlook for 2-8 August 2025

Meteor activity kicks into high gear in August as seen from the northern hemisphere. The main reason for all this activity is the Perseid shower that peaks on August 13th. This shower is active most of the month and remains above the level of the sporadic background for a week centered on August 13th. The sporadic activity is also near maximum as seen from the northern hemisphere and is now more than double the rates from just three months ago. As seen from the southern hemisphere, meteor rates are still decent but falling rapidly. The sporadic rates continue their downward slide plus the Perseid radiant does not rise high into the sky as seen in the southern hemisphere. Therefore, rates for the Perseids are greatly reduced when compared to those seen from the northern hemisphere.

During this period, the moon waxes from half-illuminated to nearly full during this period. This weekend the moon will set during the early morning hours allowing a few hours of observations under dark conditions between moon set and dawn. This window of opportunity shrinks with each passing night until mid-week when it lies above the horizon all night long. The estimated total hourly rates for evening observers this weekend should be near 4 as seen from mid-northern latitudes (45N) and 3 as seen from tropical southern locations (25S). For morning observers, the estimated total hourly rates should be near 21 as seen from mid-northern latitudes (45N) and 18 as seen from tropical southern locations (25S). The actual rates seen will also depend on factors such as personal light and motion perception, local weather conditions, alertness, and experience in watching meteor activity. Evening rates during this period are reduced due to moonlight. Note that the hourly rates listed below are estimates as viewed from dark sky sites away from urban light sources. Observers viewing from urban areas will see less activity as only the brighter meteors will be visible from such locations.

The radiant (the area of the sky where meteors appear to shoot from) positions and rates listed below are exact for Saturday night/Sunday morning August 2/3. These positions do not change greatly day to day so the listed positions may be used during this entire period. Most star atlases (available online and at bookstores and planetariums) will provide maps with grid lines of the celestial coordinates so that you may find out exactly where these positions are located in the sky. I have also included charts of the sky that display the radiant positions for evening, midnight, and morning. The center of each chart is the sky directly overhead at the appropriate hour. These charts are oriented for facing south but can be used for any direction by rotating the charts to the desired direction. A planisphere or computer planetarium program is also useful in showing the sky at any time of night on any date of the year. Activity from each radiant is best seen when it is positioned highest in the sky (culmination), either due north or south along the meridian, depending on your latitude. Radiants that rise after midnight will not reach their highest point in the sky until daylight. For these radiants, it is best to view them during the last few hours before dawn. It must be remembered that meteor activity is rarely seen at its radiant position. Rather they shoot outwards from the radiant, so it is best to center your field of view so that the radiant lies toward the edge and not the center. Viewing there will allow you to easily trace the path of each meteor back to the radiant (if it is a shower member) or in another direction if it is sporadic. Meteor activity is not seen from radiants that are located far below the horizon. The positions below are listed in a west to east manner in order of right ascension (celestial longitude). The positions listed first are located further west therefore are accessible earlier in the night while those listed further down the list rise later in the night.

These sources of meteoric activity are expected to be active this week

.

The kappa Cygnids (KCG) are active from July 23-August 27, with maximum occurring on August 14^th. The radiant is currently located at 18:38 (280) +43. This area of the sky is located in northern Lyra, 4 degrees north of the zero-magnitude star known as Vega (alpha Lyrae). To best see these meteors face northward near 2300 Local Summer Time (LST) when it lies on the meridian and is located highest in the sky. With a high northern declination, these meteors are difficult to view from the southern hemisphere. Expected hourly rates this week are less than 1 no matter your location. With an entry velocity of 21 km/sec., the average meteor from this source would be of medium-slow velocity.

The alpha Capricornids (CAP) are active from July 7 through August 13, peaking on July 30th. The radiant is currently located at 20:32 (308) -08. This position lies southeastern Aquila, 5 degrees northeast of the naked eye double star known as Algedi (alpha² Capricornii). Current rates are expected to be near 1 per hour no matter your location. These meteors are best seen near 01:00 LST, when the radiant lies highest in the southern sky. With an entry velocity of 21 km/sec., the average meteor from this source would be of medium-slow velocity.

The large Anthelion (ANT) radiant is currently centered at 21:32 (323) -15. This position lies in central Capricornus, 2 degrees northeast of the 4^th magnitude star known as iota Capricornii. This radiant is best placed near 02:00 LST when it lies on the meridian and highest in the southern sky. Rates at this time should be near 1 per hour as seen from the northern hemisphere and 2 per hour as seen from south of the equator. With an entry velocity of 30 km/sec., the average Anthelion meteor would be of medium-slow velocity.

The August beta Piscids (BPI) were first mentioned by Luigi G. Jacchia in his book The Moon, Meteorites and Comets. The BPI’s’s are active from July 28-September 17, with the peak occurring on the August 22nd. The radiant currently is located near 22:36 (339) -02. This area of the sky is located in northeastern Aquarius, 2 degrees south of the 4th magnitude star known as eta Aquarii. To best see these meteors look in the northern sky near 0300 LST, when it lies on the meridian and is located highest in the southern sky. Hourly rates at this time should be less than 1 no matter your location. With an entry velocity of 40 km/sec., the average meteor from this source would be of medium velocity. These meteors are also known as the Northern delta Aquariids (NDA).

The Southern delta Aquariids (SDA) are active from July 19 through August 13 with maximum activity occurring on July 30. The radiant is currently located at 22:51 (343) -16. This area of the sky is located in southern Aquarius, 1 degree west of the 3rd magnitude star known as Skat (delta Aquarii). This radiant is best placed near 0300 LST, when it lies on the meridian and is highest in the southern sky. Hourly rates at this time should be near 2 as seen from the northern hemisphere and near 3 as seen from south of the equator.  At maximum these rates increase to 10 and 15 per hour. With an entry velocity of 40 km/sec., the average meteor from this source would be of medium velocity.

The Perseids (PER) are active from July 17 through August 29, with maximum activity occurring on August 13. The radiant is currently located at 02:22 (036) +56. This position lies in northwestern Perseus, 3 degrees west of the 4th magnitude star known as Miram (eta Persei). This area of the sky is best placed for viewing during the last dark hour before dawn when it lies highest in the northeastern sky. Maximum activity is not until August 13th so current rates are expected to be near 5 as seen from the northern hemisphere and 2 as seen from south of the equator. With an entry velocity of 59 km/sec., the average meteor from this source would be of swift velocity. Viewers in the southern hemisphere have a limited view of this shower as the radiant only rises just before dawn.

The eta Eridanids (ERI) are active from a radiant near 02:34 (038) -14. This position lies in southeastern Cetus, 3 degrees west of the 4th magnitude star known as pi Ceti. This source is active until September 10^th, with maximum activity occurring on August 4^th. Current rates are expected to be near 1 per hour no matter your location. These meteors are best seen during the last dark hour prior to dawn when the radiant lies highest above the southeastern horizon. With an entry velocity of 64 km/sec., the average meteor from this source would be of swift speed.

The July chi Arietids (JXA) were discovered by two investigating teams in Europe using video data from European video Meteor Network Database (EDMOND), SonotaCo, 2013; and CMN, 2013. Activity from this stream is seen from June 26 through Aug 06 with maximum activity occurring on July 17th. The radiant currently lies at 03:16 (049) +15, which places it in southeastern Aries, 4 degrees southeast of the 4^th magnitude star known as Botein (delta Arietis). This area of the sky is best seen during the last hour before dawn when the radiant lies highest in the eastern sky. Current rates are expected to be less than 1 no matter your location. With an entry velocity of 69 km/sec., the average meteor from this source would be of swift velocity.

Sporadic meteors are those meteors that cannot be associated with any known meteor shower. All meteor showers are evolving and disperse over time to the point where they are no longer recognizable. Away from the peaks of the major annual showers, these sporadic meteors make up the bulk of the activity seen each night. As seen from the mid-northern hemisphere (45N) one would expect to see during this period approximately 12 sporadic meteors per hour during the last hour before dawn as seen from rural observing sites. Evening rates would be near 3 per hour. As seen from the tropical southern latitudes (25S), morning rates would be near 9 per hour as seen from rural observing sites and 2 per hour during the evening hours. Locations between these two extremes would see activity between these listed figures. Evening rates are reduced due to moonlight.

The list below offers information in tabular form of the active showers that I feel are within reach of the visual observer to discern. Hourly rates are often less than one, so these sources are rarely listed as visual targets in most meteor shower lists. If you are like me and wish to associate as many meteors as possible with known sources, then you will appreciate these listings. Before claiming to have seen meteors from these class IV showers, you should attempt to determine if these meteors actually belong to them and are not chance alignments of sporadic meteors. You can note parameters such as duration, length, radiant distance and the elevation of each meteor to help compute the probability of shower association.  It should be remembered that slow meteors can be seen from fast showers, but fast meteors cannot be produced from slow showers. Slower showers are those with velocities less than 35/km per second. Slow meteors can appear from fast showers when they appear close to the radiant or low in the sky. The table located on page 22 of the IMO’s 2025 Meteor Shower Calendar is a big help in aiding in the identification of meteors. If you record the length and duration of each meteor, you can use this chart to check the probability of the meteor belonging to a shower of known velocity. If the angular velocity is similar to the figure in the table, then your meteor probably belongs to that shower. Recognizing meteors from obscure showers is certainly not for the beginning meteor observer as it takes many hours to get a feel of what you are seeing. It is our hope that you will advance beyond watching meteors as a fireworks display and will want to help us expand our knowledge of the heavenly bodies we encounter in the skies above by classifying each meteor you see. Rates and positions in the table are exact for Saturday night/Sunday morning.

You can keep track of the activity of these meteor showers as well as those beyond the limits of visual observing by visiting the NASA Meteor Shower Portal. You can move the sky globe to see different areas of the sky. Colored dots indicate shower meteors while white dots indicate sporadic (random) activity. The large orange disk indicates the position of the sun so little activity will be seen in that area of the sky.

Class Explanation: A scale to group meteor showers by their intensity:

• Class I: the strongest annual showers with Zenith Hourly Rates normally ten or better.
• Class II: reliable minor showers with ZHR’s normally two to ten.
• Class III: showers that do not provide annual activity. These showers are rarely active yet have the potential to produce a major display on occasion.
• Class IV: weak minor showers with ZHR’s rarely exceeding two. The study of these showers is best left to experienced observers who use plotting and angular velocity estimates to determine shower association. These weak showers are also good targets for video and photographic work. Observers with less experience are urged to limit their shower associations to showers with a rating of I to III.
